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

Should I be worried about my plants looking so droopy after dark period?
I am running 20/4, after about 18 hours the leaves stop praying, gradually start to droop until it's worst point through dark period. When lights come on, I water them, within an hour they perk up. Humidity drifts up around 10% during this time also and temps down 6-8 degrees F.

Seed struggling to germinate
This Mango Skunk by Nirvana has been germinating for four days. Should I give it more time or give up? The other 3 seeds (different strains) germinated in the first 3 days without problems.

On week 10 of Autoflow, stop feeding about a week ago. buds are looking like they might be done but are still skinny. Was going to wait a day or two then do a day of darkness. does this sound about right? should I have feed longer?

At week 5 of flowering, I've read guides but all strains are diff. Does it look like it's time to start flushing 2 weeks and then chop?
I have 4 different strains in my tent with different needs. Next time, probably keep it to one or two strains. Does it look like time to start flushing the plants in the pictures? Having never done this, I don't know how long I can let them fatten and how to time it. Thoughts?

No smell before harvesting the plants
Some plants will be harvested tomorrow. I remarked that the smell is not as strong as a few weeks ago. I smelled them at the beginning of the run, so heat was not at the maximal point.What could it be: heat? fertilization (plants ready to harvest are not yellow but nice green)?

Harvest time or wait a few days?
I think I'm going crazy but they almost look clearer to me (the trichome stalks especially) than they did a few days ago. Is it depreciating, or is this what happens before they amber up?

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?

How is she looking?
Honest opinions please I've not had much time to keep a proper diary on this one but I feel like I have almost cracked this strain. She was slow for a couple weeks after transplant but no real shock. Now in mid flower How does she look and what could I do better?

How close to harvest?
This is my fourth grow and every time I'm doubting myself when I should chop her down.Can I get your opinions? All microscopic pics are on the buds and not the sugar leaves. To me it looks like I'm close, about a week? If I'm off a lot in my time can you explain why? Many thanks!
