Yes, I would recommend liming your container mix. I use ProMix for my containers, and for every 5 gal of mix, I add about a cup of granulated/slow release fert (whatever is on sale), and a cup of dolomitic lime.
I don't add anything else until after the first fruit set, after that, it's a handful of the dol lime and a handful of the slow release every couple of weeks. And I also occasionally foliar feed with seaweed emulsion for trace nutrients.
Also, be sure to mulch well, leaving some space around the stem.
