I am going to add to your excellent post because I do not know either.
My addition to the post --

If the leaves are brown at the edges, how do I know if it is a
fungus starting on the leaves or just over watering?


Mostly edge browning indicates something like too many mineral
salts in the soil. Usual cure is leaching, especially with potted plants.


Can over watering cause the entire leaf to turn brown?

Yup. Sog out the roots and the plant dies.


I have also trimmed off the brown leaves also, still the some of my
plants have continued to turn brown and die. I have also used those
stick in the ground water dryness testers to know avail.

How hard is your water, and what are you using for fertilizer?

From some garden books I have read, it is a good thing to place
marigolds around the edge of ones garden. Applying too much water my
marigolds look awful and my tomatoes look great. Less water marigolds
look good and tomatoes seem to suffer - I cannot seem to win

My sincere apology to the original poster if I wrecked your thread.
Please answer the original posters questions first.

Thank you Kay for responding

I think you may have hit at least my problem. During our early drought,
I have used my "Hard Line" an awful lot from my well. The TDS level on
my hard line is 2300. As for fertilizer - only compost / cow manure.
If I use the soft line, salt usage will go up some and also I thought
the soft line would be worse for the plants.

I am wondering now if I should have used my soft line instead?

In the past, my rain barrels has always provided plenty of good water
for my garden during the dry times. In the thumb area of Michigan I have
had only four good rainfalls this entire summer including yesterday. It
would be cheaper to buy my veggies than use the RO water. My pond is too
small and would drain fast as it is also very low. I can add a low cost
sediment filter to the hard line if this drought continues years to come
or use the soft line. So far my well has done well has never gone dry -
yet.

I am also not alone, almost everyones gardens and farm crops are not
doing very well around here.

Enjoy Life ..... Dan
