According to a chart someone recently posted here, the plants' need for cal mag drops in week 1 of flowering, and again in week 4. Unless you have a cal mag deficiency, you shouldn't need more than 2ml/gal at this point.I’m running general hydro nutes at 80% , ran into a deficiency week5. What do I run cal mag at without getting burned also how long all throughout growth ?
Throughout the whole grow ?!i use 2-4ml / gal
yep. they get cal-mag every time i water at that ratioThroughout the whole grow ?!
