So basically I think i under watered the front one and over watered the back two. but I'm not quite sure some of the lighter colored leaves are flipped over from a fan blowing on them but then again some are a little yellow. every time i watered the dirt was dry when i stuck my finger in it but i never used the lift the bucket method until recently. This is how i concluded that the front one was under watered and the back 2 overwatered. the front bucket was light and obviously the back 2 heavy. I'm knew to this so take it easy on me hope i didn't kill them ..
