After talking with
@mcbuck58 on the phone and sending him more pics, decided to pull all the chestnuts out of the soil to check them for mold. Glad I did. 2 of them were obviously bad and got thrown out in the yard. The others appeared to be fine. Washed them off under the faucet and stuck this tray back into the fridge. Will be cleaning my container tomorrow and getting the Baccto soil if I can find it. Co-op says they carry it - will call in the morning.
He and I agreed this was very informational stuff for others to see and to check their own if they are growing them. This shows what to look for. Hope it helps someone in my situation. I got lucky
