Any ideas. A total newbie here

Hi

My plants have been in the flowering stage for about 7 weeks now but now i am noticeing browning/dying leaves (burning) on some of the buds and only on a couple of plants. I was told these were rockstar clones. Any ideas what i am doing wrong? And how to correct?
I am uploading two pics a good bud and browning bud


Thank you in advance

A slightly overfed plant that is growing too close to the lights?

Thank you. How can i save them? As for the lights, lights are 4 feet above

What are your canopy temps? The leaf tips curling upward is usually a pretty clear indicator of too much heat. So if lights are 4 feet away you need to focus on getting better air exchange so you can get your temps down.

Its a 8 foot high room and i have thermometer hanging at 5 foot mark and the temp at that point is 27 c.

That's a touch hot but probably not hot enough to cause the damage in photos, unless your rh is super low. Sorry, not sure I can help.

Thanks Bugeye. I appreciate all the help you have given me so far. So if it is over fed i should water with just water for bit? And also what do you mean RH being low. What is rh?

What is rh?

Relative Humidity

Ok. Thank you. I am running about 45%

Its light burn.

Wouldnt that be on all plants and buds then? Its only on a few buds and the light is about 4 feet above the plant

It's not impossible for one set of genetics within the same strain to react differently than the others. It does look like something to do with either heat or light intensity. I say that because it appears the lower part of that plant's healthy. Maybe a small clip fan pointing right at the cola would help if it is heat related?

Ok. Thanks. Ill give that a try.
