help with ID

[Glen Bryan]

I could use some help with a diagnosis. They are in a greenhouse in a hydroponic system. I thought Tomato Yellow leaf Curl. I have had white fly this year, baby sitting some Koi so i have had to be less aggressive with the spraying. The thing that makes me wonder is that the leaves look fine except for the curl, no yellowing etc.

Thanks
Glen

What variety?
Is it hot in there? They look stressed to me vs diseased.
