wasn't it Scarecrow in the Wizzard of Oz that sang "If I only had a brain".
Got up early and started mixing up the new nute soup. All went perfect until the end. I mixed my 5 gal of 150ppm Potassium Silicate (10 gr) and pHed it to 7.0 (160/500ppm total) Made up the Jacks 321 in another bucket, 2 gallons extra strong (4x). Mixed the 2 to a total ppm of 760 in the res, pH was at 6.1. All is good!!!
Then lugnut here added a full dose, 20ml, of GH Cal-Mag instead of the 10ml 1/2 dose I was suppose to add when adding the C/M, Orca and Hydroguard. CRAP!
I'm furriously collecting another 6 gal of RO! That will take a few more hours. Do I need to re-do the nute soup??? with the 1/2 dose of Cal/Mag???
