Ok guys need some Help i calibrated my control wizard 24/7 nutiernet meter, I have a 20 gallon res, filled with RO water. I added 20mls of Grow, 20 mls of Micro, 10mls of bloom, 15mls of cal/mag, 20mls of prozyme and 1 tablespoon of black widow and my PPM's are reading 18. How can this be? I have an air stone in there aswell
Edit.........
My calculations where way off, i just added more grow, micro, bloom, prozyme and cal mag. Will let it set in the res for a bit to get well mixed up its already shot up to 30ppm's
