Two more Grape Slurri girls dead. Disappointed

No taproot action after planting into soil... I have 1 more Grape Slurri seed. I changed everything in my soil that I should have, plenty of aeration, less water, removed chlorine, all organic nutes, added mycorrhizae.. and nothing
I contacted Roc a few days ago and decided to tell him not to send me anything in replacement, but I am going to send him an email and tell him that these didn't come up.
Also, I gently dug up the auto seed to look at it, only a minimal amount of growth in these 2 days
