Canuk Couple First Grow

They're really kicking into flowering now. I'm still keeping the nutrients going strong but I think the last feed may have been too strong. That's a cause of downward pointing leaf tips, right? Cheese is smelling great and producing tons of long white hairs. She shot up like a stick over the weekend so I bent the top portion over to flatten the canopy out a bit. Cookies is trucking along like a trooper and smells almost minty. I defoliated a good chunk of the lower brush to improve air flow and maybe prevent bugs. I'm contemplating lowering the lights but both plants seem to be doing fine where they are and I don't want to wreck a good thing.
