I totally agree with Figpig about the water issue. I wish someone would have had told me this on my first time rooting. No doubt my #1 problem when I started rooting was having too much water on my figs. they will do Okay with Little water, but too much water will totally damage, and rot anything you have growing.
and yes, no fertilizer here on my end (some suspect it hurts young and tender roots insted of helping). also, as mentioned: don't pull them out anymore. Be patient, the roots will show, and this will be rewarding and exiting... Good luck, and remember to be aware for stagnated water... these cuttings are very susceptible to die with from too much water.
Good luck, and welcome to the forum!
