Generally only use co2 if you're using HPS bulbs because of the amount of heat stress they put your plants under.

Co2 correlates with temperature not light conditions. 85-90 degrees F. 1200-1500 ppm co2

Is this Nute burn?
Is this Nute burn or something else? Using bio bizz grow, bloom and top max with “all in one” soil. I’ve recently upped the nutes in line with the bio bizz feeding schedule for my soil but it looks like the plant is freaking out at something. Thanks guys

Development issues
first time growing this strain, never had such a small plant in a 18L pot. She smells amazing, looks fine, but way too small. Didn't really used many nutes, or spent time around her, but on the other hand the northern lights next to her is doing great. Any thoughts?

Accidentally bent/squished the stem on Pheno #3, is it possible it can bounce back?
I was LST'ing the Purple Haze Pheno #3, I accidentally got a bend in the stem and it could have snapped or partially torn, I attached some photos hope these help. It was by accident, I have nerve damage and arthritis so I can't keep my hands still that much especially standing.

Why do my autos take longer than everyone else with same strain
If you live in a different part of the states or heavy LST make your autos take longer to grow. I see all these diaries that at 7-8 week there’s is not only way smaller ( I only have the diaries going now) and they are finished way sooner than when I have grown them. Thank you
