Im growing a heirloom brandywine from burpee and also a jubilee - yellow tomato (I think). These plants look healthy and green. I have been pruning the lower leaves also. I has been about 100 degrees or more daily. I have the fruit either aborting and dropping on the brandywine. The brandywine is still growing and producing more clusters and flowers. It doesnt seem to be stunted. But leaves are wilting inward. Like if you "cuff" your hands. A little curl.

I have my first cluster of flowers on the jubilee and the flowers are starting to open on them, so I will have to wait to see if these flowers dont pollinate also. This plant appears to be twisting. The older leaves look healthy, put seem to have a odd curve to them. The top is really curly and a few small branches do complete circles and twist. This plant appears to be stunted and is growing much slower than the brandywine.

I have an automatic drip system that waters the plants for 2 mins @ 7am, 12pm,4pm,8pm with 1.2

I using a "Dutch Bucket Hydroponic Drip System". A soil-less system. Rockwool, perlite and hydron rock.

You can find my photos on my flickr account for more details.

I figured its the heat and the genetics might be causing this?

Thanks!
