Over potted? And other rookie questions

[Plants2295]

Hi Orchid Lovers!

I am so excited to have found this board. I have some questions, as I am very new to orchids and plants in general. I am pretty sure I over potted my orchid. I think it is a mini orchid, and I have it in a 4 inch pot. I put it in a new pot 2 months ago. It doesn't have a lot of roots, and it frequently slumps over and then I shake some of the bark out, reposition it, then pour the bark back in. This is probably not ideal. Should I leave it in this pot or try to re pot it into a smaller pot? Will completely taking it out and repotting it be more stressful to the plant?

Also, and this might be a dumb question, but how exactly do I fertilize it? I have been bottom watering it, then after every other watering I take about 2 cups of water with fertilizer and basically bottom fertilize it too, if that makes sense. I leave it in the fertilizer water for 5-10 min, and pour some of it on top. Then I take it out to drain and dry out a bit before putting the plastic pot back in the decorative pot. I have no idea if this is what I should be doing.

Even with all of my bumbling around it's still not dead and is somehow is growing new roots and a new leaf. Any advice is welcome.
