hey fdd i notice you hang out in here, not sure how else to reach you but i got a quick question ... my last few grows i notice all at the same time, i get what looks like a calmag defficiency, it happens right around 4 weeks,and im almost on week 2 on my current grow, should i add a calmag supplement before it hits again at like week 3 or is the plant too young? also i never even used a calmag supplement before to try and correct the problem cus i didnt pick one up till now
