Grow Mediums Ph in autopot base

[Bodacious Budmonster]

is it good practice to be checking the PH level in the base that the pots sit in.
I just take the readings from the res however I have read that some people test the ph of the base if they have issues and sometimes the PH is higher.

Would you expect the Ph to be the same in base as the res and if there is a difference is that an indication to something and if so what.

I am debating getting a portable PH pen but don’t want to bother if there isn’t any point.

Thanks

Not really sure as I've never checked PH going in the res or trays. I've gone from using RO water to well water and from AN nutes to Megacrop.

How did the AN work for you? What is the differences you see in Megacrop? TIA ✌
