Help with my Tomatoes, Zuchs & Cukes (Greenhouse Gardening)

[Sela]

I have planted Cukes Zuchs and Tomatoes in my greenhouse.
Now, one tomato plant is doing wonderfully (It was originally in a 4 inch pot when I brought it home & transplanted it) however my bedding plant tomatoes Zuchs and cukes all look wilty and curled/furled and ready to croak. (They are constantly either having leaves die or just dropping leaves)
I have put some 10-10-10 all purpose fertilizer in the soil and water when they look like they need a drink but - they don't seem to be doing well at all.
My melons carrots and spinach and grape plants seem fine as well (healthy)

I live in northwest BC (Canada) and it's warm here so I leave the doors/windows open at at all times - it's also quite warm/hot during the day...
Do you think this could be the temps?
or
What could be another problem to look for?

Our tomatoes and cukes are all outside, but have all been grown from seeds.

our tomatoes are doing incredibly well [theyre in a 'garden' far away in the backyard, and we never watered or fertilized them] theres not even been much rain; our tomatoes are puzzling to us lol. the only fertilizer of any sort was dumping a bunch of grass clippings on them, maybe it helped.

our cukes are so-so. some are wilty, some are great. once again, rarely water. but for fertilizer we put some miraclegro at the beginning when the seeds germinated.

dunno if any of this helped, but hope it does

we live in michigan btw. it gets really hot during the days [85F - 90F] so I don't think teh temperatures are the problem. Considering how far north you are, what temperatures are you getting. it might not be warm enough?

Thanks Ces,
Dunno what the prob is..Is been really hot in there during the days (Outside temps 30+ Celsius) which is why I've left the doors/windows open all the time and the night time is T-Shirt weather so I don't think it's too cold...but who knows..this is my first greenhouse. I thought maybe the cement base ingredients might be leeching into the ground or the tar paper to protect the 2x4's that is slightly touching the edge and has had water trickled onto it occasionally and into the ground slightly might it. But my one healthy plant is right in the corner and next to both of these elements...so that can't be it!

I don't think I will put them in the greenhouse next year if this is what's going to happen again...

Yeah no idea, never dealt with a greenhouse before

Hopefully it turns out right

The ole southern growers have a name for what you described, it is called "the wilt". Yup, just like it looks. It affects the soils in which the plant roots reside, it is either fungal or bacterial as they decompose it spreads very quickly thoughout the soils. "Nary a tomato will ever be healthy in the soils for two years following the wilt.." is the saying that goes with this plight. If your plant is potted, dispose of the soils far away from any place that you might want to plant a tomato next year.
Cukes will rust, brown and have stem rot if touched or moved. Never try to force them to vine differently than they decide to climb. Left to their own device they will profit pounds of cukes per plant, but cukes & watermelons HATE to be directed and will rebel by drying up.
If your night temps are alot cooler than your day temps, then water your veggies in early morning. If the nights are steamy like days are here in the south then water them several hours before dusk but never when the sun is high in the sky or before noon or the roots can cook.

OMG! - well that makes so much sense as I never used a/the greenhouse before. After my hubby built it in the fall, the area where the soil is encased was covered by plywood boards and "things" stored on top of them for the winter. I didn't do anything to the soil beforehand - I just started planting plants after removing the boards this spring.
Do you think there is a fungicide or antibacterial I can add to the soil to freshen it?
Thanks "maLady" am going to look into this as a friend said they had this happen one year to them as well.

This year there is not much hope. Consider that you will want to eat the veggies. Would you really want to use chemicals? That said, just nurture what you can from the stunted plants. You might get lucky and have parts of the plants be hardier than sickly parts. Prune the dead foliage, but do not feed them back into soils, throw the sick limbs & leaves where you do not plan for anything to grow.
I'll tell you what I do, but it can be dangerous and requires two people. We have a butane torch. We til the soil up, then while one of us stands near with a garden hose, the other torches the soil, the one with the hose has a hoe and keeps turning the soils as the other torches. It must be a day that is air is still, no wind, careful of flames from the butane torch not catching fire to surrounding weeds or grass & spreading.
Torching the soils is good, it kills fungi, bacteria, seeds that would grow grass/weeds, grubs, nematids and other unwanted pests. It's bad because the soils are rendered sterile & lack nourishment so we then mix some peat, some manure and some lime and hoe it all about.
I don't water it with the hose to make it muddy. I just wait a few days before I plant seeds, bulbs or transplant plants.
