I use quarter teaspoon of fertilizer per milk jug alternating with 25-10-10, 20-20-20, 10-52-10, calcium nitrate and Epson Salt each week.

BTW is that a qallon or 1/2 gallon milk jug?

Interesting how different people have different luck with different media. My Phrags seem quite happy in a mix of CHC/Diatomite/Sponge Roc. Been using it for 4 or 5 years.
Well wait and see how the knew K-lite feed works with your CHC.
Remember that CaNO3, and MgSO4 are just 4 of the primary major cations and anions that make up 99% of the "salts" that we expose our plants too. Of the other 4, Na, K, HCO3, and Cl, K ends up as the most common, and most influential.
So in the case were you "condition" the CHC to drive out the "salts", you set up an ion exchange system, so each time you fertilize,the CHC gives back the Ca and Mg, and sucks the K back up (we always use sodium free water, so K is all it gets to take). It doesn't take too long with 100+ ppm doses of K in our fertilizer to kick out all the Ca/Mg that was used to condition the CHC in the first place, and before long your CHC is even worse than when it got washed with sea water in Mexico!
Would 20-20-20 general purpose fert be OK? I get it from the earlier post that 1/4 tsp for 4L would be the concentration, right?
My CHC does not come from Mexico.
