Burnt leaf tips - Potassium deficiency?

Discussion in 'Sick Plants and Problems' started by jus_chillin, May 21, 2010.

  1. At 8 weeks you should start seeing yellowing a lot from the plant using up the last of its nitrogen before death. You are just fine.
  2. But the leaf tips started looking burnt around week 5-6.

    I know the leaves turn yellow as nitrogen is used up near the end of flowering (as this was apparent with my last bubba kush grow). However, my last grow didn't show the same leaf tip symptoms.

    Any ideas?
