brownish tint

Hi everyone,
I need some help/suggestions and advice.
Here is my issue: I have a Bald Cypress that is 2 years old, it is roughly 12 feet tall.
This past weekend I noticed that it seems to have brownish tint to leaves. I examined it for insect none to be seen.
I water tree 2 times a week three gallons of water using a five gallon home depot bucket, the reason I use three gallons is that the diameter of trunk is about  three inches maybe a scoia bit more.
Also I live in central Alabama it not dry here yet but it's getting kinda hot. The soil is a sandy loam.

Tree leafed out very good last year and a pretty green until fall.
This year it's full of leaves but this brownish tint to tree has me at a lost.

Does ay one have an idea of what's going on with it and what do I need to do?
I am attaching a couple of pictures that I hope shows the tint, but these were taken with my Iphone so they may not be to good.
All replies and suggestion are more than appreciated.
