I had some old Miracle Grow soluble fertilizer, and watched a few youtubes. Basically the recipe was add 2.5 tablespoons Miracle Grow, 2.5 tablespoons Calcium Nitrate, and 1.25 tablespoons of Epsom salt to 5 gallons. I did that - I used tap water that I added some sodium thisolsate (or something like that) and a little vitamin C to dechlorinate it.
The mix looked ok, nothing came out of solution or anything, and it has a nice light blue tint. But I tested the PPM and it came out over...
So, just mixed up a hydroponic solution - 2,800 PPM?!
