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.
