Question about length of Calmag Usage

[Cannaburg]

How late in flower do you wanna use calmag... I here around week 3... or at the switch of flower....

Your thought???

Right up until a couple of weeks before harvest.

What medium are you in? I'm in coco and I'll go all the way through flower. The amount peaks through the second half of veg then steadily drops off week by week throughout flower such that by the end of flower it's a very small amount: 15-25% of what it was getting in veg.

You can use cal mag anytime but it loses its effectiveness the later in flower you get. The stuff it provides to the plants is far more active in early weeks than say mamoth which you start slow in flower and go heavier towards the end. Plants are developing and doing different things during early and late weeks.

i use it all the way through, just change the amount as plant needs change.. calmag is important and needed right up until harvest..
