All I use is the a&b, silica, hydroguard, dripclean, photosynthesis plus, and add bloomsap in flower. And pH down. That's it. And been topping up with just the a&b without anything elseI’ve eye balled there kit a few times cause if I do it think I would want to use the whole line..
The one thing I didn’t like was they have a flush at the end of the schedule but I didn’t pay much mind to it
