About half the leaves so far have different shaped brown spots. Is this still Sun burn damage when I first planted it more than a month ago.

It is sunburn, but there is some other issue causing the production of weak, chlorotic tissue. Mine did that (and still do some times) because of boron deficiency. Calcium deficiency causes virtually identical symptoms -- chloritic, weak, floppy tissue, and yellow lines parallel to the midrib. I get these symptoms most strongly after I really push the plants with fertilizer and water -- the growth outpaces the movement of micronutrients that are taken up slowly into them.

Don't do what I did at first, which was to throw all kinds of things onto the soil to try to fix it. If you don't identify the actual cause of the problem, you will probably just exacerbate it. A safer approach is to lay off the fertilizer for a while, and try a foliar spray of a complete micronutrient product. And I can't emphasize enough how useful I found a professional test of my soil.

My duties has not allowed time for a soil sample but I will get that done as soon as practical as you suggested. I may have pushed the fertilizer a bit too hard in the beginning as you noted. I will make sure I hold back and keep it on a better schedule.

I really appreciate the advice.
