Hi, I'm totally new to diagnosis, but I'm not really seeing anything wrong in those photos? Everything has a green shift though, even the planter. Might need to take a pic outside the tent in white light. Burnt tips, I think implies over fertilization though. I'm not familiar with coots mix, is it kind of strong? If so it might be overly strong for seedlings. I've run seedlings in a stonington blend that was a little strong for them, the first week or two they got burnt tips but they grew out of it. Other than that I don't know and hopefully somebody better can reply. Good luck!

Don't sweat the technique.
And honestly. My fuck ups turn to gold so much the thought of fuckin up don't even bother me. So I keep it auto when I'm stepping through a portal. I know that sounds strange but, strange beats normal.
