Hey guys I'm a newb here at icmag but have been a grower since the 80's. Mostly outdoors here in the northeast. And only in the last few years indoors. My question, I'm using v&b hard outdoors on my grow when should I stop using cal mag outdoors at 4 ml/gal. And go with strictly mag? I know it's nothing like flipping a switch but maybe 2 weeks after buds start to form
