That's not anything major... maybe knock 1/2 to 1 hour off your light cycle. maybe it is still a reperussion of the 360w applied. so, give it time to react... small issue so you can be patient.
depending on efficacy, you may only need 25w/sq ft to provide roughly maximum DLI relative to ambient co2 and mostly uncontroled environmental variables. if your light has accuract specifications, can google how to calculate DLI / ppfd etc (daily light integral) to havea good guesstimate if you are near that ceiliing... this isn't mean to be super precise, but it will be accurate... a good ballpark concept to apply with confidence.
if it's drooping more severely, maybe kick it down to a 16/8 cycle for 3-7 days... then, slowly increase the light schedule. if there's any lingering effect from the 360w applied, that would go a long way to mitigating it.

*** need an edit in this sentence
depending on efficacy, you may only need 25w/sq over 18 hours ft to provide roughly maximum DLI relative to ambient c
photons/s is measured in umol/s.... so hours of use will be directly 1:1 proportional to affecting DLI. add 25% more time, ceteris paribus, adds 25% DLI. you'll see that in any properly pregenerated DLI table. the plant can quite literally only handle X photons per day relative to various environmental variables. force feeding will be obvious when you see negative symptoms like wilting for long periods of time at end of day or even light buns on leaves, but the latter are not required.

Leafs often go down a bit while in ''sleeping'' mode(lights off)...
To me this is perfectly normal :)
And 15 hours of light for autoflowers is oke, not that much but oke. They can even do 18-20 hours.
I know people that do 24hours(risky).
Your plants will be fine :)
Goodluck

3 days in, only cotydelons with no sign of the first true leaves. Have you seen this and has it recovered?This plant was stunted at the start after he couldn't get his hat off, but now looks pretty healthy however it's been 3 days of just cotydelons and absolutely no sign of the first true leaves. Have you had this before and did it recover to eventually grow true leaves?

First Grow 4 weeks into Veg - Let my humidity get too high for 1 night. Need help with mold/septoria/?Last 3 days I've pruned diseased leaves every morning, foliar sprayed peroxide leaves & topsoil, & added some to watering solution. Is only affecting one plant in tent. Humidity no longer issue (was waiting 4 inline fan). If I keep pulling off leaves it's going to die anyway.

Big difference in first true leaves' sizeBig difference in first true leaves' size
Its almost day 5 after emergence. Is this normal? Should I be concerned?
ALSO: It's still a seedling but, I maybe think the cup in which i'm growing it in is too small, or rather I put too little soil (9cm diameter , 4cm tall dirt).

I'm seeing some holes/yellow spots on a couple leaves of this plant. It also seems to be growing slower and more Dense than my other plants. Is this cause for concern or is this plant just a little slower to grow? I'm thinking its just inconsistent genetics.

Crispy leaves?Crispy leaves developing as it flowers. Seems to just be those that had some spots from what appeared to be a magnesium deficiency. I hit it with cal-mag and the spots stopped but recently the most affected leaves are shrivelled. Only maybe 4-6 leaves right now.

Hi guys, please help! Everything was fine with my plants, they are flowering for 4 weeks. But when I opened the box today, I found that one of them is not doing well. All the leaves are dropped down, and one branch dropped to the ground and almost broke.
What could it be?
