Can't get an exact date, but i would estimate about 3 weeks to go based on photos for mainly cloudy with some ambers, but it may happen faster, so ask again in a week or 2.
Since u're in coco just keep the nutes at the current dose untill you know you only got 1 week to go and stop giving nutes by that point, stick to water only from that point on.
Try to find a way to stabilize the camera and get focus on the bud to take a really close up photo and check if the cristals appear more detailed than in the picture in the growdiary, its hard because buds are really complex for a phone's camera but keeping the proper distance with the right zoom can do wonders, altho a macro shot would help out a lot more.
You can let them get a lil bit more thristy next time at around week 7, just not dead, but a bit thirsty and it will help the plant produce more cannabinoids, terpenes and oils, and can get you an increase of thc of up to 50%. You can still do it but it would basically be like a trial, so if you do it do in just one and keep the others as a controll group, then check wich is the most potent and more intense version. You can also supplement with uv-B on further grows and it will also increase ur thc, just gotta take it slow or you risk burning the plant and the thc.
