How could YOU call it a Cal/Mag Issue.... With no F'N Picture?? And YES you can Over dose C and lock out the grow.The fact is that all strains are different, all tap water is different , all nutes are different and certainly everyone's growing environment is different to some degree, to say you don't need cal mag(especially in coco) because of whatever reason YOU don't need to use it is ridiculous. What if his nutes don't have much calcium, what if he doesn't use a micro nute that's any good , or one at all. Over dosing on calcium is very difficult, better he uses it to be safe then not at all
OP... Save this book and you won't see so much guess work.
