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

Rusting leaves?What can I do to remedy this? Is it a calcium deficiency? I’ve been adding 5ml of cal/mag to a gallon of water, can I add more? Will the grow dots suddenly release lots of calcium? I’ve also top dressed with natures living soil flower power and worm castings.

Will there always be fresh bud growth on an auto-flower (max thc/no couch-lock goal)?ready for harvest bc most of the pistils are mature? Clearly not yet because of new growth? The trichromes are looking like a mix of clear and cloudy, little to no amber yet. I would like to know if there will always be fresh pastil/bud growth even when she’s ready for harvest?
