Does this look like over watering or heat stress?

Looks like heat stress. Might be a lil nutrient lock out too.

Hi guys I do have a swamp cooler but it packed up a couple of days ago so currently have 2 bowls of water and a bowl of water infront of my intake fan had an exceptionaly hot dry spell recently but rained hard today and rh has risen back to "normal" for my area will order a new cooler this week tha ks guys

30 isn't too bad. I run air conditioning in my lung room to keep the max at 29 and occasionally it hits 30. Above that and your growth rate will slow but the plant will be OK. I don't get concerned until it hits 35 or more.

Looks like heat stress and water damage. Open up the tent, get better air exchange, they don’t like super high heat.

Spruzzare le foglie non aiuta molto con l'umidità ma con quel caldo potresti bruciarle...Non hai umidificatore? oppure metti stracci bagnati attorno

Hi, I believe it's a simple case of spraying your plants with water, thing to remember is water acts like a magnifying glass and once settled on a leaf it will intensify the light being emitted through the water, if your trying to raise RH and do not have a humidifier then dip a towel in hot water and place the towel infront of a circulation fan, this will raise the RH for a short period of time, but not good if your struggling with temps, hope this helps
