Nov 16 - After 7 days without sprouting I went digging for the PC and AP seeds. The PC seed had a .5cm taproot so i dipped it in mycorrhizae and replanted it. The AP seed appeared rotted and was being eaten by microbes. Soaked a new AP seed for 24hrs and planted it.
Nov 20 - Repotted BD and BB from solo cups to 7Gal smart pots
Nov 20 - PC sprouted
Just a thought, but you might be overthinking this entire process. The white "mold" on your soil surface is likely a friendly soil fungus, and could be working with your compost teas and microbes in the soil breaking down all those nutrients into plant available forms. Happy Growing.
