m0useanswered grow question a month ago I would lower that DLI.
Research has suggested the upper limits without CO2 added into the grow is 40. This was done by Dr.Brucebugbee, you can look him up on youtube, a nice wealth of information.
I run my tent around 35-37 DLI, its not set in stone. some plants can handle more others not as much.
Your VPD seems on point, or just on the edge of high. Need to know RH though to fully figure it out.
