Weird Sugar Leaf BurningDoes anyone have an idea what happened to my leaves? They are trying up and burning for some reason but only 3 of the 7 that are in the tent. They are all clones from the same mother plant. At first I assumed it was too much light at 1200 ppfd but dropping it didn't help.a year ago

Slight leaf tip "burn"What do you think is causing this burn on my leaves? It seems to be quite common. and maybe nothing to worry about if it's this minute. but I would prefer to not burn my plants at all if possible. Could it be a sign of underwatering? Light distance? i have a dimmer keepin at 1000a year ago

Leaf tips browned. What nutrient problem is this?Leaf tips browned. And some signs of burn/discoloration at the leaf side edges.
Do you think it's general nutrients overdose? I didn't increase my PPM for the last two weeks, so I don't think it is a problem...
Or Potassium deficit? Or any other secondary nutrient deficit?Leaves. Edges burnt
