Everybody has been so helpful for me I figured I would take advantage and ask one more question. This was a dormant rooted tree that I brought inside to get going early it's mixed in potting soil and has perlite on top but for some reason it gets the spots on the bottom leaves and then they curl up and fall off. It only happens at the bottom leaves and I've lost four leaves already. I have one 120 W Bluetip frosted grow plant lamp above it which is only on for nine hours to 12 hours a day is a sunburn or my overwatering it?
Ps it is in a clear storage box with a sheet of real glass as a cover.

Could be water stress.  (Either direction).  Do you know if it's got healthy roots?

Doesn't look that bad.  Ficus Carica is not an ornamental plant.  The lower leaves yellow and fall off eventually for many reasons. 

Did you spay any fertilizer on leave? I noticed something similar on one of mine after I sprayed miracle grow, not sure if that was cause.

Looks like them tiny 'hard-to-see' nasty spider mites?
They usually like dry air conditions and tend to lurk on the underside of leaves.
You may need a minimum 10x magnifying glass to actually see them.

Taverna78, please go to the control panel and put your USDA planting zone in the signature field so we know how to help you.  I'm assuming you are East or MidWest cuz you are rooting inside, correct? 

I'm thinking maybe too much water/humidity?  Figs don't like wet.

What variety are the figs?
If too humid can get mold issues on young leaves.  Maybe try lower humidity to 65-70%?
