This is the new settings I am trying, previous to this the lights were lower and brighter. I am trying to find the right height for this light and my setup, whilst not trying to burn nor under light them.The ppfd isn’t that high, but that DLI is up there. You getting that with 12/12?
If so either the ppfd or DLI readings are off.
I noticed that PPFD readings differ when the tent is open versus when the tent is closed. I use a phone app so I have to hold the phone when I'm taking a reading. I think my arm and hand also affect the reading. My theory is that reflections matter. So now I keep the tent as close to the normal growing condition as I can. That just means I put my arm through the smallest gap I can.The ppfd isn’t that high, but that DLI is up there. You getting that with 12/12?

An open or closed tent definitely effects the ppfd with all that reflective material in a tent. It’s why it’s there.I noticed that PPFD readings differ when the tent is open versus when the tent is closed. I use a phone app so I have to hold the phone when I'm taking a reading.

I don't use the PPFD readings very often, however. I mostly just go by how well the plants are growing.
What he said ^^^^^Something is still wrong with your PPFD or DLI conversion. Using your claimed 435 PPFD and the HLG calculator I'm coming up with a DLI of 37.81 and have to use 24 hours of light on to get it. Other calculators online are showing 37.58 to 37.90,,,, something is wrong. Either you have a bad PPFD reading or the DLI calculation is setup wrong if your running 12/12.
Yup and sulphur etc.If a plant has a slight Mg deficiency, the burn looks a bit different.
True, but if one cites numbers and they obviously don’t make sense based on the info provided the OP should be informed. We are all here to learn, just trying to be helpful is why I pointed it out.Plants don’t care about numbers… fact.
glad to see they are improving.
Galaxy S10+True, but if one cites numbers and they obviously don’t make sense based on the info provided the OP should be informed. We are all here to learn, just trying to be helpful is why I pointed it out.
Are you really running your light 20 hours like a auto flower?Galaxy S10+
Light is 30inches away at 70%, because they were getting burnt before.
Looks like PPFD Meter app DLI is way off, thanks for the tips and pointing it out.

Why not? Vegetative growth is vegetative growth.Are you really running your light 20 hours like a auto flower?
Then they must be autoflower…. No? How else would they be flowering.If your wanting to develop a good DLI number PPFD needs to be semi accurate and duration of light on time is a data point. Plus those plants are in flower.
What ever your light time on is that needs to be set correctly. Your screen shots are showing light on 20 hours...Plant is on 12/12, they are photo dark angel. On Week 10 ready for chop tomorrow.
Not this plant, but my others.
