Fertilizer ( the nitty gritty )

[jai_star]

Straight to the point i've been growing orchids for 3 years and has had a lot of great results and some not so good. I tend to fertilize weakly with every watering and do a flush of clean water every now and then. I do this for all my orchids is this really necessary? I know for Phalaenopsis they are heavy feeders and love to be fertilized often. How about for rhe pseudobulb types such as Cattleya and Miltonia , Oncidium and Zygos? Surely they should have stored reserve and not need as much food.

I ask this because I have a Cattleya that always put out growth and sledom flowers and when i asked an expert he said he only feed his Catts twice a year OMG i was thinking. So what's the routine that everyone on here has?
