Look on the underside of the leaves and I'm willing to bet you'll find some tiny little spider/crab-looking mites. Safer makes a spray calles "End All". It worked perfectly for me.
On the second pic it looks like it may be early signs of a mg deficiency. Our local water supply here is lacking so I always have to add it myself. I ues CaMg+ from General Organics. The leaves edges curling tell me it's a little hot in there too.
