Help Identifying Disease or Issue with Potted Washingtonia Robusta

Hi all,
 
Summary: After the winter, I noticed what looks like a disease on the fronds of my potted Washingtonia Robusta. Could anyone confirm whether this is a disease or just damage from bugs, and suggest possible remediations to keep this plant healthy?

Background: I purchased this Washingtonia Robusta about a year ago, and it was very healthy in its first year.  I live in Austin, Texas (Zone 9a), and keep this plant on my concrete patio, which can very hot in the summer months 100-125 F.  After the winter when the fronts started growing again, I've noticed what looks like a disease or damage to the fronds stunting their size and growth. I have noticed spiders lurking around the plant's core, and I wonder if that or any other type of bug could be the cause. 

Any theories, insight, or suggestions would be greatly appreciated! :)

    I think it looks fine, looks like a bug has been chewing on the leaves here and there, but the new growth looks good to me. I think just keep taking care of it, and eventually it will grow out of these old leaves.

    As ZPalms already said, it looks good.

    it also simply needs time and warmth to get going and grow.

    have you already fertilized them a little ?
