How do you expedite or manually send resources to a colony? I have surpassed 30 cycles and it has sent all alloy and some food, but no colonists.

I removed resources to be picked up for the assigned loader ship but it stays docked at the Tiqqun.

1. You have to train colonists by building a "Colonist training center", and inside it's panel you must click:
"Train 15 colonists" (or "Auto-build" ON)
It will use non-workers for the process. (You have to have some in your sector!)

2. Than you have to transfer those trained colonist to that sector, where the docking bay is for your cargo ship, which you have chosen for the material transfer.

3. You have to have enough space in your docking bay to fill with those colonists, equal to you cargo ship's capacity.
