Droppy leaf’s

They are hitting their maximum DLI, essentially. now, is that after it repeats that process X amount of times or is it when that process starts, i have no idea on the nuance. the plants basically make themselves small to the light, "resting" in a way and less surface area getting hit by light. it's not the watering. it could progressively get worse, which would be more confident in saying it's beyond max dli. if there's not enough carbon (from co2 in atmosphere) it can't use the light. Other signs would be stunting or too tightly spaced growth nodes etc... if any vege growth remains. bleaching of course, but that can take forever in any borderline case. singed pistils - kinda look like little tiny yellow nubs. extra foxtailing. improved environemantal controls and boosting co2 to 1200 - 1300 ppm are ways you can give greater DLI. dli - daily light integral. good to read up on. it allows apples to apples commparisons of how much light is provided -- regardless of light schedule or size of garden.

No I don't believe you're over watering either, happens to me sometimes also. I think that the plant are soaking up all of the water and nutrients when it does this and when it's finished they perk back up. If you were over watering than they would stay droopy for a while before bouncing back.

I’m pretty sure I’m not overwatering as I usually wait until the pot is light and dry. It’s my first time using air pots, not sure if it’s related.
