Budbro that is exactly what some of mine looked like that I lost this week. They were about 10 days in. A few had sprouted roots and were fine but 4 of them started wilting and getting "sunken" areas on the leaves. I pulled them out and they had the same grayish, soggy look. The one condition I did not control well was temp. When I read ranger's comment the light-bulb went off. I was giving them cold water and the room temp was 50-70F, usually on the cooler end. I took some new ones tonight and I'm going to put a heat mat under them with some thing to use as a spacer, so they're not sitting directly on it. Hopefully it will be enough to warm up the interior of the dome.
