Is This Spider Mite?

[PGB1]

Hi All,
I have some small Gem Box Inkberry shrubs that are currently indoors until I can plant them outside when the ground thaws. After 3 months indoors in the garden window, two of the plants have some sticky, foamy looking white stuff growing on the branches. The other 3 plants have none. I washed the white off with a gentle spray of water.

I searched here and am guessing that the white stuff is from spider mites.
Do you all mind to check the photos below and let me know what you think the stuff is? ( I apologize that the photos are fuzzy. I'm not the king of camera stuff.)

Thanks For Helping!
Paul

I can't see anything but I expect that the plant is not liking the growing environment its in. Your plant is getting sick. When its some what dry take the plant to the sink or shower or outdoors and cover the soil with plastic. Very gently tilt to one side and spray the plant down washing top and bottom of the leaves gently. You can mix a little cold pressed neem oil with one drop of dishsoap to warm water and spray the plant after the bath. Then spray the plant every three days for a total of 12 in all. Thats for indoor spider mites. Good luck friend.

I apologize that the photos were poor. The white stuff is the mystery growth. (Arrow on the photo below)
