2c/5c Plo 6 max.

-Villian in the BB with 54bb and dealt 7c6dJs5s.
-utg (29bb) and CO (100bb) and BTN (190bb) limp in. I check.
- Flop comes in [4c 5c Jh], me utg and CO check w BTN betting 3.2bb, i call w everyone else folding.
- Turn is 4h pot is 10.8 bb, we both check.
-River is 3c, i bet 3bb, BTN raises to 19.5 bb i call.

Going through my database, i have noticed a pattern of me flatting out of the blinds and carrying on with subpar straights/flushes or trips.

Thanks,
