I would advise against mixing all three together straight. TMG isn't
close to a saturation point, it's little amounts of micros in solution.
I've never used Seachem K or Flourish Fe, but the website says K
is 40,000mg/L and Fe is 10,000mg/L. TMG has Fe at 700 mg/L.
Mixing the three may not cause any problems, but it just might. If a
saturation point is met somewhere, you'll have stuff falling out and
you'll lose some of the fertilizer. It may even clog a line with "salt"
crystals. If you add the three to water at a ratio of say, 1/10, then
they might stay together with no problem, but you'll have to dose
10X as much. I would try that instead mixing them together right
out the bottles.
