So I've done soil, DwC, aeroponics a couple of times. I am attempting the NFT system for this first time and my kids are two weeks old and are getting yellow tips from nutrient burn. I'm running Advanced Nutrients Grow A and Grow b for veg and Bloom A, Bloom B for flower. Also using an N CAL MAG with H2O2 oxidizer. My ppm is around 200-300 right now and the PH is at 5.5-5.8 Temp gets as high as 88 and as low as 55. I have an air stone is my reservoir. I'm going to SOG train them as we'll.
Im just wondering if there is any insight that I'm missing. I'm a little concerned that my roots are just out in the open, I don't have a cover for my 3x3" tray, (should I get one?). What can I use to make my roots nice and strong?
growing with a 1000 hps and an LED light I made with a PAR of 770 in the red.
any thoughts? Ideas? Suggestions? Problems you have came across with NFT?
