Yes! Use calmag with every feeding and watering. 1 tsp per gallon of water. And yes you can mix it in the same water as your nutrients. Just make sure you ph AFTER adding mag and Nutes.

Funny, that’s how I always do it and never meant to do it in any particular order.
Every water Minus some flushing with no nutrients?
Appreciate it

Its my first time using RO Water. Im using 50% sphagnum 50% perlite.
Didnt plant the seeds yet.
should I use Calmag even before the seed sprouted?
If not, should I water only with pure RO water?
My RO water here is 3ppm so my concern is the ph and the lack of essencial nutrients.
I did read something about buffering the ph of RO water but it was a long time ago.

Sorry. Zero experience with sphagnum.

RO and distilled water requires calmag due to their lack of Ca and mag in the water.

I personally use calmag from seed to harvest. Well let me rephrase that. 2-3 weeks prior I cut it out. Usually 1 tsp per gallon of water. So if you don’t have that many plants to water, don’t make a gallon of water with calmag in it unless you plan on using it right then. With a seedling you won’t be watering that often so the water will sit there for a while until you use it again which you don’t want.
