Strawberry Banana auto 2021

Not much sun this week but they grow like being on Viagra!!!!! The lady in my garden is 71 cm and is slightly starting flowering. The two ladies at my sisters garden are 77 and 78 cm and start flowering a little more! All 3 are exactly the same age! Because all growing conditions are supposed to be the same (genetics, soil, pot size, rain water, climate), the difference in length must be explained because of the exposed sun hours a day! At my sisters garden there exposed more hours to direct sunlight. Does anyone of you know if a mutant plant that makes no branches, still is going tot make one big cola if it's gonna turn out to be female? I wonder if my Sherbert Gelato thats growing guerilla style, has any chance at all??? It seems not to be an autoflower and I got this seed out of a bag of awesome Sherbert Gelato I bought last year. The bag supposed to be sensimilla but there was one seed in it!? Like to be very near the flowering stage, next week probably pics of the first little buds! I'll think I'll start adding flowering nutrients after next week! Grtz✋ and if you know something about the mutant let me know!
