I did but I put it down to overwatering, @RustyStarbuck72 mentioned this to me about the light change over and the heatwave at thd minute,

I didn't water until after it started, but that was my first thought as well. All I have is that app on my phone for ppfd so I'm sure it's my fault and I don't have it dialed in properly

Haha I downloaded one too but i read they are useless,
It was saying it was brighter than it should of been, I tried to match height and ppfd to the chart and it was way off,
so I'm going by the ppfd chart for the light now instead, then dropping 10% to be sure
That the one I download lol

The chart I'm using tho is 5x5 and I'm growing in 4x4 so have to take a foot off.
But Everythings goin good now after letting them dry out and re watering, do I don't know what to think lol

OK so just to clear it up because I have the same one when it says say 900 ppfd it's really lower? I'm at 70% right now and 20" from the canopy

Go by the lights chart. The app said par was higher

I know what's going to happen, I'm going to lose it and just buy a par meter lol

I just use the tent buddy app to get a rough idea at each stage.. Its not super accurate but helps get a ball park dial in.

Looks like this mate
Remember to change the light type to match yours if you do use it mate..
Shane at migro did a test of free apps on his YouTube. Can't remember what he said about this one but it's helped me I think

Migro on YouTube has a calculation that you plug into that app & actually makes it pretty damn accurate. I forget exactly but you multiply by .93x or something along those lines. He did a side by side with an apogee par meter & results were very similar
