R u filtering the water?.. The constant rise in ph is coming from microbs in the water. Filtering the water helps a lot . Preventing light from hitting the nutrient solution will slow it down more. U can use black plastic sheeting. Check homedepot it cost around $10-15. U can also insulate the grow sites with styrofoam. But if you put the frozen water bottles in the nutrient solution make sure you take out the bottles and discard them if the ph begins to rise again.
