Don't, it takes a while to get the hang of it and FWIW you really have to be able to see the whole plant so just from your initial pic, I couldn't tell for sure. You'll figure a lot of it by knowing which nutrients are mobile and which ones aren't - go from there to begin with.

Cheers

Calcium deficiency shows up as blossom end rot, where the outer end of the tomato has a dead area.

When posting pics of a suspected nutrient deficiency it's best to post a couple of close up pics of the affected leaves, but also a pic of the entire plant, so we can see where on the plant the deficiency is occurring. As Scotty alluded to, deficiencies of mobile and immobile nutrients will show up on different parts of the plant, so knowing where on the plant the symptoms are will help with diagnosing the problem.

Whereabouts on your plants are the affected leaves?

It's looking more like potassium to me now. Image
Here is the plant. I keep them well trimmed. Image
Closer to the plant showing mid growth leaves.Image
Closer up.

No apparent issues on fruit.
