Upward canoeing leaves? Please help

Discussion in 'Growing Marijuana Indoors' started by MadamGanja, Oct 21, 2014.

  1. I noticed this morning that the upper leaves on my largest plant are canoeing upward. Can someone help me figure out what this is? I believe the plants may need more nitrogen, due to the yellowing of the bottom leaves on my larger plants and a yellow spotting on one upper leaf. This is my first grow as I havent had my card long. Help? :c

     
  2. Upward canoe is heat stress, lift your light up higher or get some extra airflow, or both. Need pictures to determine what's up with the yellow though
