Sweet Peppers Wilting, Help!

[Bluemarkt]

This is my second attempt to post this, did not see the Verification issue below.

This is my first season for EarthBoxes (EBs) with the Automatic Watering System (AWS).  I live in the North Denver, CO area. It has been a hot and dry summer.  I have installed 12 EBs with respective AWS systems on a gravel pad.  The water is hooked and running about 18 hours a day.  I have planted multiple tomato plants, multiple summer squash plants, multiple pepper (both sweet and hot pepper) plants, some basil and some beets.  The beets will be swapped out for Coe plants in about 4-6 weeks. 

The problem I have is with the sweet pepper plants.  I have attached a photo of the wilting that is going on (photo not attached, it keeps crashing every time I try it with photo).They look like they are going to die.  Are they getting too much water?  I used the EB growing media along with the fertilizer and dolomite.  The media is damp, the AWS is delivering water.  Not sure what to do.  The hot peppers and all the other plants are doing fine.  Help!

Can anybody tell me how to add a jpg?  Every time I try to attach it comes ups with an error 509.

First year EB'er here too, so take this with a grain of organic fertilizer .. my sweet peppers started doing better when I started top watering them a bit in the afternoon/early evening, along with filling the reservoir.

Same question here.  I can't add a photo - keep getting an error message!

That's an image I Googled. I think this forum software works with links to images that are externally hosted rather than uploaded here.

This is from pasting that link into the img brackets
