Brown leaf edges and tips

I have a couple Skunk Heros(Fem) from Ethos that vegged 35 days and now have been on 12/12 for almost 4 Weeks. So around 67 days from seed. I planted them in a Growbox in soil with their nutrient pack. Not sure if this is from too little or too much of something along the edges of the leaves. Also the tips are showing maybe some nutrient and light burn. They are under a Hlg 600R. Only used 24 hour old water from tap whole time. Any help appreciated.

Way too much nitrogen....

light burn would be the top leaves.

How long ago was the nute pack added?

Oh and its a sip,growbox.Was the pack added to the dirt or the water?

Directions have u put it on top of soil when you plant them so about 55 60 days ago. The nutes come in a log type roll.
