Trouble Getting Started
We recently built a NFT system using 6" PVC and net pots for tomatoes. We are using and 18 Gal tub with lid for the reservoir. The first go-round was an absolute bust with too many problems to list, long story short too many nutrients, no aerator, root rot.........
2 days ago we broke the entire system down and scrubbed each piece with H2O2, re-assembled, and started over with 18 new plants(tomatoes and peppers) and even new clay stones. Treated the system with Hydorguard and are currently running 2 air stones(5 inches each).
As of a couple of the plants are totally limp. No yellowing yet. PPM base line was at 225, using Earth Juice Grow, I brought the PPMs up to 400, 550 the next day, and today they are at 722, Ph was adjusted yesterday and is at 6.0 today.
