I have 2 pictures of leaves with brown spots almost looks like it received too much light. Is this a result of too much light or perhaps Calcium deficiency?
You added so how could any one say cal/ mg deficiency. May be it is. Check it out Max gro i would use for soil. Mic/gro/bloom is better for coco. I think lol. Know with the MaxGro go with half of what u gave last time. Then you can try your dose on next watering so you dont burn her up
Your brown spots are cal/mg deficiency. I use LEDs where it is always an issue. 1 ml/l of a good cal/mg additive will solve it. Those leaves will get leathery & disgusting. I am also growing Pink Kush . . . 😎
