Hello Fellow Growers, My name is Skanky. Im relatively new to growing. This is one of my first grows. Im growing 1 plant, Keeping it inside under 1 Light Just to start ( I know its not alot, But i will upgrade to 3 shortly). Every 2 weeks, I go to my dads house, So I have to leave them outside for 2 days. They do fine and all when i come back. I water them the day before i leave. I usually have my plant inside a white box inside my closet. The light sits about 4 inches above the plant. A couple days ago, The leaves were perfectly green, But also a couple days ago, There wasent a 3rd set of leaves growing. All im here to ask is What Im doing wrong inorder for my plants to turn yellow.
