Hey dude, If you are referring to the plant in pictures 11-17 then she is suffering a P deficinecy seen it before fixed it by increasing PH to 6.5> and adding more bloom nutrients and/or a bloom booster. Looking at the size of her she could probably take more than what you are currently feeding... good luck, let me know how you get on✌️🏻

So there are a few things that could cause this but most commonly it is due to light leaks or an excessive amount of nitrogen. Cut back on any grow nutrients and focus more so on nutrients meant for bloom. Also you could adjust the light schedule temporarily to a 13-14 hours of darkness. Double check the flowering areas as well on the off chance you may have a male plant which produces small pollen sacs. Good luck on the grow.

Hi there! Indeed this is weird... I'm assuming your nutrients informations for week 9 are wrong? Such heavy doses would certainly create a nutrients burn + lockout for weeks. Since your plants look healthy, let's dig into other possibilities. I'm also assuming you already made sure this was not a male, and I don't see bananas on the pictures. Do you move/switch the pots inside your grow room? Was this plant at the same place for the last weeks? If so, she may suffer from not having enough light, resulting in late flowering compared to her sisters. What spectrum is the lamp currently diffusing onto this girl? Keep us up-to-date and happy growing

I’d continue to wait if it was me. You could also try 10/14 for a few days to see if that gets her started. Good luck!

Light leaks and/or too much Nitrogen can make a plant not to go into flowering stage; and talking about nitrogen, if you are really feeding 90 ml/lt worth of nutes, then it's no wonder you are having trouble and it's a miracle they haven't been burnt to a crisp. Flush the hell out of that plant, if not all of them and get an EC/PPM meter ASAP.
