Decreasing light intensity last weeks

Don't do it buddy you will yield less most likely as light in these stages bigger the better the more light absored by the fans the bigger your buds are going to be. I assume your thinking if you lower the lights it may act like the dark period towards the end of a grow when growers will leave plants in darkness for 48-72 hours before harvest this is to try and mature the trichomes abit better making her stronger. though at this stage I think she would be missing out on energy if you put the light down :) best of luck buddy they are some beautifully trained plants well done :)
