Thank you guys for your advice!
Thanks Rinzo, I will by see weed extract.
Thanks Rosie, I will repot it.
Here is my little girl not looking so good today...:-( Wilted leaves and flowers...:-(
I repotted my phal a week ago in Miracle Gro orchid bark, but I had purchased and waiting for arrival of Fir Bark Classic Orchid Mix from rePotme.com. So I will repot it again.
Any other suggestions?
