Should i do something with that leaves?

Your plant looks great bud but the one thing you don't need to be giving her right now is the bud candy. I would drop that until bloom. The edges of your leaves are just lightning color, not burnt.

Over fed/nitrogen excess...........feed less........simple!

Lower EC a little 0.2

looks like slight nutrient burn. Make sure you are mixing the nutrients in the right order. Micro.grow and bloom in that order. The boosters after that. You could have salt build up in the root system from not feeding with enough runoff. I would do a flush then continue with feeding. Good luck with your grow.

I haven't used your brand of nutes for quite a while but your Ec seems OK at 1.2 maybe would have been better nearer Ec1.0, I'd be tempted to lower the PH to 6.2 from 6.5. Other then that she looks great.
