Hey everyone, back again with yet another newbie question

. I recently purchased an Onc. Sharry Baby "Sweet Fragrance" in spike about a month ago. I switched it to S/H immediately (otherwise I'd be afraid I'd kill it quickly!) Well, the time has come that it should be blooming in a few days... I just watered my 'chids and while doing so, a question arose in my head. This will be my first orchid that will be in bloom that I have been fertilizing. All of my previous orchids, I realized that I needed to fertilize them after the flowers eventually fell off. I currently fertilize with Dyna-Gro KLN and Dyna-Gro Grow. I put about 3 to 4 drops of each in 1 gallon of water and water when needed (thanks to S/H) which is typically once to twice weekly. I do an occasional flushing with water only as well. When it actually produces flowers, should I cut back on the fertilizer, add more, stop completely or continue what I'm doing? Thanks!
