I just pop 5 gorilla cookies 7 days ago to fill my remaining space in my 4x8 tent. So 12-12 sint the start they all popped and all look good ! Cant wait to see it grow!!!!
I use calmag right off the bat. NPK nutes should wait but you're within the time frame where you want to begin. Start at a quarter strength for the kelp. Half strength of the minimum amount listed on your calmag.
Good luck!
