Your black mission fig looks good, and even main fig look quite big now, When will breba fig ripen? it seems that black mission grow well in cooler climate here.
Also, did you fertilizer your tree?, it might make sweeter fig, So far, I mix tomatoes fertilizer with manure tea/ lime with water, and fig tree love it and grow faster and all yellow leaves/slow grow problems are gone, Even young desert king, It bears some main figs.
I got black mission few months ago, I plant them in ground but it doesn't grow very much and dropped its breba, last week, I checked its roots and I find that I added too much sheep manures at root area, It dried up as hard shell, I fixed this problem and gave it couple heavy dose of fertilizers hoping that it will bear some main fig.
