thats what i was thinking. the roots stopped growing for the last few day. they look a little better, but no new growth. it was in a differant res. the male that was with it had it to. this res is tight.

stick your nose in the tank does it smell bad? all the same i would invest in a bottle of pythoff or someother root sterilising agent. the best thing you can do is treat the water with a Ultraviolet lamp pumping the air around the lamp in to the water using you air pump do a google for "vecton uv sterilisers"

if its the dreaded "P" (pythium) you can bet all your weed on it, it will spread to all the plants in your system, that is if you harvest any weed at all. pythium is the worst thin a grower can get it can totaly destroy a whole crop in days and you thought spider mites were bad? once you get it you have to steralize everything pumps tubes pots evrything or it will come back.yea it smells, will it spread to the other one? i will check out the uv deal, thanks for the info
what is your water temp?
p.s
iv know growers throw out their systems once they have had it

you need to keep the water under 70f if its over 70 then its just asking for root rot. get some space blanket to rap round the tanks its only thin stuff but it reflects 95% of the infar red heat away from the the tanks. its also god anti heat detector line your walls with it and no heat will be seen from out side with a thermal imager, you know the stuff runners rap up in after a race? it cheep and comes in 2 x 1.4m and costs a lot less than mylar they sel in grow shops gold on one side silver on the other.

yes, i highly recommend Hygrozyme for pythium, but before all this theres a few steps you should take , like giving your whole system a hot bath, i prefer hot water with h202 or alcohol, run the system with that water, clear it out, then add hygrozyme or another enzymatic product, this will eat dead roots, make the waer look nasty for the first few days and stimulate amazing root growth, gotta have it with hydro, its a condom for your roots

usually high temps bring on pythium/root rot, your golden at 65-68F. how often do you change the rez? see root rot is brown , i dont get it being green, is there anyway your nutrient solution could have stained them? algea is lime green to dark green, pythium is brown and slimey, either way u need a root protection product

oh, i hate what u did with those cups, need more holes, u should get good uptake the roots grew nice and large, next time either make a shit load more holes or use net pots, its hard to tell the color of roots with the flash it makes them look brown, the plants up top look great, a lil stretched nonetheless healthy looking, dont fuck around and get the zyme, my opinion, i would gently try to cut those cups in half and i know u wont be able to get the roots out of there just let it hang or snip pieces of the cup off, to get a nice even canopy you can bend the tops of the large one down then tie to the main stem, or it will overshadow the lil one and will not recieve good lighting, get the lights closer, like 6-12 inch above canopy until it makes your hand uncomfortable, for now u can use hydrogen peroxide h202, if its 3% a tbsp a gallon or litre should be ok, if you get 35% 3ml/gal or half a teaspoon/gal every 4 days, that should kill anything like bacteria or the algea living down there

yea i have 5" net pots. i was going to transfer them, but was scared of hurting the roots. the light is about 10" from the tall 1. never more than 12". i do not know why the tall 1 shot up. 6 of 7 where growing about 3/4" per day. the tall one was doing 2" for about 10 days. the roots are light green. the bigger 1 has a little green tint at the bottom of the cup. i have dutch master zone should be here tomorrow. it should take care of any algae type shit. dutch master says no h2o2, with their nutes.

have you looked at the roots in proper day light? if you are looking at them while they are under HPS or MH colors will look differant roots are white may be you are geting a refection from the green from the plants on the root = they look green. take them to the window and have a look and take a pic.
p.s
take a pic of your nute in a clear glass is your nute green in color? may be its staining the roots if it is. your plants growth looks to be doing o.k almost 1" a day is good going.
