Hypothetically of course, When growing from a bagseed, if at 10 weeks into flowering and about 70% of the hairs are brown and the grower had provided a plant with 24 hours of darkness; what does it mean when the plant is checked in on more white hairs have sprung up. What would the best course of action be? Should the lights be turned back on?
at 10 weeks, i would probably chop it. Even when a plant is ripe, it will produce new white hairs, just not a lot of them.
Would their be detrimental effects if a light cycle was resumes? Rather, how detrimental would the detrimental effects be, lol.
When you play with light cycles you risk hermaphrodites, but since you are so close to harvest, you could just pull the plants if they turn. So, i'd say... do whatever you want, just keep an eye on them.
