stress

Leaf down too much water.. Browning on tip of leaf too much nutrient ...leaf tip reaching up light too far....holes in leaf 85% of times its pests of some kind.. You'll have to inspect the under side of leaves and check soil for fungus or mildew.... GOOD LUCK FRIEND👍👍💪💪🍻🍻🍻

Listen to the g slave my man

hello my friend most do not train auto flowers because any stress you cause them can add weeks onto your harvest time it can also effect the yield in a negative way the reason is autos have a predetermined life cycle meaning any stress you cause her will take time off her in built clock forcing her to work harder to repair from the stress when she should be concentrating on growing. My advise would be to untie her and just let her go. If you want more yield I would look into the pony tailing method of training this does not stress the plant no where near as much as LST does :) Best of luck my friend keep up the great work :)

If your worried of a little droop that is usually caused by over/under watering. Your girls look fine to me. Heat light stress turns the tips of leaves a little bleached, pale or yellow and the spreads inwards on the leaf affecting the outer edges first. Cheers
