This is going to be my second grow. I have two super lemon haze germinated and put them in soil last night. Since my first grow I have bought a ro water system. I understand that with ro water it takes out things my girls are gonna need to thrive, like calcium and magnesium. I bought some Cal mag to add to the water to balance it all out. My question is, how much Cal mag should I add to my water for seedlings? Or should I stick to normal pHed water till the hit veg stage?
