Weird Spots On The Leaves - Please Help

I first noticed the spots on only 1 leaf about a week ago and it has since spread to a good percentage of the leaves now. I wasn't worried at first, thought it might just be dusty or something but now I am very concerned.

It is raining so as soon as it stops I'll snap and post some pics.

Does anyone know what it could be and how I can reverse or fix what is happening?

I would really appreciate some advice and help with this. I have been babying my plant and really putting in the time to research and gain knowledge on producing the best plant possible. I would be so sad if something happened now this far into the plant's life.

Thanks in advance!

Delta 9

could be PH? or Ferts.

does not sound good...better hurry with pix...lw

I confirmed they were indeed spider mites and went to my local store and picked up some solutions to kill them.

We shall see how it goes.

pyrethrum...and citrus. sprays...make sure you keep up with maintenance after treatment.

Can you elaborate on maintenance.

Thanks
