i have...but ill do again.
let it dry till almost dropping. all the way to the center in bottom of pot. then make a batch of water pH`d to 6.3. keep pouring it through till the ruin off is at about 6,5 ish. let it dry again like above each time nbow. let it dropp if you have to so you know how many days. then next time water or feed the night before....or morning
this is a tropical and does way better on the dry side. keepin it wet like that is fukin with the cation exchange...which is pH the plant gives off basicly. theres way more to pH than what we do to our water or foods.
also being an auto back off on the foods they recomend,. they dont process as much as a reg plant and if light is weeker then it needs lower ppm also
