You can't drop your humidity and raise the temperature. Cultivate the top of your soil but be careful not to touch the tender roots or stem. And get some wind blowing around over the top of that soil with a oscillating fan. And DONT WATER THAT FUCKER TILL YOUR POT FEELS LIGHT TO PICK UP :)
I like when plants fuck up like this. It's a fun challenge to do what i mentioned and see if you can bounce her back. It's great to just grow for yourself and not for profit because there's a i don't stress about killing plants attitude that comes with it, It's nice.
