I have 3 plants in a flood and drain system...I use GH nutes according to their instructions...I had to pull a late male at 21 days and noticed the plant next to it yellowing...I suspected root shock, so I didnt worry...then it didnt recover in 2 weeks so I suspected magnesium was too low and added epson salts...no recovery and now the other 2 plants are yellowing...it seems that only the older top leaves are affected, so I suspect nitrogen is real issue, and am not gonna decrease the floragrow below 3ml/gal as I am regenerating these mommas to clone and reharvest at least once more...my question: "Is this normal with WW with GH nutes?? and if so, will keeping the flora grow at a higher rate solve this in future crops"??
