Hello, I'm located in NJ and have Tomatoes & Cucumbers growing inside my greenhouse with drip irrigation . We have had Nights in the 40's for a few days . The Weather is inconsistent . Are my tomatoes & Cucumber plants showing signs of cold weather stress or is it something else ? Some are doing good and some not so well . What could it be ? Fungus ? Insect problem? Or just cold problem ? Thank you in advance .

Johnny

I suspect they are suffering from cold. The tomatoes may get over it but I'm not sure the cucumbers will. Don't plant tomatoes out until the temperatures stay above 50. Don't plant cucumbers until the temperatures stay above 70.

Last picture looks like damping off.
Dont get overzealous with water. You might be drounding them. Let soil dry some. If soil crusts over on top you may just need to mist top if lower soil is still moist. It would be helpfull to know how warm greenhouse gets during day. Let us know ? Warm weather veges dont grow well with 40s a nite, but, they will grow if it warms up during day.
I know ! I do it ! Tomatoes, probably struggling from cool nites, but, damage also could be fungus gnats. Check for them using a pencil and brush top of soil, hear and there. If you see any little gnats ! There probably fungus gnats. Maggots eat roots, read up on them and see. Some people swear they dont.
NOW !!! Go check ! And plant some more cucks. The ones you got are goners ! They will take to long to recover. You'll be ahead of yourself !
I swear ! 😎😎😎

Those little cucumber plants are being eaten by some sort of insect. I suspect slugs!!

Thank you all for your help truly appreciated.

.The weather have been 40s nights and 60s days. NJ zone 6A last frost date is may 18th.

The weather has been very damp and raining ALL week.

Currently, my watering schedule is 3 X a day for 20 minutes . I may reduce this to 2 X a day and see what happens .

I made a neem oil and water mix and spayed all over plants and soil . I saw little red things jumping all over , is that fungus gnats . ?

Thank you,
Johnny

Yes, the cold weather slows the plants growth down, so you need to water less and fertilize less when it's cold as well. As Daisy said, I think your cucumbers are toast, so go ahead and plant some more seeds.

There might be more than one problem going on with the tomatoes, given the various spots and leaf curling but there seem to be some burnt edges on the leaves that might indicate fertilizer burn.

I'd go for perhaps a mild soapy water spray if the neem oil doesn't take care of insects. 1/2tsp. dish soap to a quart of water - stronger is NOT better and may make the leaves photosensitive. So rinse the plants well after doing this.

Ohh ! Johnny Johnny Johnny !😬!
I dont know how much water there getting each time you water them. But ! It sounds like ground is constantly wet. Perfect environment for fungus gnats. I'm pretty dog gone shure thats what you got. You've got to get rid of them. Read up on killing them. To much to get into hear.
Watering ownce a day could be to much. I know ! I learned the hard way. The dudes prety much won.😑
I'd fertilize 1/4 strength ownce a week, after plants have true leaves.
