!/4 retarded

We notices spots coming in on the leaves, we didn't have a good explanation for it so we did a runoff and found the PH down in the 4's. So we did a complete flush and go the PH up. With that we finally pulled the trigger and are going to buy a PPM meter. New dehumidifier is working like a champ and bringing down the RH. We also made a new DIY light using Samsung Q series 2' LED strips. We did it with a mix of 3000k and 3500k strips (10 total). The driver is adjustable from about 20w to 240w, we are keeping it at about 200w for now. There will be some more of these being built in the next couple weeks, this is the first attempt at a DIY light.
