Ferment stinks like rotten eggs

[kenfyoozed]

I started a new wash last night.
3lbs of brown sugar
7lbs of white sugar
1 can of tomato paste
added water to reach Sg of 1.077

Also added a "yeast bomb". Consisting of:
1/4 yeast
1/4tsp epsom salt
5 tsp 21-0-0
2 multivitamins.

This thing started ferminting fast. Airlock was bubbling fast in 30mins and has not stopped for 24 hours. I Pitched 1/2 cup of yeast when the temp was 84*f. I did two new things, 1) I used the bread machine bakers yeast that comes in small jars. 2) I used tap water.

After 20 hours the Sg is 1.034. The air coming from the air lock smells like rotten eggs. I searched the forums and found some information, and the thought of contamination scares me. The liquid smells fine and taste fine, but the off gassing smells horrible. What have I done wrong? Am i safe to distill?
