Hey folks, so I’m wondering peoples ideas on feeding cal mag in soilless. I like
To keep my pH from 5.5-6 but cal mag is better absorbed at 6.2. Anyone have any knowledge to pass along?

Thanks in advance.
 
I've been running 5.8 from seedling to the flip. Then 6.0 during the flip, and 6.2 from the appearance of first flowers until harvest. This has been working well for coco/perlite.

And do you have any issues will cal
Mag and the pH?

One strain (Sapphire Scout) required a little more CALiMAGic than most, so it showed signs of deficiency that I corrected with the next feeding. There's no formula that works for all strains. The pH never presented a problem with any strain I've grown.
