Question on PH in Waterfarm

[Growdude]

I have the 8 bucket with remote resevor. Currently I check my PH/PPM in the main resevor.
My question is should you check it there or in each of the buckets resevors?
I notice the PH and PPM are much higher in the buckets due to constant recirulation and evaporation.

Does anybody understand what im saying?

I do. Adjust the levels in the main resevoir and try to figure out why it's changing so much. Let me ask you a rookie question, did you calibrate your meter/meters? Did you wash your Hydroton?
I've found that evaporation doesn't have that much effect on PH.

I have calibrated my meter, also Rinsed the hydroton.
Maybe not as good as I should have?

Ill keep and Eye out for anything else.

Plants are doing good so I guess I should not worry, and Im going to change out resevor soon also.
Thanks
