severe yellowing in week 8...

[WidowMaker]

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"??

I had the same problem with bubblegum.
the answer to my problem was.
i cut the nutriants by half for a week and raised the light another couple of inches. after a week it started to cure.
Another thing it could be is dead salt build up,flush the system with fresh water for a day.Then start the process as normal.

if you can check the ph too. I would have thought it to be normal but if its only 8 weeks then it hasent (most likely) started to flower yet. And if you dont know during the flowering stage its not un-normal for the big leafs to turn yellow then die. It just the plant using all the stored energy for use during the flowering stage. Let them die and dont pluck off. Sorry if you already know this, just thought you might want a heads up bout that. And it seemed related, but then again who knows cause im stoned, lol.

i pearsonally would not advise taking cuttings from a regenirated plant as i have done it in the past and it turned a good strong smoke into shit e
