Ph rising every hour help plez

Hey guys,

So I took my clones and I put them in my dwc, I go down and check on my little ones ever couple hours or so. It goes from 5.5ph -6.5ph some times up to 7.2+ph depending on how long I let them sit there.

20 Gallon Rez 1.5tsp of each flora bloom,micro,grow Then set ph to 5.8 and ppm was at 120

Rez jumps ph after couple hours and ppm is holding 160ppm, I don't let the ph go above 6.5

Here is my link to my Journal where you can see my set up and my baby's
