That looks to me a lot like Environmental Leaf Scorch, caused by the leaves loosing moisture faqster than the roots can supply it.

the tomatoes crack me up ...

and if that is cuke.. thats what cukes look like in summer ...

i gave up growing them due to disease and sudden death issues ... if thats them leaning on the diagonal supports.. you might be overplanted ...

there used to be a very active pepper forum ... you might get advice there ..

otherwise.. that last pic.. sure gives us an overview of what appears to be a healthy thriving garden ... i wouldnt go all Disney on it.. thinking everything will look and be perfect ... nature kinda doesnt work that way ...

all you do.. is total up the bounty at the end of the season and see if it was worth the investment .... and i dont mean just the money spent... also the exercise.. the meditation .. etc ... dont forget.. gardening is just an excuse for adults to play in the dirt ...

i am sure there is a veg forum ... maybe called cornucopia or some such

Thanks so much for the feedback! Yes they are cukes- three plants on the diagonal support. Might snip one of the main stems..
