bottom leaves yellowing+falling off

i have a plant that is flowering for about a week or two now.

the bottom most fan set started to get yellowish, so i mixed up a bit of nute+ph water to try and stop it, but it made it worse

they get super pale yellow, and totally just fall off

they come off like just by touch

this happens to another plant i have when i water it

it is a recent problem

anyone have any exp?

i'd love to see some pics but from what your describing it sounds like the plants slowly dying.. you might be over-killing it with nutrients, bright yellow leaves means an iron deficiency..
also what nutrients are you using? what strength? whats the resivour/soil PH? (if soil, what's the run-off PH? if hydro, what's the EC or PPM at?
hope it works out for ya bro..
