Can I pick your brain?

Hi Vegetable Lovers,

The majority of my transplants are all in the ground at this point. Most have established themselves. I did harden off my transplants but give myself a grade of a "C" for the hardening off-process.

Best batch of snap peas yet! Building taller trellises next year.

My black beauty zucchini leaves look a bit concerning. ph? Iron deficiency? Too much N2?The MM is made well. Here are the leaves:

The cucumber leaves seem to have a hint of yellow too. I've given 2 servings of compost tea over the last month and a half. Any suggestions would be appreciated!

Thanks!

Could it be powdery mildew?

can you wipe the concerning part off the plant or is inside the leaf its self

Just a guess...it seems to me like you can see through the leaves - my initial thought is early-stage chlorosis. Note the veins are all still a nice green color.
Apparently may be caused by iron deficiency or pH too high.

Maybe downy mildew?

What ever it is I would take it off. The new foliage looks great.

Could it be that it's been chilly? Especially at night. Peas like it cool but zucchini likes it hot. Beans and cuke too. It may be a start of a problem tho. I'd cut off the offending leaves, be careful to not get the leaves wet.. The compost tea should help. Monitor the temps and just be patient. Hot weather will come and you will have many zucs.

Thanks for the advice and experience. I am going to clip the lower leaves. I think part of the problem is the root cluster may be a little compacted. The rot system was MASSIVE when I transplanted. THe warm months ahead will help some too.
