J0hnny80y Unsure of actual age. Purchased as a Rainbow Chip clone. Photoperiod/Autoflower unknown. Added a 1/2in layer of organic worm castings about a week ago.
Looks like abit of nutrient burn. Perhaps a little too hot on the castings. If this is an auto they can be sensitive to nitrogen. Pot up or just water for a while to halt burn. If burning increases significant consider a flush with ph'd water. Hope this helps
