My Calibroachua was full of beautiful blooms and full foilage. Now 2 weeks later leaves began to turn brown and looks to be dying.
This will be caused, commonly, but high pH over overly moist soils that do not get a chance to dry out between waterings.

Thanks for the info!
They are tiny, about 1/16” long and thin
Those appear to be whiteflies, a common pest. Here is info on how to treat for them. The first link is for outdoor plants and the second for indoor. https://www.gardeningknowhow.com/plant-problems/pests/insects/whitefly-control.htm

The plant has stopped blooming after three weeks. Will cutting it back encourage more blooms, or is it done for the season?
This could be an indication that something is off in the soil.
They will, usually, bloom all season until winter. They are also self cleaning, which will mean that they do not require any pruning.
I would test the soil for nutrient deficiencies, or pH imbalances. These articles will help:

This intense heat has wilted my calibrachoas. any way to get them flowering again. I have put miracle gro on them a few weeks ago. I have never seen my flowers do this before. I have always had good luck growing calibrachoas.
Million bells are supposed to flower all summer given full sun, water and fertilizer.
Are you keeping them watered in the intense heat? Though they like full sun and warm weather, extreme heat can reduce flowering. Soil should be moist but not wet. Too wet and root rot sets in.
They are heavy feeders and need a complete fertilizer. Though some say too much nitrogen inhibits flowering, calibrachoas need a lot of nitrogen so don't skimp on that in the fertilizer.

I am a beginning gardener and would love to collect seeds from plants I grew this summer to grow again next year.
Once the flowers get pollinated they will begin to die off. If they get left, instead of deadheaded, then the seed pod will begin to swell where the flower used to be. Once they swell, and start to turn dark, the pods can be harvested before they burst.
It is worth noting that the seeds will not resemble their parents. Also, many will not germinate at all. Still, what does grow may be something unique and interesting.

I bought these plants this year from a garden centre and wondered if you could purchase the seeds
The Kabloom series seeds are the only calibachoa seeds available thus far. You can find them online at reputable seed catalog websites. We don't make product or vendor recommendations but just stick with a seed-selling company and not auction houses. You could try overwintering them if they are still healthy.

I had two plants of Good Night Kiss. One was normal sized blossoms approximately 2” diameter. The other plant to blossoms were half the size. Ever blossom on the plant is miniature and continues to be so. Both fertilized the same, watered the same, same soil.
Unfortunately, your photos did not come through.
Depending on the type of fertilizer, it could contain too much nitrogen and not enough phosphorus and potassium.
