It sounds like you just kept the first batch too wet. Also; You handled those sprouts 3xs. Not a good idea. Best to place them in a starter cube, peat pot, etc, either right from tyhe start, or omitting the paper towel. I always use 1.5" rockwol cubes and get as close to 100% as I would dare claim in propagation success. I will show you a pik. I use these starter cubes for seeds and clones and they provide an awesome foundation for a strong plant.
Following a simple regimen produces the most excellent hassle and hands free propagation method. Hope you do not mind me posting some piks.
Notice the bump. That is a small tuft from the corner of the cube I gently place over seed hole in order to force the roots to take hold.
A couple seeds popped through
2-3 days: Almost all are thriving.
100% healthy
Week to 10 days
Another one - week to 10 days
It is important to invest in a T5 2’ 4 bulb lamp like this for propagation and early veg. Notice the lamp only 2" from top of seedlings. A 4" fan should also be blowing across this space in order to strengthen the stems. Temps 75-85f

About ready to transplant to 1 gallon nursery pots. (easier to extract for re-potting than small cloth pots that tend to bulge)
Time to remove outer paper and transplant.
Consider this my good deed of the day and good luck. Let me know if you need any help.
In regard to the seeds. Some of our genetics are small (micro seeds) but, seem to propgate very well. Even lighter seeds always pop for me. I also believe that different strains have different color and depth in the shell, so I do not worry about how dark a seed is unless it fails over and over.
