Curling and cupping

Ok so I’ve noticed some of my smaller leaves are curling down in flower. I’m running in soil, always PH around 6.3 to 6.4 and my temps are mid 70s with a 60 RH at the moment. I plan to drop the RH to 50 this week but want to try and dial in these leaves first. Plants are in week 4, running a normal bloom base with added potassium sulfate and potassium silicate. Plenty of bio life going on in my soils so yeah I’m a bit confused on this? I am running a flush at the moment with fish shit and other bennies to see if I have some nutrients built up in the soil. 5 gal fabric pots by the way, run off seems fine, so yeah this has me stumped.

The dark green foliage is among the first sign you’ll see for N toxicity.

Classic clawing-too much N in the mix.

Nitrogen has been kicked back, the base bloom is super low in N and that’s the only N it’s getting. Your right though they are clawing like it’s N. It’s only on some of the smaller leaves mid level. Not all plants either so I must be dealing with a strain that does not like any N in flower. PS it’s gelly biscuit

as far as PPM I’m only running 600 on week 4 flower. So I don’t think it’s specifically my mix that’s N hot but rather this specific strain, my other two strains look fine. I’ll post back end of week and see if the flush is helping.
