Discoloration of leaf think it’s a bug

For sure check underside of leafs, but what I see and Im think its from watter drop. Spray plants only when are lights of, these drops can be like magnificiant glas.

It is probably happening because you are spritzing your plants unnecessarily. Dissolved salts in the water burn the leaves once the water evaporates. It is not a bug issue.

don't worry. nothing dangerous. such cases often occur due to the fact that the leaves touch each other and burns can occur between them. don't worry. everything is fine.

It’s all organic I don’t ph water or nothing just air stone pump in the water for 24 hours before to kill chlorine and microbe in soil take care of rest maybe the soil is a little too hot thank you

Hard to say with your picture but highly unlikely its a bug. My guess is PH burn from being out of range.
