Your DLI is maxed out for sure, maybe a little high, without CO2 the max is 40-45. But some varieties do fine with that. Watch for foxtailing. Brown tips are not something to worry about, almost everyone gets these at one time or another, just a little heavy on the nutrients somewhere along the line. Just watch that it doesn’t damage more of the leaf. You’re pushing the limits I’d say. Just make sure the buds stay nice and tight. Every plant can surprise you.

It looks like the brown spots are more likely due to over-fertilization rather than light. Have you measured your runoff yet, and what are the EC and pH values? This can help you determine if there are too many salts in the soil. To better adjust the light, I recommend an app called Photone, where you can measure the light intensity with your phone or tablet. It's not 100% accurate, but it definitely helps.

Tip burns from long term over feeding, not tip burn from too much light.
