flower stage help?

hey everyone i have a 6 week old plant and is ready for flower but i was wondering if i can just switch to 12/12 after 6 weeks of 24/0 light cycle or will it be to much stress and do you start feeding right away?Any input would be appreciated.

switch away! I find that the sudden 24/0 to 12/12 light switch helps them show sex faster. I have no scientific data to back this up, just my own experience.

id go with bam and u should probly wait a week to do first feed because u may still have nutrient left in soil and u wanna use it up first u dont wanna deficiency or over nute u know
but yah yur plant will say hi to 12 12 and start showing sex so as he said switch away

already thanks everyone this helped.
