I have a MBVS fig tree which is about 4 feet tall. I wasn't paying attention when 
I was fertiling my plants. I use Miricle Grow Liquid Fertilizer. I put about half a cup in a liter of water and put about 1/3 of it in that fig pot. Normal directions are 1 or 2 teaspoons in 2 quarts. Now that fig tree's leafs are drooping hard. Should I water it? Is it going to okay? 

When did you do thi? If recently I would flush with water

It was recently, like 2 days ago

if the plant was well watered before the fertilizer, it is probably not an issue. It the plant was dry, could be a problem. At this point, it will probably be what it will be. If it looks fine, in a week, you are probably good to go.

I would flush it out with water, too.  For potted plants it's the small scoop in a gallon.  The TBSP per gallon is for plants in the ground.

I flushed it yesterday and know it is perfectly fine, thank you for the advise. I will watch out next time
