New Grower

Quick question on ppm.... We currently have 2 plants in aeroponic system. Currently in week 3 of veg. The first week our ph and ppm were perfect. The next 2 weeks the ppm is going up by approx 50 every day. We tried lowering the nutrients on the last water change and the ppm is still slowly rising. Plants look great, no signs of stress. Growing well and happy. I'm just worried that I'm just not seeing a problem. Any advice would be appreciated.

What is your water source? In my area the snow melting from the mountains will dissolve ions and this is enough to raise the pH by ~1.5 and ppm by ~200 up until mid summer. Then it goes back down to near ideal levels.
