Hey there , itโs hard to tell without a complete diary but that looks like a combination of light and heat stress and calcium - magnesium deficiency due to light stress. You can tell from the taco-ing of the leafs and the yellowing affecting the newest leafs first , discoloration on the serrated edges of the leafs , and the rust colored spots. Try to increase or add calmag and reduce your light cycle as much as possible to fix the root cause. Hope this helps ! ๐

Brown spots on leavesWhat seems to be the problem with my plant? The old leaves get brown spots whereas the newer ones have yellow edges. Is it a pH issue?
Is there a fix to this?
I grow in soil and the plant is 4-5 weeks old.
Thanks for help!
