Thank you. That's embarrassing. I actually ordered the fixture with "mixed bulbs" (2x 3000K and 2 x 6500K) but it showed up with 4 x 3000's. My mistake was thinking those were the veg bulbs.

I picked up some 6500K bulbs today and switched them over, now running 2 x 3000K's and 2 x 6500K's. Could that have been causing the curving of the leaves? And the yellowing/browning of the leaves?

Should I keep the dome on or off? Someone else suggested moving the light to 4" above the plants, is that ok at this early stage? Should I run 4 bulbs or 2 for now?

Thanks again for any advice.
