Leaves browning on the top - help

I started four (well six but two were boys) plants at the same time from seed. Three seem like they are still growing probably not ready for a week or two but this one has yellow leaves all over and the leaves on top are browning. I'm afraid it is done or something is wrong? but I am unsure.

I have a grow journal here: https://www.rollitup.org/grow-journals/661298-jock-horror-indoor-600w-hid-2.html

But I really want an answer tonight just on this one question here if possible. I'll post pics of the brown tops.

More photos - using two different light functions on my phone. The greener one is closer to what it looks like. I've decided I'm going to chop them tomorrow night. I moved this plant to a room where it will be dark. Still concerned about it. Doesn't seem healthy.

top of that bud looks dead.
also do some laundry dude.

If I harvest the plant does that mean the quality is crap on that section? How does the top die?

I have four kids and a pregnant wife laundry is always getting done in this house.

Looks like some major heat stress, just did the same to 2 of mine by not paying attention.

Both plants are now going into the hash making bin.

Yeah could be heat stress, definitely something bad wrong with it. That's a shame because those are some massive colas, what strain? What are your temps and rh as well? More info will help, hopefully you can save them. Or make a ton of hash.

I was gonna say heat stress/light stress. That's the way it seems, anyways.

Any bud rot inside where the leaves attach to the stalk?

I think it was too close to the lights. I didn't think it was that hot but it has been hot the past few days and this was the tallest plant closest to the light. I harvested just this one and it was 68g. I'll post photos tomorrow
