I am certainly not a pro with indoor stuff but they kinda looked like a few I had when I had it running abit too hot. Just a wild guess for yours though. Any idea on the temps your running or have the air moving around at all?

Passive air intake intake fan setup to exhaust heat and pull air in. Temps 80-82 lights on night 70s small fan blowing on them clipped to tent out of pic view. Probably should get a decent oscillating fan.

Thought it might be calcium deficiencies even though Im already using 5ml calimagic per gallon.

Looks like edema, which is hard to control in hydro. If you have a non contact infrared thermometer, you can check leaf surface temps, which should be lower than the ambient temp, if they're higher you definitely need more air circulation.

Also, what are you nutrient temps like?

I have no hydro experience but recall hearing that mature, fruiting pepper plants like about 1000 ppm...

Yeah its this one where some experienced hydro growers (both kratky and dwc) talk about all kinds of setups and 1000 ppm
