I am new. I am having some issues with my leaf's. I am not too sure if its over watering underwatering not enough nutrients? someone said its old growth another said it maybe a potassium issue. I have no complaints I am growing something getting some results I am happy. on the other hand I like the time and effort to grow if I am going to grow I should try my best. I will add the photos to my girl. I am here to learn so any help is a blessing.
