Hello all, this is my first post on here, as well as my first grow. I know I jumped into somewhat advanced waters (no pun intended) by choosing DWC as my first grow, but that's just the way I am.
Anyway, I have a small space to grow in. 5 feet tall, 4 feet wide, and 2 feet deep. Inside are two, 6-site DWC tubs that are homemade, a 400W HPS w/ 6in. air cooled hood. Each side of the hood has an 80cfm in-line fan. The room itself has one 80cfm fan pulling air in the bottom, and another pulling hot air out the top. The room stays at 78 degrees during the day and 70 at night (Fahrenheit).
The tubs have 8 gallons of RO water in them, with an airstone and aquarium heater in each one. The water stays 69.8 degrees F. The pH stays between 5.5 and 6.0. I am using Cyco Nutrients Grow A/B (NPK 6-4-4 combined), and supplemented with Cal-Mag. PPM reading of 550 (3 TBSP nutes, 70ml Cal-Mag).
I currently have 8 plants growing (all from clone). 2 Blue Dreams, 2 Jack Herer's, 2 Skywalker OG, 1 Casey Jones, and 1 Pandora's Box.
Below are some pictures of the problem plants( except for the healthy Blue Dream in the 3rd pic), I hope you all have some advice!
