If it were me I would drop the light like Hulk said, and depending on how high your grow area is, feed it some bloom nutes and in about a week I would defol all those big fan leaves and flip to 12/12. Depending on the strain it may double in height in 2-3  weeks after the flip and nobody like to super crop after flower has started just because the grow area is short. 

Count on double the height in the stretch but plan for triple and you will be ok
