could someone tell me the right tds levels for young plants and the tds level for adult and flowering plants.
I have a TDS meter. I have a deepwater set up. When the plants where young but growing and had about 3-5 solid nodes i was around 250-300ppm Now my plants that are 3 weeks into flowering i'm around 800-1000ppm. I keep my ph balanced around 5.9-6.2. I hope thsi helps what u have yours at? I also use a 400watt Mh for my babies and 1000 HPS for flowers
I just ordered one off ebay for 20$ free shipping. says it reads ppm from 0-2999. I thought 20$ was a very reasonable price
