First photo mechanical damage to stick from wind and brushing. Second - clawing leaves, nitrogen toxicity. Slow down with food ! Less is more in weed growing. Golden rule !

Leaves curl, become crispy and have weird colors I need help. I've not had this problem before. The leaves get crispy and have weird colors. However, the buds continue to develop as usual. What could it be? Not all plants are affected. But it spreads slowly.

Leaf damage/discolouration The yellowing is from an earlier issue but now I'm noticing brown spots and the leaves curling up, some getting crispy-ish. I recently lowered the lights a few inches, knowing I was pushing the safe limits. Is this from the lights or is more likely a nutrient/pH imbalance?

Hojas manchas marron The leaves of my plants have started to have spots, I've been told to spray them with potassium soap and neem oil at night, but it's getting worse each time. Could it be a lack of nutrients? Some fungus? Or leaf burns from potassium?

Brown Spots on Leaves I’m noticing some light brown spots on my leaves. After researching it seems that it was either 1) Manganese deficiency 2) calcium deficiency or 3) overwatering. I don’t think I’m overwatering. It could be the nutrients but would like input!

Bruising or nute problem?I do not have enough characters here, please check diary for details. Some tops are showing some problems. The thing is, only a few and it does not seem related to light distance. My first thoughts is this is bruising, but I would like some more expert opinions.
