6.0 ph , 73 degrees and 58% humidity , vispectra p2000 18 inches from canopy at 75% dimming settingsThere are multiple things that could cause that, so it's best to go through everything so as to pinpoint the likely issue and resolve it as fast as possible rather than just tell you to turn down your light. Fill in the gaps, if you will:
What are you growing in (DWC, RDWC, coco, etc) feed and watering habits?
pH?
EC?
Temp and humidity of canopy?
PPFD of canopy (or if you don't know that, the brand and model of light and hanging height and dimmed setting)?
Build a soil 3.0, no added nutes yet, it’s supposed to be a water only living soilWhat is your medium and feeding schedule?
So maybe give em a lil less water too much can do thatPicture from about 2 hours ago, now leaves don’t look droopy
Actually started looking better the following morningI think this is one of those rare times it actually is the light. That light at 75% and only 18inches away is a bit overkill for that small of a plant I'd say. Just turn it down to 50% and keep an eye on it.
Cal Mag... that easyDoes this look ok
