Drooping leaves on one of my plants

2nd grow ever: 8 weeks into vegetative
-spiderfarm 1000w led
-higrow 600w led
-ff of soil
-ff trio plus: fish emulsion and gringo rasta cal mag
-strain: pineapple express by Amsterdam marijuana seeds

My leaves are drooping on my larger plant! Its starting to concern me. My initial suspicion is that there's too much light. Had been using the higrow 600 w led initially but just installed the sf1000 about 4 days ago. Both lights are about 18"-23" from canopy. Anyone got anything? Many thanks friends

*edit i keep my room around 82ish.

What is the white stuff on the leaves? Are you sure you don't have any pests or early stages of powdery mildew? BTW, putting your temp/humidity sensor on top of the soil like that is going to give you readings that are useless to go off of. It's going to be measure the temp and humidity at the soil level instead of at the canopy level.

I sprayed a baking soda+water solution on the leaves because I suspect some fungus early on. I do it every once in a while to keep rusting at bay. Seems to have worked. There is a powdery residue on my fan and humidifier. But only one plant is affected.

Also my environment monitor receives input from the sensor hanging above the plants, cant see it in the pic
