Yep, That's a lot of light for your space this early on, although your leaves are reaching so they don't look to be under light stress from what I can see.
One thing you might want to consider is adding a light mover! Set up correctly, you'll be able to run your fixture at 12" above the canopy and develop buds 2' long. You'll not be subject to limitations of the led hotspot.
I find with my Kind 750 that when watts match ppm, I get good results. At 500watts, feeding at 500ppm works
Good luck bro. You're off to a nice start.
