Yep RT gets another one....I gotta start getting here earlier! This is a reaction to the stress from trying to go back to veggin and is quite normal, although it can mess with your mind (wait a minute! That WAS a cannabis plant...WTF is it now?)...give them a few more weeks of 18/6 minimum, and they should straighten back out and go back to normal leaves....
RT, I like the new phrase....WLS....PERFECT! That's what we should call it! Seems to be a very common event when re-veggin, so from now on I will call it WLS! Nicely done!
