I don't recommend using Physan 20 without any kind of evidence that there's disease involved with your flowers dropping.
Phyton 27 is the better product and is safer to use than Physan 20. Physan 20 tends to ruin the roots of an orchid if applied onto the roots. Phyton 27 won't do that. I tried using Physan 20 and often ended up killing plants because I sprayed Physan 20 on the plant's roots. I've sprayed Phyton 27 on the roots of some of my diseased plants with no ill effect.
There's an article about using Phyton 27 versus Physan 20, (google it). According to the article, many people use Physan 20 as a precautionary measure to sanitize mounts, pots, and growing tools and work benches. Phyton 27 is the one most widely used against disease.
Anyways...
Your flowers may have just wilted because they were done blooming.
When you cut off the spike, it didn't harm the orchid any.
Phalaenopsis or moth orchids are slow growing. They will only put out on average 2 leaves a year. Occassionally they'll put on a stellar performance and grow 3 or 4 leaves, but that's rare.
It's also pretty common for a newly acquired and un-established Phal to just sit there and do nothing for months!
However, spring and summer are when the heaviest growth occurs for a Phal. Growing starts slowing down in the fall and may even stop completely in the winter.
Phalaenopsis usually naturally bloom in the spring.
In the future I would only remove the flower spike after it has gone completely dry. Leaving the flower spike on will allow the plant to possibly put out kheikis (baby orchid shoots) or even re-bloom.
