the CalMag dosage not critical.
I slop in about a tsp per gallon.
My Tap water is PH7.2 and ppm of 120.
The calmag takes it to about 250.
Then I add nutes to about 600 ppm.
If the strain no complain, I let the ppm climb until run-off is about 1200.
Then give them plain PHd water alternating with 1 tsp per gallon nutes to keep it there.
Only have to do that the first time with a new strain, and take some notes.
Then it becomes routine.

Aloha,
