i,m using pure blend pro bloom/grow/calmag plus (not all together). when i flower i will do 15ml bloom/5ml calmag plus. when i have my mothers and veg going 15ml grow/5ml calmag plus is this right? also how do i do the add back with pure blend pro?when you have micro you double to get your bloom addback. how do i do it using pbp and calmagplus.
