microgrowery

Your might considering looking into perlite as an additive. Your soil looks very compacted, cannabis prefers a bit looser mix.

It's not a huge plant yet, and since the soil is so compacted, it might have trouble getting roots through it all.

Perlite is like very light rock material you mix into the soil. Vermiculite is another. You can do a 5050 mix and that's what a lot of hydroponic setups use. But just adding perlite to coco/soil is fine as well. It's just that the market gardening oil you'll get is usually a little too compact for small time indoor farming for cannabis like plants.

Ideally you'd water the entirety bucket until It drains a bit then wait for it to dry or be drunk, which for me is usually a day or two at the point where I'm putting them into flower.

The lighting is only one trigger. Other environmental factors affect it. Like if it's still a bit of a immature plant, not ready. Or if there's high nitrogen.

Usually it takes about a couple of weeks from when you flip the lights until you start actually calculating your flowering days (ie they properly start budding.)

Happy growing.

Edit reply to me tomorrow if you want photo examples now my lights are off plants resting
