Phal help, please! I'm so confused!

[Yanquister]

Thanks so much King, I really appreciate your help. May I pick your brain just one more time?

A couple of people have sent me messages saying my potting mix is just the worst thing EVER and that I should repot right away, which was a shock to me because other than my issue with this one leaf, my orchids have thrived, flowered and grown significantly over the past several months. To the point where two actually look ten times better than when I bought them from the orchid nursery. The media I use is made up of peat moss chunks, orchid bark, hardwood charcoal and lava rock.

I'm not an orchid expert (obviously, considering I'm asking you so many questions), but from what I can see, this media is giving the orchids the perfect combination of moisture and aeration for the roots.....what is your opinion on my media?

Thanks so much! Again, your advice is great and I appreciate you taking your time to help me!
