Idk if I should bump up the ppm this refill or stick with the 550(approx). Monday should be my refill day and my ppm has went from 550 dropped to 515(approx). The colors look real crisp and nice grean healthy no droop whatsoever. So maybe stick with this ppm mix until show signs it needs a higher dose?
