Leftover bloom booster - use or not?

[ambersartain]

Thanks, very informative.
So, let me see if I'm understanding this, fertilize more heavily (how heavily?) when the plant is putting on leaves and roots, fertilize lightly when setting spikes (am I saying that right?) and blooming, then do I keep fertilizing lightly until vegetative growth, or drop off all together? Do I change immediately when I see buds forming or let it grow a little more? Probably won't hurt to start soon.
Also, how much fertilizer during each of these periods? If you can give me what ppm are considered heavy, moderate, and light and tell me how to figure it out from the info on the bottle that would be really neat, or I'm sure it's probably already been explained somewhere. I'm thinking I read somewhere to never go to heavy on the epicyclia or tolumnia. I can't remember for sure. Also, I'm probably going to try to feed at every watering. I do get lazy though.
Oh, and they're pretty close to a sliding glass door, it gets kind of cold right now, really warm during the day and then cold at night, prob. about 60-65F, never measured though. They seem to be handling it okay. I tend to keep them very dry, just soak them and then let them dry out. Probably should be getting a bit more water, esp. the phals.
