lol i saw some burnt edges on fans so i said something. my guess is you follow bottle instructions, which tend to be a little hot. i liked mixing bottle ratios then adding ro water until i hit my target ec/ppm.
what style of hydro do you use?

i have so many strains growing i have to eye out most nutrients just by plant color and leaves, lots of experimentation going on also still perfecting my hydro, averaging 1/2 gram per watt .....Deep water culture is what I'm using
