This started a couple weeks ago and is affecting all of the growth on just one lady among others with the exact care/environment. Everything looks nice and healthy other than the curling on all the leaf tips. No burning, just curling. Some are upside-down cupping, but nothing is too severe, yet.
70's-low 80's day/night, 400w mh @ 12-15" from top, nutrients don't seem to be an issue, but could be wrong. Using straight water for the next few feedings. Didn't do a soil test yet.
Excuse me if this has been posted a zillion times here, but since the symptoms are so similar to many problems I thought a pic might help be pretty specific as to what's going on.
Ideas? Thanks.
