Marijuana Plant Abuse
postmandave Reviewed by postmandave on . dull green foliage ive got a little problem that i cant seem to find an answer for around here. maybe i just have an inaccurate description for a common problem. everything seems normal on my plants except the foliage is dull green. it looks "ashy" like they need lotion. a friend told me its because the oscillating fan was blowing directly on them but it doesnt look like wind burn. pics dont really do it justice so i havent included any. any ideas?
