Are they supposed to be nice and white and if yes what do i do ? stop ferting?

Go buy some pirahna. It is an advanced nutrient it's really costly like $40.00 but better then having nothing to show after all the hard work!

hwo do roots turn brown in hydro>?

what are you using? Is the question...and Piranha is useless unless you have the regimen to support it.

You don't have to already use the Flora series or other Advanced base nuts. for one to have an effect on a plant or system (if that's what you were saying). You can use GH, Organic or and combination of base nutrients and still benefit from the use of one AdvNut product. I'm sorry I usually agree with you but not on this because I know people who have used piranha and voodoo juice just as a reservoir treatment without using other AdvNut products. It promotes healthy roots and the organisms will breakdown the rotten roots. I agree there are other options and the more information listed the better the response but it wouldn't hurt. Stoner Thought here: Maybe you were talking about the toxicity level in his reservoir; maybe that cannot support life even at the microbial level if the PPM is too high. ANYWAYS I'M HUNGRY!

I think we really need a pic on this one. I will take pic's of mine if need be. My first grow was nothing but dynagrow and roots were white. Next 2 grows were GH 3 part and Lucas formula this time, B-52, Cal-mag plus. My roots are the color of my res. Kind of browny red. They also look like they are dragging down some of the rockwool cube they strated in. We need the whole story. Mine are doing very well.

sorry i just read these il post a pic later if possible.

Im using ionic grow hard water cause it doesnt need ph'ing.., i need a cf meter i dont know the ppms but ve been half dosing, i havnt done hydro for ages ive just started again.

i put 2 cuttins per block and im getting 1 small plant per block, and 1 large per block. Not sure how roots looking as i write this.. plants are ok just a bit flimsy cause i need more light.. and wind.

As for other nutes ive got bio bizz soil grow n bloom.. (plus biobizz soil if needed) canna pk.. pure N, liquid oxygen (oxy plus), silicone plus (awkward to use)

i have acid test kits n phospheric acids..

ph is about 6 or just over.. water is COLD i need a radiator still..

I need an air bubbbler too keep the water moving too.... i hate cleaning these tanks how do you remove all the dried ferts?

Thanks for your time people

havin probs taking photos of the roots at the moment its too dark without flash and too bright with 1 and im needing sleep. Heres wat i have, manky looking top of block.. (need some guardian angel?) maybe u can vaguely make out root color.. ive cleaned the tank and fed it small doses of PK and N i dont know if i should have but il find out soon.. as you can see they look ok a day or 2 later...

Unless your water temperature drops below 60F, you don't need a heater. Roots are healthier in cool water and can hold more oxygen. Warmer temperatures actually promote root problems.
Sometimes additives stain the roots brown even when the roots are healthy. Unless they are brown, decaying and slimey I wouldn't worry. When I have had root rot before, it smelled bad.

okay thanks, well they arent slimey and smelly so hopefully they will be ok

cyberbud:

hard 2 say. This was my first run, nutes in res are brown like medium-dark tea. Plant roots got brown a couple months ago (I also couldn't tell for sure if from nutes or rot). The plants are still green and healthy, but resin production for the strains isn't nearly what it should be so I know the roots aren't as good as they should be........ but whatever it is hasn't killed them and it's been a lonnnng time.
I've read that once infected, the root rot just progresses, eventually kills the plant. So probably my brown wasn't (all?) root rot. I think the roots can be pretty unhealthy and still not be infected with Pythium (especially if you're running peroxide or microorganisms to keep it away).
If your nutes are brown it's pretty much useless to judge by the color. The best way I've found to tell the health of the roots is the smell. At the beginning, when my roots were the healthiest (and also white, before the staining), they had a sharp, slightly acrid, fresh-root smell. It's very similar to if you pull a carrot out of the ground and smell it (if it's grown in uncompacted soil), a bit bitter even.
Once you know that smell it's unmistakeable, and that's the best way to tell. When they start to get funky, they get a smell that's more like the carrot after it's cooked -- no sharp fresh smell anymore. As time went on, only a certain percentage of mine kept the good smell, but the color on all was pretty similar.
Be nice to find some nutes that are clear...........................I've never tried GH.

Hey Cyber,

Brown slimy roots are a serious serious problem..

love

You need to clean out all the dead matter (all of it). Use a fish net and get BUSY!!! Dead matter uses up valuable oxygen... this is s serious matter , cause not only are your roots dying but the dead matter is making problems worse!!!

love

Cyber rotting roots are very hard to recover from..!!!

You will need to start a hydrogen peroxide regiment ASAP.. You need to add air stones!!!!!!!!! YOu need to get OXYGEN in.. DEAD matter OUT!!!

love....
