Phal lost some blooms, but is back now... do I prune?

[Jdcampbell]

New to Orchids, I bought four different Phals back in October. Everything was going great, until we went away on our Honeymoon in Dec. Away for a week, Im not sure if the house sitter watered or didn't, but they weren't looking too hot. Two days after returning, my house was suddenly infested with ants, and they had made their homes in my Phals. In all four plants, the blooms shriveled and fell off. I repotted, pruned the two that lost all their blooms and they seemed to thrive again. However the two I didn't prune... The both have blooms currently, and are only one spike, but they each lost 4 or 5 blooms. Is it just best that i Prune them all the way down to begin the new growth, or just let them be?
