Guess on what this is?

Looks like a straight up calcium def bro cal and mag def go hand in hand just top cal mag every feed brah and you should be sweet as your going through this stage of flower you have obviously upped the light intensity as you should but the closer the light the more it burns through its chlorophyll easier amd cause she is in flower you up the p and k as you should but more o and k means the harder it is for the girl to take up cal and mag so you need to up the cal mag that's all but you should be close to flush and harvest soon so not really to much to worry about just a heads up for next time brah keep up the good work brah
