Does this look like light stress, currently in week 1 of flower had flipped 12/12 on Friday. Just increased light intensity from 50% to 75% now leaves are yellowing
Disclaimer- Old eyes and defs not the best at identifying deficiencies….with that said- serrated edges can go wonky and/or twisted leaf tips are signs often associated with light stress. New growth comes in with a lighter shade of green so overall they look pretty groovy right now.
Maybe they could use slight bump in feed… What are you feeding them?
looks plain hungry. could be other stuff happening but there aren't enough details to tell really. hope you get it figured out, they can crash fast after flip if you are off on something.
