I flushed them twice now and buds are looking good and I’m usinv Fox Farm and I think im missing something and I’m not using a hole lot
I just went thru something similar and I think it’s because when you flip to flower youbstill need to feed nutes that have high nitrogen to accommodate the stretch that happens the first 3 weeks or so. You’re plants right now are using up the nitro from lower leaves to power the stretch. I ended up including some veg nutes when it happened and seemed to help. This is my take on it. May be wrong.
