I hear that bro.. I have been using "sensi-cal(bloom)" myself, and also sensi-cal (veg), and I have to hit them with it every 3 to 4 times a week, sometimes less, depending on there leaf tips, or if I start to see light browing on the edges of the leaves. Most of the girls are cal-mag whores during flowering! I don't understand it either! It seems like to me that when feeding the (bloom) nutes, that would take care of any cal-mag issues, you know without having to add extra! One being because the bloom feed has cal & mag, plus tons of other nutrients that's suppose to tide them over during flowering, if feed correctly, and not to much!
