Is one of my nutes causing my PH to rise in my res? (Canna, Roots Excel, Great White)

Hey there,

I run a RTW coco coir setup, and have a res where i keep water for my irrigation setup.

Room temp is 62-68, nutes used:

Canna Coco A/B
CalMG
H&G Roots Excelerator
Great White Beneficial Bacteria

I mix everything together in 4-5 gallon batches in RO water, and then ph to 5.8. There is no air stone, or recirc pump in the res, i just mix it up manually couple times a day.

By the next day,ph will be at 6.3 or so! I even came home today, checked PH and adjusted it to 5.8-5.9 and 3-4 hrs later it was up to 6.2.

My speculationis that the Great White is messing with the PH, any help?
