This is a Super Skunk in week 2 of flowering. Now the fan leaves are having issues. They are also drying up as you can see in the picture. I only using compost teas and organic soil mix created by me.
With that temp Im going with underwatering. 66f is nowhere near too hot. Whats your watering and feeding schedule?
I don't know but they look pretty weak and burned. You might have burned them with the "tea mixed by me." LOL They don't look like they're so bad they can't be brought back out. Do you manage the pH of your water/nute solution? TWW
