First time photo , Fat Banana

No reason why it would hermie unless the mother plant also one the cutting in pic 1 is showing signs of tip burn and dark green leaves could be a nitrogen excess causing lock out to other nutrients . Just give plain ph'd water for now

Hi mate Dont stop feeds until 1 week before harvest then just give plain water for that last week DONT Overwater them

If you’re wanting no amber and just mostly milky then yeah you seem pretty much on track. She’s got a lot of white pistils still, all sticking out. For me, I’d wait another 2 weeks(just my opinion). I think she’s still gonna fatten up some in that time. If you could look at her trichomes, that would be the best way to know exactly. Good luck
