Tws I agree. medi, I have been growing in nor cali for multiple years and I can promise anything going from one extreme to another extreme, such as ph levels going from super alkaline to acid 8.0 to 1.0 will force it to be a herm or bloom, stress like cutting off hella branches, Or doing a super high stress training. Topping the plant (fim super crop) while doing lst (bending hella branches at once) or going from 90 degrees to 40 degrees in a day, will for sure trigger it to flower. I have seen it happen before. Sure light is a HUGE factor, but it is close minded and single sided to believe that only one thing goes into the factor or your plant possibly flowering early. Climate, geographical location, humidity, stress, strain/genetics, amount of water, ph. I can go on.
