cal mag please help

hey guys the end of my leaves are getting yellowish brown spots so do you think i should invest in some botanicare cal mag plus to start adding to my nutes, does anyone have any experience with this and does it work good

Are you growing hydroponically if so you only need cal mag if you use water that is prepared by reverse osmosis

I use Cal mag and Liquid Karma from Botanicare

If the yellowing is starting from the top and working its way down, then its probably magnesium, and magical would help.

If your ph is to low however, your plant cant absorb the magical, so make sure you correct any ph problem before adding it.

Best of luck grower<3
