Dont worry man, its just your plant expressing some colors on the leaf tips. I was looking at the diary the leaves look kind of wavy. i would be more concerned about that. Try to ease up on your wanting a bit. i saw them clawing downward too. overwatering is one of the easiest things to do even for experience growers at times. Overwatering happens when not giving to much at one time but too may time without enough dry time in between
