I'm struggling as I try to get my head around the differences in nutrient dosage amounts between the labels on the bottles & the published feeding chart. I'm using 12-13 gallons of water in a rdwc & separate dwc systems. If I use either suggested dosage amounts I fall woefully short of the target ppm provided on the published chart. For instance... I'm feeding for WK1 Trans/Flower & using the bottle recommendations I am only arriving at 565 ppm while trying to reach a target of 1550! So... I've doubled, then tripled, the dosage amounts for all nutrients (Silica, Base, Grow/Bloom, Vitamino, Fulvex, Tea, CalMag & Hydroplex when in bloom). Even after tripling the bottle dosages I'm still falling short of 1550, by a long shot. Have any of you had the same issue? I'm also using their HydroGuard & some Great White to keep the root systems healthy.. but, I'm still falling short of my goals. I'm following their instructions but I'm not arriving at their target. Should I be supplementing with other ingredients? Any info you could share would be greatly appreciated. I'm a new member. I did search the forums for any related content. If I missed something, I apologize.
