Girl Scout cookies from Fast buds
In soil, Gaia Green nutrients
AC Infinity ionboard S24 @ 100% - 32" from canopy
Schedule 18/6
R/O water mixed 50/50 with dechlorinated tap water.
Temps between 75 - 81 F
Humidity 48 - 58
Been lazy and not been checking DLI or PPFD

This pic was taken yesterday.

Here's one from today

This plant started out small and wanted to grow tall and skinny. Did LST pulled it down almost horizontal but then found a different training technique where you cut the top to fan leaves every time they grow out.
Allowing the side branches to catch up to the top giving you a flat canopy. Removed the tie down that was pulling the plant horizontal, allowing it to grow straight up again

This plant showed a few clawed leaves in the beginning with possibly too much nitrogen. Then it seemed to acclimate and it's leaves have been extremely dark green and glossy. But it's grown better than any plant I've had with the largest buds. They are incredibly dense and big.

It's near the end, will be chopping in the next week or two. I noticed the sugar leaves on the top bud yellowing on the sides and there's some small brown spots on a couple. There's one other bud that's lower in the canopy that's showing signs of the same yellowing on the sides of the sugar leaves.

Still fairly new to growing and have not seen this before. Anybody seen this or experienced this before and have an idea of what it is? My worst fear at this point is Bud rot but feels unlikely as I've kept humidity very low with a VPD around 1.3

I moved the light up to about 42" and notched it down to 80% just in case it's light burn.

It looks like too much light, to me.

Thank you. I really think that's it too but wanted to get some second opinions.

Just realized I put it in the wrong category, not sure how to move it

Yep, it flew a little too close to the sun I just turned out turned down your output percentage around 5 to 10%. It’s not gonna make anything worse in terms of yield.

It's OK just keep it going here with the updates. Moving the light up should cure the issue.

Hasn't gotten any worse since I moved the light up and dropped it to 80%, now I just have to decide when it's time to chop it.

Have the hardest time figuring out if the trichomes are right
