How much longer?

Sativa leaning hybrid now on day 87 since flipping to 12/12. Plant is in a 3 gallon pot with likely 2.5 gallons of soil so is likely very rootbound. She is currently under a spiderfarm1000 led panel, before she was under the led and 315 CMH 3100k . Humidity is low 50's and the temps are the mid 70's. Suggestions on what i'm looking for to suggest she's ready to harvest or guidance on steps I might take to help her limp to the finishline

Thanks again to the RIU tribe for the help and guidance on my first indoor grow!
