Mark,
Obstructions may or may not have the same impact on transmitted and
received signals. Obstructions near the CPE can sometimes have a bigger
impact on your CPE transmit signals than on the incoming signal from the
AP.
Yeah, if all the signals incoming to the AP are low then you have an AP
or an AP antenna system problem.

Client is a CPQ-19, 200mw/19db
It is mounted on a 45 foot mast. If it was obstructions would I not see
it at the client end as well?
I was kinda thinking #4, I need to go through all of the clients to
compare the different signals.

Mark,
For starters, this can be due to:
1. Lower transmit power on CPE radio compared to AP radio (the CPE
transmitter may be bad or the CPE may just have a lower rated power
output than the AP transmitter)
2. Too-low CPE antenna gain (use as high a gain as the FCC and the
homeowner and the antenna mounting facilities allow)
3. Obstructions at or near the CPE end (you may need to raise the
antenna higher)
4. Low sensitivity on AP receiver (does this disparity happen on all
clients or on just one client?)

I run Mikrotik AP's, 15db 120 sectors, WLM54G radios, running Tranzeo
CPQ radios. I have noticed on one sector specifically but not positive
about the others, that the CPQ can see the AP with a -75 and the AP
will
see the client a -90. I don't understand the disparity between the
radios.
