Sorry about the wait, I've been slacking on here. I use ff ocean forest with a buttload of perlite and about 2c of sprouting mix in the center of the pot so I can use 1 pot from seed to harvest. I use grow big at about 3 weeks from sprouting and I use big bloom with grow big as soon as I see pre flowers. I stop using grow big when flowers are established and after the last stretch. Cheers!
