For flower I start at 50k and increase to at least 65k. 👍

Avoid a big jump if you can, it will seriously stress the plants imo. Increase gradually per day.

It funny when i look at recommendations on my lght distance with the gavita 6/750 is 2 1/2 ft and im under that atm and only at 46k lux the lower i bring it down the less coverage i get...2 1/2 ft was roughly between 20-30k lux..
I run 2 SF-2000 side by side in a 3x3 pushed apart slightly,, and have an pretty even 60-65k across the whole canopy at 18". I got a PAR meter and that translates to 900+ umol 👍

Depends on your set up. Are you growing hydro- soil- coco- organic? How old are the plants? what strain? To many varibles to get an accurate answer from the internet. Only you can dial it in.

your seedlings will tell u, you want there leaves reaching for the light not shying away from it, i have a 600w led and with seedlings i back it off to 32 inc above seedlings, once they turn into plants i lower it to 26 inc above canopy, see pic Skywalker at 41 days from sprouts.
