How is she looking? Never done harvest in my life and is going to be very close to it, i need some advice!!

honestly - no feed at all, unless you have pk booster, then in two weeks you will need it for few feeds. her leaf structure tells me that she was overfed heavily. curling leaves tells me that ph was wrong her overall look, gives a hunch that you watered her wrong too, lift pots, you will feel naturally, when it is light, for such girl i think you need 400-600ml x 3 times every10-15 min every 4-5 days, not more, that way you'll soak roots well during watering and will give time for them to get oxygen while soil is getting dryer. 4-5 weeks till harvest i would guess. All the best !
