Advice on Fertilizing?

[orchidlauren]

Hi, beginner here! Lots of questions on this, but I've gotten a few new orchids and just want to know if I'm doing things right. At the moment i got 5 pals and 1 new Miltonia 'Sunset'.
At the moment I use Miracle Gro Water-Soluble Orchid Food on my pals along with Miracle Gro Coarseblend Orchid Potting Mix. Food Ratio: 1/4tsp: 1 gal.
1. The food suggests using it every 2 weeks but in my opinion that seems persistent in fertilizing, especially as it gets colder. Do I continue using it at this rate or start using it once or twice a month depending on current temps?
2.Do I continue using this fertilizer while my orchids are in bloom? Some say not to & some say to continue.
3.(if i stop, do i begin again after the flowers fall off?)
Can I use the same Orchid food I use on my phals on my Miltonia?
4.+Completely my fault but I had left 3 of my phal orchids in the sun for a too long resulting for them to, unfortunately, suddenly drop their flowers. Do I continue to use the food/fertilizer on them like normal to continue growth/rehabilitation?

Sorry for all the questions! I have many more of them to come, I just want to keep all of my plants happy & healthy
