Normally, when the reel valves fail, you get high side low and low side high. It is because the valves are not holding pressure.

If the expansion valve is clogged, you get low side low, sometimes below zero. Because the compressor is sucking the freon and the valve is not releasing enough freon to fill in the suction.

Based on your gauge readings but without physically putting my hands on the system to feel the temperature, here is what I think (in order of likelihood):
1. freon slightly low,
2. not enough air to cool the condenser, or
3. an open expansion valve.
