I've noticed with some plants late in flowering (around 40-45 days) the plant wants lowered ppm levels from like 1000 to 750. I know this bc the ph will crash to 5.0, and once I lower the ppm's to 750 range the ph will stay steady in the 6.0 range. My question is, when this happens is the plant telling you its done flowering or close to it?? Or should I just keep the ppm low around 750 and keep it on schedule to chop in the 60-65 day range??
DWC is plant done based on wanting lower levels of PPM

A lot of things are going to effect when it's time to harvest. It took four whole months to grow and harvest Super Silver Haze (pics in signature). That was the longest strain I ever grew. Other things that can determine when to harvest are the growing conditions, health of the plants, how long they vegged, and a few other things.
Like he said, get a jeweler's loupe. I like my 30x for quickly looking for bugs and triches, and a 100x for looking closely at the triches. I like to harvest when they are half milky, and half amber. Some people harvest when they see the first amber triches, but I don't think anyone purposely harvests past half amber. More than half, and your weed starts becoming couch-lock weed, and not in a fun way. It'll just make you want to take a nap.
You can get loupes and handheld microscopes for cheap on Amazon.

I've found just from personal experience that my babies do prefer a very slight drop in ppms when it comes closer to the end of it's life cycle (exluding flush, that is). Why this is or if it is even the same mechanism that is making your plants want less, I have no clue. But this is far from an effective way to determine readiness. As Rkymtnman suggested, gotta get a scope or at least one of those magnifying loupes!
Yeah you're comment is what I was asking.. I really don't even use a microscope anymore. Its always between 58-67 days usually closer to 62.

What type of system are you running?
DWC, my mature plants in flower usually max out at 1100 ppm

How are the roots? I’ve had a couple that had PH crash after a few days near the end and the middle of the root ball was starting to get messed up a bit. Just a thought.
