well I havent fed them in a while. Probebly gonna water tomorrow with Big Bud.
they should be finishing up within a couple weeks.
b4 your leaves looked like that, did they turn yellow?
from my limited experiences, when you feed with low N bloom formulas the leaves will slowly turn yellow and fall off like your pic. this is normal!!
i usually start picking them off my plants as they become very yellow and easily pull off the plant.
to me it looks like you have some kind of nute burn or nute lockup.
just my two cents. maybe someone else with more experience can tell you.
