Could use a mentor

[Docnraq]

Looked over your nutes. As far as the stuff you dont have seems to be pk booster side. So to answer your question about necessity. No, I pk boossters not needed. Are they good to use, sure. But not a requirement.

The rest yes. How do those seedlings look today?
Also I spoke to my mentor about your spider mites.
Ill quote in his comments.

Captain jacks, and if you’re not in flowering, neem oil.
Honestly, I’ve thrown plants out if I discover they have them. It’s almost easier and cheaper. Just depends on the severity, and it’s an individual choice based on circumstances.
Example, one plant has them, I’ll toss it, to save 12 others, but I’ll treat all of them, because they do spread like cancer.

@Covertgrower

manageable at seedling size, because there’s so much less surface area to keep track of. Still hope for a seedling.
Due diligence will really help with treatment. If you don’t treat regularly and on time, you’ll get no where far.

I asked for suggestion for cleaning grow room? Bleach, insecticide, etc etc?

@Covertgrower

Both of those, and hydrogen peroxide (40% if you can find it) in place of bleach wherever possible. Seems like it’s not universally available, but if someone knows where to look, I at least mention it.
Isopropyl alcohol will kill adults, but not recommended on flowering plants. It dissolves trichomes.
