GreenBrian,

Previously I have used Ionic Grow and Bloom on Tomatoes. My results were positive and I can't say anything bad about Ionic. My experience has been that most synthetic nutrients are mixed from roughly the same ingredients and it's not worth losing sleep over which brand you will use. Some nutrients now contain additives like thiamin and humic acid and those offer benefits though it's debatable as to how much extra it's worth paying for.

My understanding is that organic nutrients work fairly well in a run-to-waste system using coco coir as a medium, have you considering giving this a try yet? An organic nutrient you may be interested in checking out the organic nutrient line from Biobizz.

General Hydroponics Flora line is working great for mine. I might try their tomato specific nutrients next go round, though, just to see if there is a difference.

thanks bilberrybrian and joe.jr317
i have heard of both, i was leaning toward g.h.
flora nova line, didnt know they had a tomato
specific line, i'll have to check that out, somebody also mentioned dutchmaster products, anybody ever try it?

I use AN's Sensi 2-part myself, but AN makes a whole organic line specially designed for hydroponics if that's what you'd like to do.

Here's a link to all their stuff, the organics are on the upper right.
