I'm old and can't remember if you're growing in soil or coco (hell, what's my name again?). If soil I wouldn't use much if any
calmag. Careful.
Itās weird plumber I never used it before.
About eight years gorilla growing and 3-4 years high pressure sodium . Iāve done 4 grows led now as circumstances are difficult would have been more prolific as before.
I like to understand things and they need more calcium under these lights (my ones anyway). Have played with tweaking it and although might not be sweet spot, itās visibly better.
Every time they have not had it in feed every couple of feeds I get cal deficiency. Iāve grown much more with hps.
If you need an indicator of how much itās I was aiming for total organic grow.
But couldnāt see my girls living with rickets, there is now organic calcium additive so if I can justify it with all nutrients I have I will try.
My roses love the cal mag anyway itās like little shop of horrors though āfeed me Seymour ā
But they return the favour
