  2. Depending on the strain it could suggest low Cal/Mag. Photos?

  4. Buddy of mine told me that if I ever want more dense and purple weed to just give it cold water overnight

  5. Maybe your watering source is too cold for that particular strain?
     
  6. Definitely no way since my other plant is straight green no purple and i give them the same stuff

  9. Sounds logical. I definitely know that when the weather turns colder in flower that certain strains turn purple. This is last season. IMG_1811.JPG

  10. Yes cold at night can turn them purple, that part about density is wrong tho.

  12. How much sun are you getting? Here in Hawaii sativa stems and branches tend to turn red / purple when in heavy UV sun.
     
  13. Almost all day

  16. Your plant is fine. You were talking about the stem on the fan leaves? Because that it normal.

  19. Purple stems and petioles do not have anything to do with cal-mag issues and are not a symptom of calcium or magnesium deficiencies. Cal-mag deficiencies start at the older lower leaves and cause brown spots and leaf chlorosis; not purpling stems. Your plants are fine, leave them alone. Stop adding Epsom salts and cal/mag or you will cause a lockout of other necessary elements needed for good growth from a mg toxicity from the excess cal/mag or Epsom salts.
