My guess would be youve got some salt build up going causing some toxicities and locking out some others causing deficiencies. It appears that you have some N Tox going on judging by the dark green and glossy leaves, that can lock out calcium which it appears to have a deficiency of also. Id flush real well, maybe with a salt clearing product like floraKleen, then give just pH'd water or very light feeds the first couple waterings afterwards. Good Luck!

They are in a peat moss compost, i have been adding in 0.8/1ml/l into feedings of vitalink calmag. Just flushed with 6.0 ph water to clear anything in soil and added in a light feeding after with some calmag and bloom nutes to see if this will help her out

Indoor LEDs grows usually need some light calmag in the feedings. What are you growing in? Soil requires less then say coco. 🌱
