Special kush + amnesia (auto) outdoor

Fourth week of vegetation, over!! Better sunny days, not too much wind and no rain at all made them grow a lot since last week! Almost doubled their sizes. The amnesia auto has officially initiated the pre-flower! Just in time as RQS marks on the schedule, it has stretched a lot and the stem is getting stronger, also pushing side stems from the central one so I expect her to continue growing a lot! The Special Kush stretched not as much as the amnesia but anyways a good week, growing a lot their fan leaves! I don't know how much time left for initiating flowering period, it's making me doubt for topping her or not but I think it's a little bit too late. Irrigated both on them with BioBizz Bio-Grow, next week the amnesia will start with flowering fertilizers
