Encyclia sick?

[cory1977]

Hope someone can help me!!

I have this plant for 5 months. When I bought it, it already had brown tips shown on the old leaves. Now, it's growing three new pseudo bulbs. One is growing at the edge of the pot( all three have new spike coming out). Should I repot and separate it into two pots?

I also noticed that the new leaves has some dark spot at the tips and edges of it. And some new leaves look pleated with unevenly green/whitish color. Today, I found out the root of one new pseudo bulb is turning yellow I don't know what's going wrong...

P.S.
It's really hot recently, so I misted my plants a lot often.
I used 29/10/10 to feed my encyclia last time. Before that, I only used rain water.

Thanks!
