What causes this? Is it light stress or deficiency ?

Is it light stress or something else?

What do you mean? Don't quite understand what you mean? If you can explain better, please :)

What do you think has caused this?

 

[Credits420OG]

So the leaf top of the plant? You Mean?

Yes

 

[Credits420OG]

Ja

Maybe Nutrients burn / maybe to close to the lights.

Can you take a picture of the side of the plant or take a picture of the whole plant?

Is this about the yellow leaf tips? If so, there are several possible causes. It could be a nutrient deficiency or moisture not getting to the end of the leaves (that can appear to be a nutrient deficiency). High temperature and low humidity can cause it. Excess phosphorous can burn leaf tips. Light burn will have other indicators that I'm not seeing, so it seems less likely in this case.

Doesn't look it as copper deficiency more?

Copper deficiency is rare, but possible. This fits the description somewhat. The dark green could also be due to an abundance of nitrogen and the chlorotic leaf tips could be caused by something else. Then again, it may be the phenotype. I think I'd probably stop the nutrients to see if the plant can grow out of it.

It is definitely nutrition burn

Nute Burn yes: Cause - Too heavy on feed - R/H too low. Too much light driving them is doubtfull. Cut back on feed and water if an issue. Check your VPD and destress with a J

I really like reading your replies.

Thanks. There are lots of interesting topics and questions here on the farm, and so much to learn.

Agreed.
