So I'm growing tomatoes and jalapeños in a simple bubbler setup under CFLs and tubes. I was wondering what the PPM should be like for these plants. They are approximately a month old. As of yesterday the PPM in the water is 2200. I am using Botanicare's liquid karma and grow.
Will these plants show nute burn like MJ will? If so, would it be wise to give it a full dosage of karma and bump the grow nutes by like 100 every other day until it shows a little it of burn then add some water to back it off?
Heres a pic of my setup
