I am looking for some help from someone here who is the PRO at growing hydroponically and who might be able to give a helping hand to a person in dire need! I am on my second grow ever, first turned out all men

Second group of 4 is now only 13 days old. I do have some problems, and growth seems slow. If a PRO reads this and is willing to help me out, I would greatly appreciate it.

Right now I have 4.

first: looks great, just growing slow as all can be. some leaves have twisted, just a little.
second: looks terrible, I think is is naturally deformed. "retarded" if you will.
third: Probably has grown the best and has the best roots, however two leaves on lower growth have some yellow spots on them that look like burns or something. New growth looks fine, but again... SLOW.
fourth: Some DARK green leaves on it, and now showing some signs of orangish spots... not good. a little twisting of the leaves here too.

My setup is as follows:
1000 Watt MH system. about 3.5 feet away from plants.
Room: is a closet about 2.5ft deep x 7ft long x 8ft Tall
I am using 5 Gallon buckets filled with RO/UV sterilized H20
Dyna Grow "GROW" formula 7-9-5 for nutes. added about 1 TSP of Fulvic Acid
My PH is 5.8 in all buckets and PPMs are all around 550-600
My temp is around 85 during the day and cools off to around 72 at night
lights on 24/24 currently.
Not sure of water temp. One day it seems warm, next day it seems cold.
4" Round air stones pump clean air into buckets and onto roots.
2 small fans for ventilation and circulation running.

I have recently pulled out about half the water in each resevoir and added fresh RO/UV sterilized water without nutes... PPMs at ~600

If you are a PRO grower, meaning, you grow time after time after time, and know what the heck you are doing.. (hydroponically ... mind you) please help me out. I would really appreciate it.

Sounds like you need Zandor's 2 new books as I am waiting for them also. I hate for the man to have to spoon feed me. Are you using the UV like a pond or fish thing I've seen to kill stuff or is it just done when the water is RO'ed ? Are you using any Cal-Mag plus ? sounds kind of like the cal-mag. You have to add it back for RO water. Bubblers in buckets, are you keeping the water level just under the net pots ? I used dynagro my first time it did good but go for GH 3 parts when you can. Sounds like your doing things right. What kind of venting are you getting, outside air or what ?

What type media are you using? Sometimes improperly flushed media can cause all of these problems.

Forgive me for intruding as I don't qualify as a "Pro"....But I noticed your Dynagrow formula had a higher P percentage than the N percentage.....

Most grow nutes ...at least for soil...require the Nitrogen compounds [N] to be in higher concentration to Phospherous[P] and Potassium[K] ...

During flowering the P ratio must be higher than all other compounds....It's to do with the plants different nute requirements ...

Perhaps you knew that already but it just seemed a little odd that your nute formula had a strange composition....Maybe the lack of Nitrogen is hindering growth.....plants do take a while to grow though lol and growth rate is genetic and strain dependant...

depending on their size...day 13 might be a little soon for nutes! By the way, generally when leaves twist; It is a PH problem

Buy Jorge Cervantes-The Indoor Bible...I got mine used, but looks Brand new at Amazon.com for 10 bucks...

No, I buy the water in 5 gallon jugs, i just know that is how it is treated.
So I need Cal-Mag Plus? Water level right now is touching the net pots. I have read many things on this site that have said to get the GH 3 part nutes. I think I am just going to break down and get it this week.
Ventilation is outside air, sort of. I have a window open in the room that contains the closet. This window is only cracked as it is probably 20 degrees F outside where I am! But the room is a toasty 80 F due to the 1000Watt light.

Thanks for your help thus far, any further insight would be a great help.

Hydroton balls and rockwool cubes in a net pot.

how often should one flush this type of setup? and how?

You are not intruding. Thank you for your post. I did notice that about the Dyna Grow, and I am probably just going to get the GH 3 part system this week and do a full flush of the buckets and use the new nutes.

Yes, I am not even sure what strain this is exactly. I was told "Shiva" but it smells like a skunk to me! LOL!

I was wondering about this... That is why I asked for the PRO grower in this post. I would LOVE to know what PPM levels and PH levels people are using when EACH WEEK when they are getting this incredible grows. I am pretty much wishing for day by day instructions or something, because no matter how hard I try, I seem to be making mistakes here and there.

I am going to try and post some pics of them later for all to see. maybe that will shine some light on what they each look like and help determine what my probs are if any.

I saw that book on Amazon... does it deal with Hydroponics though????

I know dirt is a little different to deal with (PH diff and everything), and I have spent all this time/ money in hyrdo, so I would like to stay this way.

It deals with everything and Jorge updates this book each edition...so make sure to get a late edition...This book is everything any of the experienced growers here can tell/teach you. After you have it, you will understand alot more than can be explained on these forums...and when you need help to understand something, we will be able to clarify info for you...

DAy by Day...this is hard...let's say I tell you everything you need and you get it, but everybody on the forums want to stick in there 2cents in...you start doing different things and the whole mess gets confused...

1. Read the 4ums and develop a plan to grow
2. after you develop a plan and equipment you want to use, post it and we will critique it, and set you straight. You make the choices. lw

I have grown hydro from the start. If you find my threads, you can see some Monster growth...all from DWC...I also grow in pots using Schultz Orchid Mix/perlite/peat moss...with the same nutes as hydro (awsome plants...Only difference is I have to change ph average 5.8 for hydro-6.5 for soil

Some threads of mine are...latewood's little room...Misty Blue/BBJack grow report...clones in 10 days/homemade bubbler...sticky: Madman goes aero
cloning directly to hydroton bubbler...or something like that...Look in hydro and indoor forums 4-5 pages deep for my threads,,,I have quit posting lots of pix, because I was getting too well known...later.lw

Ok here is what sometimes happens. Water and nutes are allowed to dry on your media. Once the water has evaporated the nutes are left on your grow media each time you water there after some of these excess nutes become once again soluable and available to the plants roots. This excess causes slow growth, twisted leaves, and deformed plants. I know you said this is your 2nd grow are these the same hydroton balls you used for your first grow? If so how did you rinse them?

PH for max hydro yield is 5.8 - 6.5 or so. Dissolved solids in PPM for seedling stage is 450 - 600 PPM, for Vegg is 600 - 1000, and for flowering 900 - 1400. These figures will give you close to maximum growth with most varieties. I would also recommend the Jorge book it is excellent.

Herbus

6.5 is way to high a ph for hydro (even though it is stated MJ will grow at 6.5ph...It is not an optimum ph for production)...5.4-6.0 max...most experienced growers start as low as 5.4-5.5 and let it rise a little during the feeding period...otherwise, this is good advice.

The question about cleaning hydroton is valid. You use a mild bleach solution, soak it for an hour or so and rinse rinse rinse rinse, to make sure the
bleach is ALL GONE before you re-use it.

LW in my 6 years of experience I've noticed no difference in rate of growth or yeild between 5.5 and 6.5 PH. Nutrients remain in total solution throughout this range. I've tried both (6.5 and 5.5) from start to finish and they are the same in my experience. Bleach does nothing to release bound minerals, in fact it can increase toxicity even when well rinsed. LW I'm a chemist by trade and the advice you are giving may work for you but is in fact not correct. You seem a nice person I'm sure you mean well. Chances are this persons problems are caused from toxic salt build up in the media.

Well, I guess to answer both of you guys, the answer is NO I did not re-use the Hydroton from the first growth. Its new, and rinsed.

However, I am sure one day I will need to wash it, so if not bleach, then what?

Also, if I have build up NOW, what should I do to get rid of it? And how often do you need to rinse the media when growing? Like I said its only been about 13 days and I saw problems at around day 9 or 10. All new growth seems fine other than the fact it is slow as can be.

The only thing I DID re-use from the first growth was the net pots.
And two of the buckets. But the two that I re-used does not seem to be a reflection of a problem at all.

I really need to get that book tomorrow or something!

Well slow growth can be caused by many things but judging from the conditions you listed above the only thing i can think is toxic build up on your media. This is also unlikely as if this is new media toxic build up would not have had sufficent time to occur. The right thing to flush with is something to break the bond between the various calcerous / binder materials. I use Florakleen for just this reason. Bleach's active ingredient is chlorine. Chlorine is a disinfectant and so is useless for this application. The book is great but I think we covered the bases here. I would flush with 25% nute concentration and see if there is any improvement. Also a photo would be helpful.

Herbus

Disinfect with hydrogen peroxide. It's cheap and it works.

I have the Pics attached. These four pics are just the first two babies. I took a top view so you could see new growth, and then a bottom view so you can see the problems that I was talking about.

I will post another with the other two plants pics in just a sec...

Again, I took pics of top so you can see new growth and bottom so you can see my probs. It is baby 3 and 4 in this one...

And thats about it. I need these tomatoes to really take off. They are my medicine, and I wish I was joking.

P.S. Today is DAY 14 from the date I placed the seed in the paper towels.

Are there any roots showing yet. If so what color are they? Looks like you may have fungus coated roots. (invisible to the naked eye but roots will be off white or brown because of it) How often are you watering and how?

Herbus

Yes there are roots showing.
Its hyrdo... the bucket is filled with water to the bottom of the nets and there is a 4" round stone creating bubbles to the surface...

1roots1.JPG

1roots2.JPG

maybe that will help.
Looks white as can be to me. And compared to my roots on my first grow (pretty healthy...) they dont look off-white nor brownish.
At least in person they dont... picture makes them look a little off.

If that is the prob, how would the fungus start so soon in such a fresh new environment and how would I rid my system of it without hurting my friends.

So are the roots dangling in the water or are they above the water level? Also have you checked these plants for spider mites?

Herbus

Dangling in water.

And I check them everyday with a magnifying glass. Not to mention it is WINTER here, so I doubt there are any bugs ANYWHERE right now! lol

COLD!!

Well I just noticed in your first post you say onto roots so it seems like everything you are doing is right. Just check for bugs and maybe move your light down a bit as soon as they get a little bigger.

Herbus

Are the roots in any way submerged within the water as opposed to just being misted by bursting bubbles? If the roots are submerged then just raise them up so that they are no longer submerged and your growth rate will increase.

Herbus

Thanks for your help Herbus. No bugs, so I am clueless.

My 1000Watt light does not seem as bright as it used to be, so I am getting them to send me a new one.

In the meantime, can I use those florescent curly bulbs to supplement?
