So.. Some dummy got the calcium nitrate wet. And the Epsom salt. I am used to adding it by gram. How do i do it by ppm?

Ppm for calcium nitrate and epsom

Good question. CaliMagic seems to be about 150ppm of N/Cal/Mag. at 1ml/L from memory.
I've been doing fine with regular doses of CaliMagic 0.5ml/L with food and 70ppm of epsom to cure LED sickness. On top of base nutrients/feedings of course.

So 2.5g per gallon gives you 350ppm? - the 20

Anyone else confirm something similar? I have to do Epsom also.
I guess you could put 2.5g in and measure how far off 370 you are. That's your conversion rate for wetting it.
Same for the Mg. Put in a know amount. Calculate what should happen and measure what actually happened. Conversion rate found.
Yeah... sounds easy but somehow hurts real bad
Edit. I don't have a ppm meter. I would weigh out 10g and bake the shit out of it until dry. Again, it's your conversion rate.
edit2: Phostrogen is hydroscopic and turned to mush. I dried about a kg in trays. The inside of my oven is now crystaline. The glass door feels like sand paper. Phostrogen only costs a tenner. The oven.. a bit more. Stinks bad to. Be careful. It's likely toxic to boot.
