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

What to do with fertilized colas
I've got a few colas that were pretty clearly fertilized due to an overheating issue weeks ago... is there any disadvantage to leaving them in? Would these seeds be worth keeping? (I seem to remember someone telling me years ago that this could create feminized seeds)

Removing "suckers" on autoflowers
I have these smaller growths on the lower part of my plant. They haven't really stretched out at all. I read that these smaller growths can suck available energy for the other buds. Can I cut these or just leave them and forget about them?

Location of grow
My outdoor grow is housed in a fence/building that's 12x12 and 8ft high.(See diary for pics). Since the trees have filled out they are blocking some direct sun. If I moved EVERYTHING over it would be a huge pain but would receive more direct sun. What would you guys do? Worth it?

Harvest autoflower so soon?
Auto Gelato from Ganja Farmer. Its day 58 and the trichomes are cloudy and the pistils are red/orange. The buds are beautiful and fragrant but still pretty small. Can she really be nearing harvest in less than 2 months? Is bud size typically lost in favour of speed with autos?

Stem Necrosis
So about 2 weeks ago (should have posted about it sooner I know) I noticed some stem rot on my plant. I didn’t know it could be the first sign of something much worse. Can anybody help me identify what the problem might be? Or any steps I can take to save my plant?

First time harvesting, I have been looking at the Trichomes and see a bit of amber but none on the buds itself. Any ideas on how much longer I should wait, also why are there so many white/yellow hairs if the Trichomes are already turning amber.

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?
