Hm.
Strange.
As asked above, yes, I have a fresh container, and the one I'm currently using has only been opened for a couple months, but has no evidence of any moisture at all.
Ever since I got it, the few times I have used it, I first tried 1 tsp in a cup of water stirred for a few minutes, then dumped into my gallon jug that I use to shake, then into the plant.
Most of the time, I'll pour the cup into the jug, shake, pour a cup back into the measuring cup to stir again and try to get more of what's left still powder from the bottom of the M/C, and do that 3 or 4 times and I still leave shit at the bottom.
If I just add a tsp to a gallon jug and shake for a few minutes, I leave a whole bunch of it at the bottom after I pour.
Just getting tired of this, since when I mix MG or any other 'water soluble' ferts, I don't have such an ordeal to dissolve everything.
I guess I'll open my second container that has not even had the lid removed yet, and try that and see if it's any better.
Oh, forgot to mention........ this was all with room temp water, so the last couple times I tried nuking a cup of water to about 100 degrees, and that didn't even help.
