1 DWC,2plants,1 sick ??

[dancer]

Hello

I have an odd situation that I would like to get some advice on.
I have 2 plants in a DWC,over 4 weeks or so in flower and the other has had yellowing, falling off leaves for some time now, looking like N def. to me. I tried to fix it by adding extra N to the res for few times but it did not stop yellowing. Now the yellowing had worked it's way all over to the top of the plant and most leaves have fallen off, it is a lot skinnier than the other and not impressive looking at all.
What could I do to fix this?
They a under a screen so I cant separate them...
Thank you in advance.

Why not try a water flush for a couple days. maybe an imbalance in the rez. You have 2 plants feeding differently on the same nutes. She may be locked out due to too much of 1 thing. You didn't mention pH.

Ok, Ph has been under control 5.7-6.0.
I post some pics in half an hours time.

[dancer]

They are now in plain Phed water as suggested. Enlighten me, why did I do that?
What am I expecting now to happen?

Pics of the difference
Well the pics doesnt really do a favour to the difference but first is a piece of the suffering one and other more healthy, about 3-4 times smaller already....

Pretty much all leaves have fallen off by now..
I do not know what to do next.

Did this start about day 20-25?
do you see any bugs flying in the room?
Most likely it's Root Aphids, not nutes.
to late to do anything this far along in bud to completely stop them.

read the root aphid thread
