ok- how far from light? temps... o u said. I'll go get the fool's translation. that 600w, the shock value, or actual, burnin watts- for instance, my sucker lights r 3000watt led's, but they burn 600ish n that's the value, in question. could explain the lower, outshiners. um... also- inferred n ultra... will burn watts, but the nood eyes, won't c em so there's that, as well. lemme take another look... u need those ph and ec/tds values- every feeding. i check, at least, daily and i know n my heart- i could ignore em, for 3 days, but we're gardeners, now so we check, as often as is logical. i make mistakes, all the time so... daily checks, keep memory n check. um... can't continue, without those figures. i think you'll find, u won't get far, either. zerowater filters, come with a tds. well water, while fantastic!!! can impart values to ppm/nutes u typically may not want, or at those lvls. some nutes r made, specifically for highly mineralized, h2o. I've not used them. far as trichs & when- buried deep n my pics/pic summary- there r um... trich maturity images for varying stages. u might take a gander.
