Hello.
I want to start 4 plant autoflower grow soon and i have question about soil.
Will soil mix like this work ok:
''25% perlite
25% vermiculite
40% peat moss
10% worm castings''
?
And how high should ph level be?
Sorry for noobie questions.

That mix will be considered hydro and not soil. Soil runs a ph between 6.5-6.8 and hydro runs a ph between 5.8-6.2. I would also reduce the vermiculite a bit and add in more peat moss
