Got a sec? Need some advice…

First sign of rot, is time to chop! If you spend time with your plants and know what to look for, you really dont lose much if any. But window is quite small, and if not a plant youve grow many times in past can be hard to judge. But 80 to 85 days is getting close imo only, because of environmental factors, they will determine how long you can flower.

Those are estimates because most people don’t have par meters. Maybe since you seem to be such an authority, you can explain to me how it hurts my plants if par is less than 1000 across the canopy and heat is not an issue?
On another note, these forums are full of people with a variety of knowledge and experience, usually here to help one another, not to be a smart ass. You could use a little work on your delivery.

If heat isn't an issue than light obviously is. The serrated edges of your leaves are curling up.

Manufacturers test and measure their lights at specific heights. They aren't estimates. If you hang your light at the height the manufacturer recommends then your PPFD values should be exactly +- what they advertise. You don't need a meter unless you are trying to adjust heights based on less than 100% settings.

I don’t disagree with anything you said. My light is advertised at 320 watts but actually draws closer to 350 for some reason. Manufacturer says that falls within tolerances so they’re OK with it. So then I use my meter for fine-tuning but having said that, the visual indicators that you mention are apparent so I raised my light as mentioned previously.
Thanks for taking the time to comment.

The leaves are getting faded and starting to taco. You have a long way until harvest. Trust your electronics or trust a bunch of growers. It's up to you.
