Hello all ...i had this same problem in my last grow...i have been doing everything by the book...as soon as i saw roots coming out the bottom on the 3x3 rock wool cube i put them in the pots added the rocks and set them up to flood and drain 3 times a day ...up until this point i was watering by hand2 times a day.... i put them in my ebb and flow ...this was Sunday evening ...by Monday night i could already see the new growth begin to turn yellow and some of the existing growth on the plants have also begun to yellow...its only Tuesday and they were perfect Sunday night ...i have scrubbed everything with bleach and disposed of everything that was replaceable...i thought i have kept them in the rockwool cubes too long last time (2 months) and they might have gotten root bound.... but they are just 3-4 inches tall and only 3 weeks old this time im so confused...what should i do ...???

(merged) Can any one answer this...it seems pretty simple but cant seem to get anything in plant problems to match ...i keep having a problem when i switch from one growth stage to the next ...i had ak47 and burmese kush plants in 4x4x4 rock wool cubes which i watered daily by hand with a basic flora nova grow and hygrozyme nutriernt mix the plants flourished ..i did this for almost 7 weeks and was able to sex out the true males...i then took my remaining females and put those into a 4'x4' ebb and flow Rating: 5
