I´ve had a lot of fungus gnats on that tent (have been too lazy to put some diatomite there, and mosquito bits have not helped), but I don´t think that´s it. I would have thought about the air pockets before, but after so many waterings and a transplant it does not seem likely.
Nah, just a new batch of perlite-rice hulls/vermicompost/peat that I ammended (kelp/crab shell/neem meals, basalt sand, oyster shell, gypsum) late last year, but seems to have been hexed from the beginning. At first I thought it was too hot, but now I believe there should be something else. To be honest, I could have been to effin stoned when mixing the soil, so I could have forgotten something or added too much of anything
These are surely the worst looking plants of the run (aside from the fact that they were a mutant and a runt from the beginning).
