Last year I tried working with a seed starting mix and had results that matched those from the last several times I get convinced by other folks to try it again... sketchy at best. Back to tried and true plain old potting soilless mix. I think the seed starting mixes are too compact and don't allow air gaps (oxygen) to be at the seeds. Potting mixes may have chunks of stuff in it but has worked for me for more than twenty five years and seed starter has failed five of the five times it has been tried.
