Could be either or. My guess would be its a watering problem. As yellowing leaves can be a sign of over watering. If you ask me, there must be some exact watering sience to growing tomatoes in containers. I've never had good success with tomatoes in containers. At the same time people with limited space have no choice. So you work with what you got.

its Psyllids insect or Beet leafhoppers

I bought a meter to check the moisture level today so I'll be checking the moisture every day for a while to see what's up with that. I also found some ber on some of the tomatoes on a few of my plants so being a 1st time grower I'm in shock.
Every thing was going great and all of a sudden I get hit with 2 problems.

Since you're in California, my first guess is nematodes, my second verticillium wilt. Here are photos of these and more from UC:

Here is a better photo of nematode damage, which was my first guess due to my long, sad experience, and looks very similar to yours, too:

Yellowing leaves and BER are both signs of over-watering. It's particularly difficult to keep the watering even in containers. I would think that nematode damage is limited in containers with good potting mix.

Verticillium would be *very* unlikely in a pot unless garden soil was used, or added to the potting mix.

The same goes for nematode problems.

And I question how one makes the diagnosis of "Psyllids insect or Beet leafhoppers."

More likely the problem is due to uneven watering as is evidenced by the blossom end rot in some of the tomatoes.
