Advice on Fertilizing?

[richardb]

Like Ray I fertilize at every watering. I use a combination of Peters commercial (not orchid) fertilizers according to season and adopt the regime of "weakly weekly" which gives excellent results.
I understand the need to dilute ordinary garden fertilizers to maybe 1/2 or 1/4 strength but have never understood why people do that with specific orchid fertilizers. Much research has gone into those special potions so surely the instructions on the bottle should be followed.
