Planning to add calmag to my regimen this grow so how soon should I start and how much? Just transplanted this week. Soil grow FFOF in 7gal fabric pots. Input would be appreciated greatly!
I start giving a little CalMag with their first watering after they sprout as I use RO water.

My tap is around 300ppm on adv and ph 7.3/7.7. I ph down to 6.5ish.
With ocean forest, I didn’t start until I needed to start feeding regular nutes or if I was using RO water.
