Looks like phosphorus deficiency. Too much water can cause this or it is just purely lacking it. Good luck 👍

In coco you can not have too much water in one sitting. Is your run off ph 5.8?

Nutrient Burn, Leaf Septoria, Nutrient Deficiency? Or something else?I have been having issues with the Purple Haze. I've tried adjusting the Temperatures, adding additional Cal-Mag, changing lumen intensity etc. I believe this may be nutrient burn? Added an old image of leaf before mainlining, the plant is 1 week old after mainlining was done.
