Hello community,
I am 3 weeks into my first grow. is it safe to use calmag this soon and if so, at what strength and how often? I know that I will have to start using nutrients at some point but I'm definitely paranoid.
Any suggestions are appreciated. These are my girls. I feel like they should be larger than they are.
