Hey AZ, I germinate seeds the same way you did and rarely have any problems.
I would mist every day to keep the soil moist until they come up. Your not going to over water with a mister in a large pot.
The directions for Coco Loco say to completely wet the soil just before planting and then as needed. The organic soils you used require moisture to get their microbial life active. If you didn't wet the soil first I would start using a slow watering around the outside edges of the pot to get all the soil moist down to the bottom, but not all at once, maybe over a couple days. Just a little at a time and not in the center where the seeds are. Just keep misting the seeds daily until they come up.
Coco Loco recommends their liquid nutrient system. Both California Hot Soil and Natures Living soil are fully organic products which don't need liquid nutes, so from what you described mixing them I'd watch and see what happens. Looking ahead in a couple months, if things are going well, you may want an organic amendment mulch to lay on top of the soil as they transition to flower. Natures Living has info on that. Best of luck!
