Q. Jerusalem artichokes leaves brown

Jerusalem artichokes leaves brown with white patches and no flowers yet. I have 12 Jerusalem artichokes that are now about 4 feet tall. One has slowly had its leaves turn sickly dark brown, and one has white on the back. Now the plant next to it has a leaf turning the same. Could it be due to overwatering, or some pest or disease? This is my first year to plant them. They are in a new bed with mostly amendment, hardly any regular soil. I live in zone 8 in Safford, AZ. I have been watering them every day.

You are looking for evenly moist soil. You need to check the soil before watering to see if it needs to be watered.
Inspect the leaves for any signs of insects. Neem Oil is a good treatment if you find anything.
Here are a couple of links.

Q. Jerusalem artichokes

I have some really big bulbs. I think they need to be cut , there were 5 to a pound. After cutting, do I need to let the cut sides heal over, or can they just go in the ground. How long to heal?x

I don't think I would recommend cutting them this season. You will need to ensure that each segment and a shoot eye, and root nodules. This can be done after the season is over. This way you can see root sites and shoot sites very clearly. I would wait to plant them after they have healed some as well. This can take a few days or a week or so even. This will help prevent any rot from happening. This article will give you more information on growing these: https://www.gardeningknowhow.com/edible/vegetables/jerusalem-artichokes/growing-jerusalem-artichokes.htm
