I use 28 gauge for micro coils and even with 9/10 wraps I can barely get past 1 ohm. What am I doing wrong?

Gauge of the wire, diameter of the finished coil, and number of wraps all affect the ohms (resistance) of the finished coil. Same diameter and same number of wraps with a higher gauge wire will give you more ohms resistance. 32 gauge is more than twice the resistance per inch of 28 gauge:
