Hello my name is mike new to growing

Fix it before I flip it to flower
Thanks
Growing indoors
Fox farm ocean soil
fox farm big grow & big bloom twice a week
Unknown strain
As long as its just the large lower fan leaves don’t worry about it as its normal, if its the majority of the plant and/or including new growth then you’ll want to wait to flower to address the issue. Other than that I’d say she looks nice and healthy, some leaves I can see in the background look really healthy (ribbed looking leaves) i think you can flip to flower when your ready bro! Happy growing!! Welcome to the community @Twist!
They look real good, nice job! As @209MIKE says, the yellowish leaves are normal.
Just keep doing what you are doing and welcome to the community @Twist!
