Simple question appreciate help

Ok my lights come on at 3am and stop at 9pm wud it be ok to change to schedule to 6pm to 6am
Also one of my plants leaves tips are curling downward

your going from 18 to 12 hours there should be no problem...

Yeah you can do that. They tell ya not to change the time that your plants wake up, but as long as you don't fuck with your plants light cycle to much you will be fine. Just do it once and call it good! A plants likelyhood of going hermie on you is in the genetics, if you have good strong genetics you should be fine.

Cool thanks man +rep for ya
