Cherry Tomato leaf tips turning a dark then yellow color

I am growing cherry tomato in a grow bag and some of the leaf tips are turning into a really dark color and then to a yellow. This is how 3 different leaves look. https://imgur.com/a/oZwUj

Any advice of what could be the problem? Thanks.

The first thing, remove the infected leaves and trash them, next I would try is mixing a 325 mg. aspirin into a gallon of water. Spray the entire plant soaking it.This will cause the plants natural defense system to active.this will slow the progress or stop it. I had the same problem last year, some plants recovered and I also lost some. You will see a difference. It could be a nutrient problem virus or a fungus problem.Hope this helps, Consult youtube for many videos explaining what you are dealing with.

Your leaves are a little purple. That is either a response to cold or not enough phosphorus. If this plant is in a small container it might be time to fertilize and move up.

The spots looks like fungal. It may be early blight. Definitely remove the leaves. Sick plants need to be either discarded or isolated from healthy plants to prevent spread of disease. Soil should not be reused unless you sterilize. Ditto with the pots. Soak them in physan or 10% bleach solution. I just put the pots in a bucket for a week and then rinse. Stressed and starving plants will be more susceptible.
