Before you start your feeding, I'd do a flush and test the pH of the runoff. You had bone meal in there as I recall, which is in fact a good organic fert, but isn't what you'd consider a 'standalone' fert since it only contains CaPO4. You still need a source of N, K, and other micros. But adding too much before you have a good handle on soil chem is potentially dangerous. So get that pH # and we'll get you going. In the meantime you can always give a weak foliar feed of that fert you just got; mix less than 1/2 strength.
The plant looks quite low in the pot- circulation will be hampered by the rim. Try citting the rim of the pot down to less than 1" from the soil surface to prevent stagnant air sitting arounf the palnt.
