Do you use any calmag? Stems look purple suggesting a deficiency or lockout. Could be because your PH is out. Tips are burnt like you are using too many nutes
What are you growing in? Can we see a pic of the plant. You could try a foliar spray of Epsom salts to see if there's a mag deficiency, or mix a little into your next feed.
Hello, and thanks for all the replies, I am using a 50/50 mix of peat sphagnum and ocean forest soil with plenty perlite for drainage, plants are 3ft tall plus, in 3 gallon pots, maybe time to repot.??? These plants are clones from 6 generations and started off with larger leaves and have diminished a bit each time,potency and yield are still good though... I will post full plant pics tomorrow, thank you so far, and God bless
aside of whatever is happening nutrient wise with your plant... you have a really bad case of thrips my dude. look on the underside of those leaves for little crawling larvae.
