If your strawberry banana was a FB, then I’m starting to notice a trend in FB in my tents. I had similar issues with Zkittlez. And the zkittlez is one of my favorites to partake of.I had strawberry banana in a 7gal looking about the same. I think that some plants don't like to be trained as much. I had some other plants I trained the crapp out of where the lower buds were huge and rock hard. I am asking myself questions as well. Next time I grow it I will train to a limited amount of tops.
Almost like every FB I grow wants to foxtail, or at least looks like it’s on the verge. Never had the issue with any other seeds/“genetics”.
But I DO prefer the way I have started training with the Sage Scout and Nuggets. And that’s my way going forward. Kind of letting the plants tell me how they need to be trained. Versus trying to max out tops and forcing some type of perfect canopy. So you may be onto something there.
