HELP PLEASE DWC Grow ph and ppm steady rising

My temperature is about 86 degrees in the area i have my dwc setup and it seems like every hour my ph is rising have no idea whats going on one second i check its at 5.8ph then its up to 6.4 and the ppm is rising. any help would be nice thanks

you don't think it is the temperature? It seems a little high. I don't know man.

Well its my first go at growing thats just the outside temp
not the res what would be optimal temp?

Are you using hydroton rocks? If so,they should first be soaked in ph'd water.Soak them overnight in water ph'd at 4.0. This should lower the ph of the rocks and help stabilize your resevoir to where you need it.

are your plants taking in alot of water? it sounds to me that your plants have plenty of nutes and wont take in anymore that is why your ppm is riseing,as far as the ph what are you useing to adjust it?

Need to keep the water temp at around 65 degrees, until you do you will see problems.

Yes I am using hydroton rocks that may be my problem I didnt soak them in ph water and they are not takin in much water they are still young a week out of the cloner roots are looking nice and long thanks for the help got temp down in the room to 75 degrees
