nice, i'll have to help you identify any MS plants i have a little later on, i don't think i have any flowering yet, the other 3 i have flowering right now and one of the others i pictured, i have no idea what they are like i said. I'm sure once they finish i'll be able to tell. Also i think 46 days would be still pretty early for KF even if it really is an earlier pheno. I would probably let it go for another week before i started getting a scope if thats how you check. I usually just take a small nug here and there and keep track of when i cut them, then let the plant go until i know it's for sure ripe(obviously not overripe) then harvest it all. If you find yourself enjoying any of the buds you cut before the full ripe harvest(if it's too much for you) after it's all done and cured then you know exactly when to harvest. I don't use a scope much, I will if it's my first time with a strain, but after that it's pretty obvious when they are done if you pay attention to them. I think people get too worried about the exact % of amber and all that. Do it a few times and you know pretty much the day your going to chop the day you put it into flower if you don't make changes to your procedure.
