Dli of 90 too high ?

[tronN00dles]

Just to throw in some context... PPFD represents a measurement of light intensity over a given area per second; DLI represents a measurement of light intensity per day.

40-45 DLI is a daily light intensity you can expect on average annually in Southern California or Australia. A DLI of 60 is comparable to what you may see in Southern California in July.

A DLI of is around 90 is what I'd expect in the infernos of Hell

I use Photone as well. I've had good success with the DLI schedules they provide on their website for both photos and autos. I would double check your app settings (LED white vs LED R/B, etc.) , or perhaps try to take an average measurement across the whole canopy?

That’s under 68 dli I’m using an Photone iPhone app with iPhone diffuser…it works accurate …and in my tent on my 12/12s my ppfd or whatever was 1300…and they’ve haven’t been curling or anything perfectly Healty… Starting to think dli overrated

DLI is not overrated my friend, its just one integral part of the big picture.
This whole growing thing is one big balancing act between nutrition and environment.
You think you got your light set perfect, then leaves start to look fried or heat stressed. Are temps in the tent too high, or do you have a nutrient deficiency thats making your plants overly light sensitive, or is your humidity out of the proper range? There is always one more hurdle to jump.
Your plants look good, and I do mean GOOD! So your obviously doing it right.
