  4. To confirm the guy above take a photo of the main stem and a leaf stem on the top most branch
    If it's purple it very well could be mag
     
  5. I also believe it to be magnesium defiency you need to maintain you ph level because if it is at what you say it is your plant will not get as much nitrogen, phospherous, and mag, as it needs (in soil at least which is what you appear to be using)

  6. Ph 5.8 is definitely too low. Adding Garden lime will help.

    Hope this help

  7. 5.8 is good f9r hydro..soil needs to be 6 to 7..

    Nute burn will show up as yellow on your leaf tips..which is what I'm dealing with..gave a low low dose but I think I was too early..
     
  8. I gave her some domilime witch makes the ph goto 7. The stem are purple. Here some up dated pics

  15. I'm going todo a foiler feeding
     
  16. Now like 2wks later the ph is 6.5 with nut and 6.8 with water the drip. That leaf is now purple. There is growth but not 100% correct leaf are skininy. I purchsed biobizz fish mix and An conasur. With one is a better idea to use?

    what kind of light are you using?
    How far apart from leaves
    What the temperature in there?
    Too hot or cold also cause stem to turn purple.
    Now it Sound like a light burn to me.
    Check out the leaf of light burn.
