Default Help?: Hydroponic Tomato Problem, Pictures and Log

I'm new to hydroponics and I seem to be killing my young tomato plants. Here's my setup: I have an ebb and flow system (greentree hydro) to be exact. Hydroton medium. I'm doing it outdoors fueled by sunlight. The information I came across said that tomatoes ideally like and E.C. of 2.0-3.5, and a ph of 5.8-6.3 and a 50 gallon reservoir temp of 65°-75°.

I'm using general hydroponics maxigrow for the vegetative state of the plants. I seem to be killing them. I'm wondering if my nutrient levels are too high for the age of the plants? The E.C. is between 1.5 - 2.0. The PPM is 1000-1400. My PH has been around 5.5-6.5.

I started my seedlings in my Aerogarden and I tested it and the PPm was at like 5000 and they were doing great in there? It has me perplexed, I know the aerogarden is dummy proof, so I am assuming the nutrient levels can be high there but very mild so they won't burn the plants? Can anybody help? I posted pics of plants below. They are not before and after, they are two different plants as well as my log of what I've been doing. Thanks in advance.
