My plants look pretty much the same with the top leaf curl. Im new to this forum, so Im going to post a little bit about my system and setup. Im not trying to steal you thread, but rather extend it.
I have a Jubilee (I think) and a BrandyWine Tomato growing in one bucket. I established the root system very well before I transplanted them into the bucket system, so there should be enough root to expand, and the roots not get too crowded.
These picks are of the Jubilee Tomato.

And some leaves:
I have 5 & 3.5 gallon dutch bucket
drip system. I live in central Florida, so the temps have been reaching 105 degrees for long periods. Then some days the extreme heat will be followed by extreme storms and humidity.
On the "curling" plant that is pictured, this plant is currently flowering and it looks like a couple made it through and pollinated.
This weeks pics of curl and flowers:
I have a 26 gallon res. and I keep the Floramato
nutrients at about 1.2-1.4. I have been using tap water. I run the nutrients @ 8am, 12pm, 4pm, and 8pm on variations of 1 and 2 min runs. (More in the afternoon heat) Im thinking my nutes are too low, because I read your blog that you where using 2EC and that was too high. (I havent checked the temp of the water, but its in the shade and as cool as I can get it.
I have an air
pump, but I only run it for a few mins a day when I get home b/c it gets too hot for some reason. The pump is inside the house and is pumping cooler air into the res. I dont know why it gets hot b/c its brand new.
The
nutrient runoff is recycled, but there is a constant 1.5'' of nutrients in every bucket. I have lifted the bottom bucket out of the top one to check the roots, and they havent yet reached this water.
I started them in rockwool 4'' x4'' cubes and transplanted them into a bucket with hydron rock (bottom 1'' layer) and perlite (top layer).
More on the Greenhouse Environment:
I built a outdoor hydroponic greenhouse - allowing some bugs and not 100% sealed. I built this out of an old carport and used one have of it for the greenhouse. I screened in the sides and put greenhouse poly film and 50% aluminet shade cloth over it with wiggle wire to hold it secure - but also easy to take off to clean. I also had to add the aluminet shade cloth to the sides because it was getting too hot. Compared to how hot it gets without the poly and shad cloth, its about a 10-15 degree difference.
I installed a misting system at the top of the greenhouse, but it is not yet functional. I need to buy a incremental hose timer to run for 30 secs, every 5 mins or so during the hours of 11am-6pm. Once I get this working, the temp should drop from 100 degrees to at least 90, hopefully to 80-85.
My guess so far has been then heat. Ive had little flower flower development, and the they looked stunned for a while. But Im getting more what looks like fruit development on a couple plants.
Let me know your thoughts....thanks!
