Very slow flowering growth , need help

I have (from what i can assume is , ) a black cherry soda plant that i grew from a seed in an eighth i got from my local dispensary. I vegged it for 2 and a half months under 5 cfls white pistol preflowers were present already when i flipped to flowering February 30th under 7 2700k cfls and 1 6500k cfl , so its at about 6 weeks being the 18th today . She was a damn rocket through veg and flowering started vigourously then seemed to halt , i feed 8 ml floranova bloom into soil, along with 2ml mammoth P , 15-30 ml sugaree , always ph measure , usually about once a week , i have taken a step already as i flushed her with 14 gallons of ro water and i moved her outside just yesterday because where i live is perfect temps right now and light hours are same as her schedule , flushed because i read up about salt buildup causing nute lockout and halting growth . Any advice or of i just need to be more patient let me know, thanks a lot

 

Appreciated, i assumed and ill let her finish under the sun i think . Thanks a lot amigos

 

First plant ive ever grown only seed ive ever tried to sprout so happy with the fact it was even female . Do you know if its alright to take a clone this late in flower??, or should i do a gentle harvest , reveg and take a clone from that?
