Rockwool EC spiking up

My EC has been rising drastically along with my PH when I check my run off. My question here is if im running a higher temperature due to running co2 at 1300 PPM, Would the plants be drinking much more than eating and if so is there any suggestions? Maybe running a lower temp or running a lower EC to help solve this issue. If anybody is familiar with growing in rockwool 6" pargro cubes your feedback would be greatly appreciated.

I am running a DTW hydroponics set up with my medium as 6" rockwool pargro quick drain. I am currently into my third week of flower and my plants are showing flowers fine but I know my root zone isn't in the best shape due to the salt build up and now showing nutrient deficiencies. I had just bumped my resevoir up to 2.0 EC from a 1.9 EC during transition and the PH of my solution is always at 5.8 .
