Based on the data above, the light is pulling 153 watts and the PPFD map is based on 60 centimeters square or 2 feet square, with the light at 16 inches above the canopy. You say you hung the light 12" above the canopy.

You have a tent that is 60 inches x 60 inches, or 5'x5', far larger than the 2'x2' footprint of the light. Hanging this light at 16" above the canopy means almost zero light will reach the rest of the tent. Hanging the light 36" above the canopy and the light intensity goes way, way down. Hanging the light at 12" as you did means even less light footprint for the rest of the tent.

The light is far too weak for the tent you have, and you can tell by the fact that the light is only 153 watts. To successfully flower a 5'x5' tent you need at least an HLG-600 or better, a quantum LED light pulling 600 watts.

I believe it's 60cm. Not inches.

Well the light distance would explain why the upper fan leaves are pretty much burnt to a crisp and disintegrated. You're pretty close to harvest. You have lower flowers unaffected by the lights. If you really need to know cut one down and let it dry. Don't stick it in the microwave, just let it dry on it's own. I'm going to guess it's going to be the same result you already had.

Raises the question, what were the lowers like on the original plant? If they were just like the upper buds, it's likely a problem with the seeds. If it were too much light intensity the lowers wouldn't be affected as the intensity would be lower.

How do you dry them?

I believe I posted in your thread telling you that "sampling" or "not having patience" as I call it will ruin the experience....

Have you tried Critical Jack, Gorilla, OG Kush or Remo Chemo? I found all of those to be very strong, grew well and came out like they described and pictured.

I've grown their Ocean Grown Cookies, and also Deep Sweet Grapefruit. Both were meh.

Thank you all for the help, i now understand that +1200 ppfd probably didint ruin the potency, but it leaves me with another mistery , what did it ? i mean could they have been mistaken in 2 packages and sent me cbd ? or grow error ? for example using half the recommend dose of nutrients could cause this , plants did show def. for using only half , but buds are big and rock solid and smell oh so great... but potency 0

DinaFem, before they got busted, used to out-source their seedgrows to 3rd-party illegal growers, so the possibility is there that something went astray....

I doubt that LED competes with the sun. So no. If you are getting "burn" it appears as bleaching. You will see buds turning literally white where they are getting too much light. Easy thing to solve, bend the bud over or even supercrop by snapping the branch in a controlled manor so it has to grow sideways. Or just have a couple buds that are bleached and don't worry about it. lol

That's why I asked about lot numbers. If they made a mistake with a seed run and mislabelled it that's one thing, but two?
Too bad there's no way for you to be sure they're not from the same run. What did they say when you contacted them?
