Why is this happening? Brown crispy leaves!

[Green3726]

Hi! I am wondering if anyone is able to give me some advice in why the top leaves are turning brown and crispy and shriveled and what I can do to fix it! It seems to be only the top, i am using LED lights and it could be from the light but when I look online nutrient burn comes up a lot but I haven’t added any additional nutrients besides what came in the soil (fox farms ocean forest soil). ANY SUGGESTIONS?

Also I transitioned my plant to flowering a few weeks ago. Is there anything I should be doing? Or just let it be?

Check you run off ph, also, it’s too hot I suspect, the majority of the damage is on the higher parts of the plants closest to the light. I’d raise the light, or turn it down and increase airflow.
