Very possible you are drowning the roots and not allowing them to get proper oxygen. This also creates lockouts and a ton of other problem. Note that the damaged leaves wont recover. Look for the new growth.

Yeah, id back down on the watering but also that's a hot light that's CLOSE to your plants, id have it set a lot higher. like 30 inches plus. I have 2 seedlings in this stage that are thriving on a 1000watt led panel 32" above and they love the thing no stretching. And that 750HPS is a better light then what im doing so you should be fine :)

That was my first guess. Light or nute burn. I don't have experience with HPS so I figured 2ft was decent. But that was an assumption. After looking at the picture again, I noticed the soil looked super wet for such a small plant. That led me to thinking he's drowning them too.

I’d recommend taking the guesswork out of it. A Lux meter (33 buck on Amazon) really comes in handy for determining how much HID light your plants are getting. I think your way too close. I just tested mine under 750 watts and I’d do 30 inches.
