I have a few orchids namely lc's and potinaras that do very well leaf and root wise but do not bloom. In an effort to get them to bloom, I came across an article that lists orchids as having a low ph balance. I don't want to use an acid type of additive before consulting here though, in case it might do more harm than good. So are orchids acid lovers? Or should I just continue to use regular orchid fertilizer? Thank you in advance for any and all responses.
