The tips of leafs dropping
I just upped the nutrients a little but still under what the bottle says( I'm using micro bloom grow)
Not sure if it over watering or what any advice?

Dude over-watering ? looks a little dry to me. Also pay more attention to new growth, i see so many people overly concerned about older growth, good luck... and i f i have to tell another person to lay off the nutes im going to scream!
