Could be damp soil, not enough oxygen to the roots? Anyone else got any ideas?

What kind of soil are they in? Did you mix in extra perilite? Could be a drainage issue?

That’s why I like my bottom feeders, if I water from the top I’ll still get drainage to the bottom.

I've been watering from top and bottom should I just water from the bottom?

I have no idea I keep the temp in the grow space at 70-75 degrees though how do I check the soil temp?

well I haven’t seen a difference from watering either way, I find watering from the bottom promotes root growth towards the bottom of the pot, I’m watering from the top on this feed to aerate with peroxide, but I like to water from the bottom to make the roots search for water, instead of just spreading around the top, because once they have hit the water source, they will spread through the pot, and the more roots I get the better, but I want to make sure mine get down there, because that will promote large growth and extra oxygen into the roots because of air exposure. Thinking a little more I will want to watch for root rot and mild on the exposed roots.

I attached a pic of the soil I'm using. I haven't added anything extra so far just water is all I've given no nutrients/fertilizer anything. How do I go about setting up a better drainage system all I know about that is having wholes in the pot for the roots to breath. As far as that goes I may have no drainage at all.

I water about 350ml half and half bottom and top how would I go about getting more oxygen to roots?

I would suggest 3% peroxide, and then figure out the ratio of peroxide to water for how much you use to water, it will aerate the soil, add oxygen to the water, and also eliminate dead roots, and fungus.

He's asking what the pH is of the soil. You should be aiming for around 6.5. Get a pH soil reader

I'm a beginner as well but I know roots need oxygen. When you go to re pot, maybe try something like some fox farm happy frog and mix in a little extra perilite. I'm just speculating though dude, don't quote me on anything. It's really hard to diagnose anything from just a few pics
