I must confess that when I developed the original recipe I based
the %Mg and K on the Tropica formula. Since then I've reduced
the Mg to 40% of the original value and cranked the K way way up.
Because Tropica Mastergrow contains K, it's more than just a trace
element mix; however, my experience suggests that it has too little K
for us power growers. Using Mastergrow with supplementary K2SO4 and
KNO3 would probably work well for those who can't find a cheap
commercial trace element mix.
