Hey fellow figgy friends!  I have read some folks like to give their pearlite rooted cuttings a little watered down miracle grow.  I have a bunch of decently rooted plants in coco/pearlite mix.  I have an indoor grow room to keep them going over the winter.  I would like to keep these little plants healthy and lively until the weather warms up; however, I do not want them to grow very large.  Don't get me wrong, I want healthy plants, I just don't want to run out of room. Probably something to keep the leaves a nice green and help them grow a little.   In the past I have had a couple plants grow like weeds indoors and right I have limited space.  I understand that some vigorous growth might be unavoidable, and that is fine.  My top priority is keeping my plants healthy.   What do some of you more experienced guys and gals recommend adding to the water?  Thanks in advance.

Epsom salt and fish emulation. Use very little fish emulation. Keep in mind its rotten fish. Its very good for figs. Epson salt helps deliver the nutrients matter in what you decide to go with. This salt helps to make nutrition easier for the plants to absorb.

I wouldn't use fish emulsion inside. Fish emulsion has a lovely odor that is best appreciated outside.  For inside, I like Dyna-Gro Foliage Pro. Don't use much of it though. 

LOL !!!!! I did say just use a little bit.

1/4t of Foliage Pro / Gallon is their recommendation for a "Maintenance" dose. You could use that every time you water.
