Help with PPM on General Hydroponic Nutrients. \t\t\t \t\t\tI am having some problems understanding PPM. I am using the General Hydroponics nutrients with a HM Digital PPM Pen I'm using General Hydroponic products and going off of their Expert Flora Series (look at the attachment). This is what my local hydroponics store told me to do. I'm using a 10 gallon res but only filling it with 3 gallons.( I change water every week and clean the tubs tubes etc) The PPM readings I am getting when I stick the meter intothe one gallon jugs I use to fill the res up are showing 150- 163x 10ppm . I'm kind of confused on ppm because I'm literally doing what home grown told me and taking the nutrients and dividing it by 50% In Each one Gallon Jug I mix up the following for Bloom 4ML of PH down (water system sucks and my hand is too messed up to carry jugs.} 3ML of H202 2.5ML of Flora Grow 5ML of Flora Micro 7.5ML of Flora 4Bloom 2.5ML of Floralicous Plus 5ML of FloraBlend 5ML of Flora Nectar 2.5ML of Liquid Bloom my water before Nutrients is at 360-375 PPM PH ends up right at 5.9 to 6.3 PPM ranges 150-160 x10 I'm Following the same directions of 50% for the seedling phase of the flora series that is in the attachment and I'm getting PPM's of 630-670. Super Confused.... I really do not understand if I was told to use 50% and I"m getting that high of a ppm???? Any advice will be greatly appreciated.
