I thought it was fungus but like I said when I scratch it it doesn't come off and the scratched place reveals plant material underneath as if it's the plant. I ripped one of the rockwool cubes open and I have fungus gnat larvae too so idk.
I also thought that because it kind of looks like knuckling formed by extreme supercropping but these are obviously not extreme supercropped. They don't look damaged in any way.
Not sure I understand. How can you get root rot without roots? They do have a decent amount of roots now though. Nice white fuzzy roots.
you think so? i use straight IBA-K and don't get that
Yeah, it's a classic response to some rooting hormones... It's just another way the plant is expressing it. Like the heavy, thick stems that they can get also..... Some have mix's and I like to use one I make my self with a rooting powder and Willow water...... I get big bumpy fat stems on the lower part of the stem and it goes up, into where they weren't treated too...
Thanks Doc! Yeah, I don't know what rooting product was used.
I think I just fed them. But could explain why I found a fungus gnat larvae. I've been letting them dry out so they are very dry now I need to go feed them right now. As well as hit them with some h2o2, and dunk them to get rid of the thrips.
