@stick autos really depend on light not so much time adding light from "too little" to "enough" will surely accelerate it's metabolism and get it going... see one of my grows my auto was getting basicallyy 2.5 hours of light a day ... it took 25 weeks ! anyway, for what it's worth, you're 100% on time and completely inside the average for the preflowering that you're seeing. It may have been a trigger putting more light in, but I don't think it really affected the timing much ! hope this clears this up for you ! good intuition you had ! 🚀
