Lights too close to canopy

My lights are around 6-9 inches from the top of my canopy. My plants are starting to look stressed and I'm thinking the light intensity may be too high. I just dimmed the lights down from 100 percent to 40. The lux meter on my phone is now reading 60000 which is as high as it will go so I have no idea how high the intensity was before.

Anyway my concern is, did I lower the intensity too much? I have never finished a grow with the lights so low.

Bend the tops down or supercrop if you're not too far into flower.

Assume you can't raise light....

I had a similar problem, burnt the tips of 3 colas, couldn't raise light anymore.

So I tried monster cropping but the branches just straghtened out to the same spot.

So I tied the branches to some 1" pcv in my tent and tightened the tie downs until the were out of the high heat zone. Works.

I'm not very experienced but I'm thinking about what I'd do if I was in this situation and it's pretty much what you've done. My initial thought was that 40% mightve been too low, but I don't know what light it is and even if I did I still wouldn't know for sure. I measure light intensity with ppfd. I've never used the lux meter. You might could switch to ppfd just to get an idea how much of a change in intensity it is between 100-40.
