Hello and thank you for any advice you might be able to offer. I’m getting some small spots and couple leaves beginning to yellow.
Plant is afghan auto flower
Went into flower 8/1 ish
2x6 tent indoor with 450w LED full spectrum light and CFL light.
Growing in soil with added perlite
I didn’t transplant in time so it is still in a 1 gallon pot.
Using fox farm nutes
Black Magic cal-mag
2 fans moving air
6in exhaust fan
Temp stays around 83 degrees
Humidity near 40%
Any ideas on the spots and yellowing before it gets any worse?
