White Mildew? Yellowing leaves on New Growth, Help!

Thanks for the pet info. I ended up using Mita X since I already had it. Active ingredients are cottonseed, clove, and garlic oils, smelled nice Also found out that my big palm which the orchid was near was also really buggy! So I washed and sprayed them all, we'll see what happens. If they return I'll have to go with something stronger.
