Are there models trained on both x-ray and ct scans for COVID-19 prediction?

I've only come across models that were trained and evaluated on one of these data. I don't see why it would be a problem to do both, as there are many similar features.

Hi Alex,knowing you I suppose that all nutrients are OK (Mn and Fe?)

Are all plants of this genotype looking the same? Can you show some pictures of healthy plants that are grown next to it. It does look a little bit like some of my tomatoes that got uneven light, especially suddenly more light than they are adapted to. I noticed some genotypes react a bit differently.

Parm Randhawa

Since you said some plants are showing symptoms, this rules out genetic. In case of Genetics, all plants should be that way. Looks nutritional deficiency. STEM (soluble trace elements mix) spray at 8 oz/100 gallon works well for my plants (but my plants are not tomato) .
