I have been told they are made to be low salt nutes. I use about 1 tsp per gallon, the grow is very thick (like Molasses), I haven't used the bloom yet because I have been growing veggies that don't bloom, i.e. lettuce, spinach and celery. So far I really like Floranova, I like the 2 part mix instead of the 3 part mix. I also have the Floralicious Plus and the KoolBlooms.
I just started some green beans, a tomato, and a pepper. I will let you know how it turns out. You can watch it on my
Hydrocam
I transplanted the beans this morning and they are only about 3" high now.
