PH swings

[burrr]

I've only got a couple of DWC grows under my belt, but I'm starting to see a trend with my ph swings. It seems like its always climbing during veg, stable during early and mid flower, and starts to dive at the end of bloom.
Is this just me?

Mine seems to go the other way. climbs in veg, and drops in flowering. Are you using tap water or something else?

I've been running tap, and recently switched to RO.

Maybe this just means that I normally under feed during veg, and over feed during flower...
