Growth has really taken off. As such I've increased their nutrients, dropped the pH a bit, and have also turned up their temp by a couple of degrees. They appear to be thriving, but I've noticed a few spots on some of the very large fans. Any help would be appreciated.
Hi growmie.. do you use trace elements like sulfer .magnesium.copper..zinc.etc.. they're trace minerals because plant uses minimal amounts but it's needed. ...does the spots look like rust spots could be the first sign of a salt build up ur about to have nutrient lockout... If it gets worse flush it with spring water for 2 days( over water ) then allow soil to dry out completely then resume nutrients.. you don't have to increase strength of nutrients but u can feed more often with less nutrients.. full nuts every 4 days switched to quarter nuts feed every 2 days is better it minimize the salt build up.. ... Have fun B safe🇯🇲growers💚growmie
Everything is looking great on your grow to me but the strength of what your feeding anything over 1.2+ ec is high for autos..
I also think that issues on the leaves maybe a pest. please check the underside of the leaves with a magnifying glass and look for mites or eggs.
not 100% convinced its them but I would want to be cautious on it.
As for the feed use this link. it does a great job breaking down the requirements for autos.

Autos feed less then Photoperiods and I think all mephisto genetics are autos.
This is not set in stone some will need less some more.
Best Of Luck and Happy Growing!
