You stop foliar, not cal/mag. A lot of people stop or diminish cal/mag supplements because of the nitrogen. If your growing in coco try supplementing with epsom salts for mag and use calimagic every 3 to 5 days till you flush. Plants need calcium throughout their life cycle. But you can stop ca altogether and just use epsom.
can i just use botanicare cal/mag week 3+ in flower? ill use foliar up too week 3 in flower and can i use it till the end of flower?
It all depends, are you growing in coco ? What stage of flowering are you in ? 1250, 1450 until week 4 is fine. Then id drop in increments till week 6. The strain and finishing time is a factor to consider aswell if your growing a 11 to 12 week strain you should adapt accordingly. Ps... remember to flush ! Best of luck.
Ahh! Apologies I'm in soil with coco and I'm in veg week 2 on Charlotte's Webb.
The Heavy16 prime has calcium and magnesium . So technically you don't have to suppliment once you stop foliar.
Sorry my stupid mistake - foliage feeding should be done 1 x per week at most or at least in week 4 of veg (make sure you don't over do it) also make sure you spray the undersides of the leaves that is were the up-take - take place thru it's (plant's) "stoma's"
