Cal-mag is the main issue here.
On top of that there looks to be an abundance of N,
and either light stress or overwatering.
Back off on the NPK for a few watering cycles using only GP Procal [Calimagic, etc].
Watch for bounce back and colour fade.
If they do not straighten their tips its because they are shying away from the light; raise or dim your light.
Rough time to be having to play around as you are into the integral phases of flower site production, dial in the process so this can be dealt with in less crucial phases of future grows.
got a few issues but i think the leading cause is your smart pots sitting in its well? if so my moneys on a really high ec and and too high or too low PH if im right and its out of whack, correcting these will make your plant love life again, also try to use less N its stunting your growth, making thin leaves, curling down and if you dont flush at the end the buds will taste nasty.
