How much cal mag do you use and when?

They are already flowering but I have them FFOF soil that’s why I’m afraid of feeding yet

Ull be good. If they r flowering id start with the flower methods. U use gh right or jacks

Idk what that is I only have cal mag and the FF trio


This is how they are so far at 4 weeks with no feeding

On this grow I used ffof and ph water. I know if I would of feed her what she needs my yeild would of been better.
