Pest Spray has burnt my leaves

[Rusty Trichome]

It's been very very hot and I think my bro sprayed some water on the plant during the hottest part of the day which obv didn't help things!

Let the plant hydrate herself. Spraying while heat-stressed, adds stress. Keep the rootball (pot) shaded with cloth or boards or something, but allow for air movement around her. (shade cloth should work)
Don't overwater because it's hot, but make sure she doesn't run the soil completely dry either.

1st grow and a little obsessive lol

Hmm...that's unusual. :jointsmile:

Go easy with giving nutes every 3 days. Start at a lower dilution rate, (1/2 strength?) and adjust if needed. But form a schedule. Guesswork can and likely will kill your ladies. Always measure your nutes.
