PH Keeps Rising

[TokerToms]

I always do a ph check before I Watering. Even if I havent added anything the Ph can have raisen from 5,50 to 6,50-7,00 on under 12-24h.

Short info on setup: aprox 10x10 feet grow tent but I have splitted it in 2 so when theres dark in 1, its light in the other one, Using coco bricks that I soak myself and using Canna A+B series. Right now im in seedling/early veg.
600W on a 4,0 Lightrail, 16x60w LED and 2x co2 Buckets

Does anyone have any Idea why my Ph is raising everyday, even if im not adding anything?

Have you calibrated your pH pen? If you have, how long since the last time. Some pH pens also need to be "hydrated".

Some other questions. How long have you been using this setup, and did you rinse the coco out?

I know others will ask.

Do you have a bubbler in your water ?

A bubbler in the water will def raise the ph, make sure you check without the air stone in. I have the same problem with my nutes, I’ll mix 3 gallons, ph to 5.7 for coco and the next day it will raise to 6.2- 6.6. Im not sure why but my thinking is maybe the nutes r buffered and designed to stay in that range.
