Hi! I will start my second hydroponic system (DWC) soon and I would like to cultivate tomatoes. Searching the web for the correct EC values I found many tables like this http://www.homehydrosystems.com/ph_tds_ppm/ph_vege... Well, I don't understand if the range of EC values refers only for the fruiting phase or also for vegetative and flowering phase. Some help? thanks a lot!
i couldn't really answer that plus I'm not growing anything so idk how seriously id take my input if i were you but what i would do is start with a weak nute mix and adjust it as needed and find the ec for yourself this link will explain what I'm saying https://www.420magazine.com/forums/how-to-grow-mar...
That table says to have the EC at 2-5 mS/cm which is very high. I'd start with much lower and keep testing every day to see if the reading goes up or down
