I'm impressed you master the art in repotting in perlite, just tried it once and she never got back to it. I made this in the transition between veg and bloom so it might have been to much in that stage with both Thrips and heat to battle for her.I probably should just start them in their final pots but nope. Always transplant 3 times. Just using least amount of light til they need it.
Now I let seedlings and clones root in small pots with soil and then transplant them to autopots with perlite and hydrocorn.
