I've never had budrot spread indoors or outdoors. Not uncommon for me to grow 4 plants in the same pot and only 1 will get rot outside. Only had rot once indoors and it didn't spread to the other plants. And I've never caught it early enough that it's white I've used ozone with plants in the tent and it pretty much took the wax off the leaves and turned them into paper
Shit.
This doesn't look good.
I think we can basically sum this whole thing up with "I'm a bit of an idiot."
