Scale help please!

[Phal grower]

Think I have me a scale problem. From what I've read on the net anyway. First I notice brown bumps and just wiped them off (three little bumps). Now I've noticed white oval spots with brown bumps alongside them. From what I've read the white ones are females laying eggs??? And the brown bumps are the mature adults that don't move??? Anyway, it can't be good ha ha. So far, aside from the first (three little bumps), they seem to like only one of my plants(I have three of the same in seperate pots). I hate to isolate them(I only have a small light garden) but I know I should. I have high humidity, good air movement, don't know if that helps. Any ideas?
