I think it is a secondary leaf spur, not a male pre-flower. Keep an eye on fert levels still. A dose of sea tea will help the stress from the high ferts. The small yellow blemishes on the leaf fringes are indicators or prior fert overload. That's part or the reason your plant is shaped like an umbrella (curled down), rather than like a challis. If you maintain high fert levels at this stage, you run the risk of a diminished harvest. Good luck.
I would not be lst'n during sexing honestly. But people swear you gotta really stress them to herm on you. Looks like she has been working on lower leaf sets rather then flowering because of the bend.
