First "Real" grow and my plants were looking fine until I notice some issues. The first picture the tips of each serrated tip are slightly curling up. In the second picture there are a few yellowish/brownish spots on the leaves. Some leafs have 1 or 2, some leaves don't have any. Is this a sign of a nutrient deficiency or possibly heat stress? I'd appreciate any help I could get.
Looks over watered. Is there drain holes in that bag? And are you watering the leaves? If yes stop that
