@SilverDutchman, you probably did not overwater but you watered too often.
Im growing the same thing btw. I noticed it says “can be flowered at any period of 12-18 hours.
To me it does not sound like an auto.
And i will as of right now jack my time to 20 hours of light per day.
I dunno 2-3 weeks of veg for this. Will fuck up my schedule for sure.
