Well, when I grow tomatoes I just use a liquid tomato fertilizer using a low PPM until established and then just follow the dosing instructions on the bottle, checking PPM to make sure it is not excessive. Don't wast your expensive nutes. Get a cheap bottle of liquid tomato feed. You do not need to treat tomatoes with the same TLC as cannabis, unless you grow hydroponic.
Just treat it like a garden plant and follow the instructions on the bottle. Don't waste expensive pot nutes for a normal plant and tomato fertilizer is designed for a food plant. Won't leave chemical taste in the fruit, unless you really over do it, and is safe for human consumption...But I would not drink the stuff straight up.
