This stretch I believed happen during 75% which would be a 3-4” stretch from 1000 ppfd to 1200 ppfd. If on 50% that would be 600-700 ppfd. I don’t think I had it on 50% during this stretch but I’m not positive. I may need to put a camera on it or measure it from now on with pictures

but I’m not seeing the deficiency you speak of

pic 2. the plant that is in the upper left hand corner.

and the leaf margins:
This looks like the result of excessive heat, root problems (possibly from overwatering) and/or suffering from extreme humidity levels (such as very high or low humidity).
When the serrated edges of marijuana leaves curls or tipped up like that, it’s often a sign of temperature stress, overwatering/root problems or extreme humidity levels. This plant was overwatered and living in high heat, which is what caused these symptoms.

Are you talking about the clone in the background that is bright yellow with nitrogen, phosphorus etc deficiency that got under fed? This plant I showed you is green. It does have tip burn and maybe some upturn. The soil is hot on these jack herer so they typically get tip burn. I don’t think much about it.

hard to tell if it was a clone or not.

That's fair.
OP how are you getting those numbers?

the red blurple tests super high in ppfd. infrared does too i think. i heard you can't trust it...i didn't get very big buds with red blurple until i got some super big diodes from the AWI spotlights.

Blue blurple is great for early veg imo. it gives me super dense and short plants.
