Okay, in searching through the forum, I found some information about proper fertilizer choices, and here is what I have decided to use for my cuttings for encouraging rooting, and then with both potted figs and in ground figs:  For my cuttings, I'm using 1/2 strength DynaGro K-L-N Rooting Concentrate (1-2 tsp per gal water). As roots start to appear and I start to see leaves pushing out, I am planning on switching to DynaGro Foliage Pro 1/2 strength until I see significant leafing, then switch to full strength Foliage Pro.  Once I pot up to 1 gal pots, I'll continue with Foliage Pro, but also add Osmocote Plus (the brand new "Plus" formulation has a 15-9-12 NPK ratio plus 9 micros.  I use this combination for my container citrus with great success.  For my in-ground figs, I will switch to GroPower Citrus & Avocado Food, which works really well for my thin soils (mostly DG), by adding humic acid to my soil (40 % Humus, 8% Humic Acids, controlled release nitrogen, 4% magnesium, 4% sulfure, 2% iron, additional micros and soil penetrant.)  Hoping this will work well with my figs, as well as it has for my citrus.

i have been fertilizing 1 gal container and up. so far MG has been working for me fine. for 1 gal, i give 1/4-1/2 strength and they seems to be working ok. for anything larger, i'll give full strength. once the tree is at the height i want, i change to lower nitrogen fertilizer like the "blooming" fomular.

Hands down go buy a big bag of grass starter fertilizer. I even use it on rooted cuttings with tons of success. It does not burn roots. By nature the starter fertilizer is very gentle and releases slowly. It's fairly cheap when you consider the amount you get.

I am using fresh worm castings mixed into water and applied to the cuttings.

I buy a bag from the local garden center that is specifically labelled as a starter fertilizer for grass.  This fertilizer by formulation is gentle stuff. It's meant to be spread right along with unsprouted seed. It doesn't get gentler than that! My cuttings love it and it's slow release.

Great, thanks!!

i have used miracle grow, i wouldnt say with great results but desesent and use compost and manure. I am thinking this year i will try a more organic aproch blood meal/bone meal fish oils along with compost manure and a shot of super thrive at watering times.

For pots, I recommend Miracle-gro. It is simple to use, hard to screw-up, easily available, something that people new to plants (figs or whatever) can deal with. In-ground, I use 16-16-16, which is cheap and easy to obtain. Beyond that, there are lost of choices, strategies, etc. --- Organic, non-organic, manures, slow release, etc. In-ground I do use Citrus and Avocado fertilizer once a year, on everything. It has several minor nutrients that our soils, here, lack.

Jon, that's why I use Osmocote Plus.  It is a "no-brainer", and in my very humble opinion, a superior product to anything else I've found our there, as far as time-release products go.  The NPK ratio is very good, plus it has micronutrients, which I have not found in any other time release product.  I apply it twice a yaer.  Super easy.  And I agree, we have micronutrient issues here, we are especially deficient in Manganese, and that, combined with colder winter temps and slightly high pH, causes issues with the locking out of Manganese, and secondly, Iron.  The humic acid helps to acidify the soil a bit.  I have also on occasion put some soil sulfur in, with a few of my citrus cultivars that seem to have more issues during the winter with chlorosis, and that has helped.  Figs of course, are dormant during this period, so not quite as much an issue, but I really like Gro Power's products, they are very good quality, and are really designed for us here in S. Calif.  Great stuff :-)

Not saying its the best just what i use only.
Miracle Grow along with some lime.
Here are some examples of some of my fig trees.
