I pruned my lemon tree and used a new fertilizer Down to Earth Citrus Mix (6-3-3) in March and the few small lemons that were growing fell off, but I have a ton of leave growth. I usually have over a dozen lemons by this time. Did I use the wrong fertilizer? Did I prune at the wrong time?

Pictures are after fertilizer (now) vs in February before fertilizer and pruning. Should I try a different fertilizer now to encourage fruit growth?
Any advice is welcome as I am new to this!
