  2. I dont know the problem/solution surf, but i sure know i have the same problem!! Ill be following along if you dont mind? Cheers :)
     
  3. What water are you using?
     
  4. Try using Supernatural's Ultimate thrive with it. Its extra micro and macro nutrients. Whenever ive had deficiencies i just toss the UT in and it always helps. 5ml/gal is all you need. UT also has more nitrogen too! its a 5-0-2

  5. Looks like a magnesium def. either caused by lockout or just not enough mag.

    You should let the pH drift up more, especially when you switch to flower (for phosphorus). Magnesium is more available at 5.9
