this is an interesting observation. do you mean individual leaflets twisting ends at a 45 degree angle? or the entire leaf rotating on the petiole?Just switched to jacks a few weeks ago, so far so good! Been watering 5 gallons at a time, 18g part A, 6 grams epsom salts, and 12 grams part b. One thing I've noticed is that some of the upper fan leaves seem to be rotating to be on like a 45 degree axis. Any idea if something in the new feeding schedule could be causing this? Its the only variable I've changed lately. Thanks!
