Ut oh..... When you bought your hydrotron, did you rinse the holy crap out of it? Did you soak it in a bath of good pH'd water? If not, this is your problem. THANK GOD my nursery guru told me to do this BEFORE I use the stuff, as you will have INSANE amounts of trouble with pH if you do not. If you go to the forum search button and type in hydrotron, you will see a few threads explaining it better. You are so early in the game that you could pull your plants out, and fix it. I recommend you do so, because if not, you will have a battle on your hands. All that red residue on those clay pellets needs to be rinsed off heavily (garden hose). I then used like a 30gal tote to soak them in at a pH close to 5.8 and such. You may need more then one soaking.. As you will see the pH rise in the bath..

Ok 2nd! I dont know anything about GH nutes, so hopefully someone else will chime in.. BUT.. I use fox farms, and my ppm in the very beginning was 400. When you add pH up or down to your resevoirs, or anything in the matter that isnt clean and fresh water, your ppm rises. ppm is parts per million, and it measures the metals in the water, the concentration of them. The more additives, well I think you get it. that meter should be fine.. i dunno. Yeah when mixing a batch of nutes up, add one nute to the water at a time, stir, then pH. Checking ppm after is a great way to see where your at. Im not as good on it as I should be, but every other day, checking ppm, will tell you how much your plants are intaking in form of nutes to water ratio. If the water level in your resevoir goes down and ppm goes up, its taking all the nutes it can, but its mainly just taking in the water. If the water level goes down and ppm goes down, thats great! means your plant is taking water and nutes at the same level or so. One thing I just learned though, if that is the case, when you top off, top off with a nute mix because if you dont you will dillute the resevoir even further.
