I "try" to fertilize weakly weekly. Doesn't happen often more than two consecutive weeks. Summer I don't fertilize at all, other than using the water from my koi and water plants pond. And have in some years maybe only fertilized a few times. Life gets in the way at times.
There are many ways to do this dance with orchids. Unless you get into some of the hard/tricky ones to satisfy, you'll likely not see much problem in that area.
And you have cymbidiums and didn't remember. For shame, for shame on you. Another of my favorite orchids. But I sure don't grow them for the foliage!
