Hey guys, im having some issues on a couple 3 weeks old plants. I dont even know if its toxicity or a deficiency. They are growing in soil, temp and humidity are good, but I dont know what is causing this. The lower leaves are turning from nice green to dead leaves in 1 to 2 days. I started feeding a week ago

Yeah, im growing on soil, and no, I don't have any perlite in them. Last grow went wellicht without perlite but yeah mixing with perlite is def better. What do you think causing those leaves to die that fast?

I just think the soil looks funny with no aeration and it could help a lot to add some perlite or other kind of aeration to it. That could cause the yellowing. You probably have to give more info about the plant strain and what's in the soil mix and what kind of nutrients your giving and how much.

You need perlite($6 at HD, $8 at WM), your roots cant breath. Judging the pics, your soil is getting realllllly compacted and theyre suffocating. When you water at this stage, you want to spray it in as opposed to a gentle pour

My guy mixes his own soil and its usually 40% perlite.
