calmag not needed yet - but what is a- is a good root stimmulator - start feeding cal-mag at week 3 in veg (1 -2 x's a week) - in flower stage for 1st week - that's all !!!!! --- many get "n" toxicity " with cal-mag because of over use (leaves that look like claws = "n" toxicity") Plant looks good mist only 1 time a week or so hitting the undersides
