30 days at12/12, i have yellow, curling-HELP please

[ClosetCase]

Im growing in rockwool in my closet.My nutrient still reads 1.4 even tho i add low ph w/o nutes water to bring it down.I think i have root crowding,tho its too late to modify my nutrient resevoir.I have lots of small flowers about nickle size,should i give them less light to increase flowering before the plants die so that i'll get some yield?No matter what i feed them,the leaf problems continue.Also ,adding ph down raises the ec reading to a scary place.Help me please.Thanks

How often are you changing out your nutrients? Have you ever flushed? We need to know all there is about your set up. Like room temps and res temps and all sorts of things. Without knowing everything going on, we can't help.
