How much water do you give her ?? Does she have some pest ( aphids)?
I’ve notice in the past that little to much water and having aphids can turn your plants in that mess ....last time it happened to me I’ve removed lots of large leafs to help get more sun and I stop watering her for a week and problems solve!! Marijuana love water but it à plants from dry country so thoses not need as much water sometimes
( just my opinion)
Best of luck and happy growing
