Default Interactive Program for Tomatos and Lettuce

I found this to be very interesting for anyone that's growing tomatoes or lettuce. I put in my numbers for the tomato plants I'm growing and it says I should increase my nutrient levels but everything else was perfect. Check it out for yourself. Just put in your numbers and see what it says. Would like to hear what everyone thinks about it after seeing what it says. Here's the site.

Mine was saying I needed to get between 2300 - 2800 PPM to be in the green from top to bottom. So far I have only gone as high as 1500 PPM but I did read on another site that tomato's should be between 1400 - 3500 PPM depending on what growth stage your at. If I were to get my reservoir up to those numbers I would have to add 50% more Verti-gro nutrients than what is suggested on the package.
