I get that it should be concentrated. But personally using premixed salts I could never go back to liquids again. So much cheaper and far easier, plus I've only had one problem and that was with calcium for strains running past 10 weeks, an easy fix with just amending my soil mix.
Eta: if people can't even get bottled nutrients right, I agree they wouldn't be able to figure out raw salts.
I like Jack's Citrus ratios but have you ever calculated the actual cost of usage? 1.5lbs for $12 plus another $12 in shipping makes me wonder how 'cheap' it actually is. I see a lot of folks using 1 tsp/gal. That means a tub that costs me $24 only makes about 140 gallons of food. One teaspoon per gallon could be way more than I feed so maybe my math is skewed here.
