Tequila wash not tasting like tequila

[blackbrj]

Not many tequila posts so hopefully someone will have answers.
I've tried two times now to create a tequila wort and both times NO FLAVOR! Smells and tastes like pure ethanol. Can someone please review my wort and see what I'm doing wrong. Or just help me with tips to get more flavor. I'm a newby at this stuff but excited about the process. Thanks for any
feedback.

3.5 gallons of distilled water
10.4 pounds of white sugar
25 oz of agave nectar
1/2 cup of fleishmanns bread making yeast
38 grams of miracle grow for nutrients
3 B1 pills
4 teaspoons of lemon juice

I don't think I need to add extra agave nectar but I'm open to anything. My last batch just finished fermenting (fermenting took about 4 days) and it is settling right now before I distill. I don't have a final SG yet.

Thanks to anyone.
