Yeah I agree with roberts, looks like a few deficiencies happening..
I see some nitrogen and magnesium deficiencies from the yellowing as a whole and interveinal yellowing/browning
Like roberts said, a pH issue could be locking out nutrients

Looks like a mix of things going on. I would guess a ph lock out. Check substrate run off ph.

Yellow leaf tips and edgesYellow leaf tips and margins… what do you think? Nute burn? Light stress? Cold stress?
Will this eventually resolve if I leave it alone and let it work itself out? (Which is what I’m inclined to do)
Should I flush my plants or try some other intervention?Week 8

Leaves curling into budAs sugar leaves send their nutes to the buds and start to curl/die, do I need to trim them off before the curled part reaches the buds? The fan leaves were an easy choice to trim...sugar leaves I’d have to trim the leaf rather than stem. Is that ok or necessary?Week 11
