my plants are fruity

My plants are producing El Perfecto, but my question is - since the plant can't go back to grow stage from produce can l run my lights 18 hours a day and there will be adverse affects to my fruit maker ?

Whhhhat? Why would you do this? It will eventually revert back to veg but whhhhy? It would be alot easier to take a few snips off the base n revert the clones back to veg n let your hoe finish then toss those clones into flowering once they've grown a but n next time take some cuttings in veg as it causes less shock n theyll root faster.
