you have to use your own judgement on that ... personally, I can't even seem to get my ppm anywhere near the limits, Ive actually given up trying to get my ppm much over 1300 ... I grow a little different than most people, I just don't get too concerned with perfection (it's a WEED, and Mother Nature treats them like shit - they thrive, anyway) ... I keep pH within a 5.8-6.2 range, and if it drifts, I don't panic ... I seldom even check my ppm anymore ... so, LONG story short, I don't think 100ppm makes much difference, either way ... :jointsmile:
