My plants' stems are getting progressively more purple and I can't figure out why. I have already looked through all of the nutrient deficiency stickys without luck. A little background on this grow; I was burning the plants for the last two weeks by using the nutes at full strength AND using tap water. I am now using R/O water and 50% strength on the nutes. If you would like to see any other parts of the plants or close-ups, let me know and I will post them. Thanks for reading.
Here is my setup and environment:

(the plants actually a little deeper of a green than the pictures are showing, probably because of the light)
Here is my setup and environment:
- 1000 watt metal halide light on 18/6 schedule
- Undercurrent DWC hydro system
- R/O water (PH @ 6.2 / PPM @ 0)
- House and Garden Aqua Flakes A & B nutrients at 50% strength (currently at week 2 veg)
- Water Temp at 68 degrees
- Air Temp at 78-80 during lights on and 68-70 with lights off
- Relative Humidity at 40-47%
- PH at 5.8-5.9
- PPM at 320 (3 days ago) and 340 (today after bumping up nutes last night)
