Can I use this on pepper, bell pepper, pomegranate, citrus and lime plants other than tomatoes?

I used this in the water reservoir on my Earthboxes.I grew tomatoes and peppers and it worked excellent. It curtailed the BER and seemed to make the plant stronger.

Would this take care of blossom rot for watermelons?

Blossom-end rot is a nonparasitic disease of tomato, pepper and watermelon. Losses can vary from a trace to more than 50 percent. The first symptom is a slight water-soaked area on or near the blossom end of the fruit. So using Calcium Nitrate should help with your blossom end rot problems.

Is this for use in addition to a plant food or alone? If I use this and a seperate plant food will my tomatoes get too much Nitrogen?

Well, if you have the master blend combo (Master Blend, CaNO3 + (NH2)NO3 & Magnesium sulfate), then you've got everything that you need. If you’re just amending with Nitrogen because your leaves are turning yellow from bottom upwards and that should be the only reason you feed such hgh amounts of N to anything but lawn grass. Ideally you want a 7-7-14 or you can put something together for yourself. Find the GCF between 3 fertilizers and you handle it like algebra to figure out the NPK for all 3, mixed.
