    So the lights spot it yellow
    Also on another leaf the end of the leaf is turning light green
    I see closely on new growth im getting funny lookin parts
    Like brown dots

    Can someone help? It's 2 weeks old 200 ppm
    5.5 on
    79 room temp
     
  2. Ph is actually 5.9 not sure why it rose either
    Was at 5.5 12 hours ago
     
  3. What nutrients are you using? How close is the light and how many watts? Circulation?
     
  4. Using Lucas formula
    9 inches away
    Plenty of curculation
     
  5. i dont see anything wrong?
     
  6. That is a magnesium deficiency, raise your pH to 6.3-6.5 and it will clear up [​IMG]
     
  7. are you positive this isnt a soil grow chart? i thought anything over a ph of 6 in hydro will start to cause lock out on certain nutes
     

  8. this is a hydroponic grow. Keep your Ph 5.5-5.8
     
  9. increase nutes
     
  10. I did increase nutes to 500
    This weekend or in a couple days im gonna increase to 700
    She's taking off now and looking beautiful
     
  11. stick with 500 for awhile
     
  12. You need cal-mag, come on people.
    If your in dwc stay at 5.6 5.8
     
  13. no cal/mag
