Per gallon:
0.4g Monobasic Potassium Phosphate
0.77g Potassium Nitrate
0.05g Potassium Sulfate

makes
28ppm N
24ppm P
115ppm K

and ~2.5ppm S

Id imagine the N and K ppm for Hammerhead aren't 100% accurate, as this would explain the ~2ppm discrepancy that required me to use potassium sulfate to get identical numbers as the AN numbers. Im assuming that the potassium sulfate is completely unnecessary.

Ooops. Yeah its 200 gal not 757. I forgot to convert back to gal from L.

So you can make about 5x the amount of bloom solution going with salts for about 25 bucks instead of 40.

Tap h2o = 150ppm. Added GH3 @ 50%. Sea Green 1.5ml/gal. Hammerhead @ 2.5ml/gal. After this my ppm = 690. Once I started adding Moab my ppms would barely rise. It took more imo than the recommended dose to bring my ppms up to 890. My strain can handle up to 1000ppm max without leaf tip burn. My question is can I still burn my plants even if the ppms are within range using Moab?

And FWIW I max out at around 1.6 EC now. Anything more is a waste. Right now I am at 600ppm jacks/epsom/MAP and my plants are stoked.

Do you think EC/ppm has a correlation to the size of the plant you are growing? For instance, tree's should get a higher EC than say a 3' scrog.
