Hi,

I'm growing several varieties of chili plant indoors and I've noticed lately there are some nasty looking white spot appearing on the underside of the leaves this is on about 10 of my plants now and I'd like to know what it is and how to get rid of it.

This is the first time I've grown anything so any help would be very appreciated

I've included a link to a hi res image and would be extremely great full if someone could give me some information
