Here are some pics I hope you can help a new grower,it’s afgan plant 6 months old I use fox farm nutrients and followed the schedule this is what I got
Looks like calcium and some magnesium deficincy
Do any leaf tips curl or twist upward?
I’m with @fano_man, calcium of magnesium deficiency! Welcome back!!
I would also check soil PH if it’s off it can cause poor uptake of nutrients
