Ok well you should take the toasted leaves off but you should decide if you want any of that energy to be spent in upward growth since the plant will replace it while in veg. To mange that energy you can super crop if you have multiple tops already because going to far with topping has yet to pay off for me. Or otherwise you can top at the same time but in either case do not remove 20% "1/5th" of the total leaf mass. If you have topped the plant in that case I encourage super cropping to manage the plant. Basically you pinch the stem of a dominant shoot to allow the other 3 to fatten up, or you pinch and bend a dominant shoot if it's out of control. Or maybe you pinch/bend over all the tops so the rest of the plants shoots can catch up a little bit.
Indoor lighting is hot it's all focused light hotter than infrared light. We can push plants to 80F with 50% humidity with the lights optimally close but if your environmental conditions become other than optimal the light is too intense. If you can't nail down environment keep the light further away.
