overfertilised

Hello stoners,,
recently had to flush out my girls(night shade) for overfertilising actually did it the week b4 also, now i cant seem to get rid of the leaf yellowing, there ph is cool im using NFT hydro with canna flowers/ boast / wee bit of rizo and canzy and also added overdrive. there 5 weeks into a 7/8 weeks cycle, the buds dont seem to be doing a wild pile either. can anyone help

in my experience once a plant has been damaged the roots are bad and things do not go well. Most people say to flush.

try adding just liqid nitrogen from grow shop

never heard of that gear but thanks i'l try it
