Thread: Plants leaves(Turning white)

Iv'e been trying to figure this out for a while, but still no luck.
I don't think it's an iron defiecency problem.
It started 2 weeks ago, it started on the bottom leaves, one leaf at a time it slowly became white, then the other and then slowly died(leaves).
The plant is healthy, but now it is starting on it's 2nd to bottom set of leaves. Iv'e looked at the leaves with a magnifying glass, and i don't see bugs. It isn't white spots, it just slowly becomes white'r, and white'r.
I will try to post some pics up tomorrow(getting new light ), it bums me out though that the plant is getting sick when it looks healthy.
Pics soon tried with camera phone, but didn't want to give you guys a headache from squinting(Bad quality). I will try and find my camera tomorrow.

Are the tips also white? If I would have to guess without pictures, I would say it's a Mg or Zn deficiency. Maybe even a combination of both. Get some pictures and fill the new sticky troubleshooting form out and someone will be able to answer.

Oh and the reason I think it could be either of those is because Mg deficiencies tend to yellow and white starting at the bottom and eventually dying and working its' way up. Zinc deficiencies usually have white areas forming on the tips and between veins. Soil is probably really alkaline. Need to check that Ph. If so, you can bury some galvanized nails in the soil. They have Zn and help aid to give that micronutrient to the soil and plants.


P.S. Your welcome! (for getting back to you so quickly! )

Thanks man, i was going to take pictures but when i started to load it on my phone i was like dear god no, lol. It hurt my eyes just looking at it, The whiteness seems to start from the middle of the leaf then work it's way, and then slowly to the other leafs on the branch.
And great response time

You know, it could also possibly be a Iron deficiency. my guess is one of the 3....once the pictures come it will be easier to tell then.

Do yourself a favor and get on that PH. Mg and Zn become unavailable in different PH ranges. Mg is good from 8 down to 6 but below that availability rapidly drops. Zn is good from 5 up to about 7.2 then it's availability falls off. Unless it's some kind of rootbound lockout, it's likely 1 or the other I'm guessing.

Really shouldn't be Mg since you have been feeding it. Could be Zn, Zn works hand in hand with Mg within the plant producing enzymes and stuff. Could manifest itself as both maybe if only one was missing?

How long has the same plant been in the same pot? Have you ever flushed?

I just moved it into the pot it is currently in, about 5-6 days ago since it's now technically thursday.
Im going to give the galvanized nails a try i think i have some, and yes iv'e flushed it before but not in this pot.
I will try to get an electronic ph tester this weekend or sooner.

I found my digi camera, and i will take pics as soon as lights out.

My guessis that your pH is out of wack!

Also, if it isn't your pH, too much phosphorus can block the absorption of iron

I would advise that you give it a good flush and then see if it rebounds.

The reason i think it has something to do with Fe is because the leaves are turning white. Fe is critical for chlorophyll production, without it, chlorophyll is not produced.

Yeah, well i use filtered water because who knows the tap could be worse :P.
I have a water treatment solution nutes, It seems that it might have slowed or stopped, but i will take pics when lights out tonight.

Thanks

Not necessarily true....Tap water (if PH is correct) is actually pretty good for your plants. They have essential micronutrients in it that aids for cannabis. You should let your water sit for 24-48 hours (open top) to rid of the chlorine in it, but that's about it. If your Ph is correct with the tap water, then you should be fine with everything else.

That's if the ph is correct, which i do not know. So up until this point iv'e had no problem with the water i have been using.
Ill get pics up in about an hour.

Yeah, on my first grow I didn't have a problem with it until flower. My Ph was always between 6.8 and 7.2 then one day it was damn near 8.2 I was like WTF! Ha, sometime that small can cause major problems (i.e. lockout). Anyways, look forward to the pictures, so we can clear it all up!

Yeah, this is my first indoor grow
I realized something today, that i should never pursue the profession of a photographer
Now, wait you've all been waiting for.
The lowest set of leaves were the first, and i fear that the second set will be next.
I got some galvanized nails(or i think, and im trying that until i can get a ph tester)

*Updated trouble shoot form*
~~~
Your Equipment:
.1) 150watt hps, 2x60watt
.2) 5'(or so give or take)

.5) Circulation
.6) 150watt, and 2x60watt, lighting schedule 18/6 atm

Your medium:
.7) I don't know the brand potting soil, i had laying around. I added cal-mag 7 days ago(give or take)
.8) 5-6Gallon i forget.
.9) idk

Your nutrients and water:
10) Filtered(Don't have a ph tester yet)
11) None
12) None
13) Specific brand and N-P-K ratio for each bottle. List dosages (quantity per gallon) and current feeding schedule.
14) 2-3 days(depending on how moist they are etc)
15)Cal-mag

Your growroom:
19) Indoors
20) 7foot cab don't know the rest of the measures(written down somewhere...)
21) 78-85f(Lights on), lights off 70+(Don't really monitor that often)
22) Nope, cedar so i don't think i have any.

Your strain:
23) Blue venom(Indica dominate)
24) Seeds
25) No.

you've got it under how many of what type of fluorescent(s)? how far is it from the top of the plant? did you get the HPS? there looks to be a lot of stretch and sparse growth. looks like it could be a lack of light. not that pH isn't a factor as well.

get a meter or freshwater aquarium test kit.

how old is the plant? what type of soil and what nutes are you using? when was the last feeding?

you might want to fill out the troubleshooting form. it's in my sig. just copy and paste it here.

I don't think it's because lack of light, the other two bulbs are angled to get the sides of them. Yes, i got the hps, put it under it yesterday.
I am going to get, an electrical ph tester this weekend or tomorrow.
At the moment, the only nutes i have recently used is cal-mag.
I am using some potting soil i had, the last time i watered was 2 days ago wednesday, i did fill out the trouble shoot form.

Thanks

I think it is, the white fly i have read about them, and haven't seen them up until this point. But i do think it is this, it was a small thing flying directly under my light.
*Yeah there are quite a few, google time and if anyone knows anyways feel free to share*

Ordering, white fly traps and ph tester tomorrow.

what fluorescent(s) did you have them the plant(s) under until the HPS? 2, 60 watt fluros? and you have them 5 FEET away? if this is the case then i don't know how you can argue that it's not a lighting issue, at least in partial.

and the HPS you got was a 150 watt?

and you must have been filling out the troubleshooting form as i typed my response.

I don't have them under the fluorescents anymore, and no not 5 ft away.
More like 5inches
Yes, i have them under a 150watt hps.

well it said 5' (feet), not 5" (inches) in the troubleshooting form.

did you get the pH meter ordered?


-shake

Yeah, i ordered the test strips though, I didn't think that an electronic one would be as expensive, as they are.
Oh, and sorry my mistake about the inches and feet.

no sweat man, just trying to help out.

you can find a digital pH pen on ebay for ~$25.

Thanks, ill try and get one next week(depending on how well the strips are).

Strips work, but they get costly then a pen after awhile and you end up using a few everytime you water to check the Ph before you water, after the adjustments, then the runoff after that. Just a hassle.
