I'm running my first super soil grow . I use r/o water. I have general organics cal mag. How much should I add per gallon of water, what should my ppm's read after adding? Thanks in advance guys.

Each strain is different, some are cal mag whores. I'd start off by going 5 ml/gallon and adjust from there.

And as far as Ppm goes, read the supersoil thread. Sub doesn't worry about ppm.

But wouldnt I want to know if how much cal/mag I added was sufficient supplementation?

Read the bottle. Start with my previously suggested 5 ml/gal and adjust as needed.

I've been going all organic with blackstrap molasses every other watering. I'm growing Timewreck and so far so good. Save those microbes!

I'm doing 1 teaspoon/gallon of calmag+ in my RO.
