Help please... possible Light burn?

[Kumu7272]

Looking for some advice as to whether this is possible light burn. Only started appearing a few weeks ago and it's getting worse. It's a 1k watt light which is making.me think I've maybe grew to tall.
They are fed with tomato food for nutrients, the smaller plants seem to be doing fine. Nothing much has changed apart from size of plant. Will they still flower okay?

Many thanks guys!

Soil is to hot. Water only for 2 weeks Back off on the nitrogen buy about 1/2. Time to flip. Pull all those tall branches down even with the canopy. Clean everything up 3/4 up the stalks and think about switching to flower. She will fill the tent up when you flip her. Real nice job so far!

I don’t think that is a true 1k watt light.

It may be a potassium deficiency.

Thanks for the tips!

Thank you!! This is very helpful. I think you helped me on my other post to! I ended up getting a bigger tent and this is my first real attempt.
I will back off with the nutrients as suggested, and try to trim some of the bottom leaves.
Definitely flower time soon!

Yeah I was sceptical about 1k, it certainly bests my old 100w piece of trash though! :D

I just took a little closer look.

After a little closer look you may be on track with light burn, I'm doing 3 things at once here. If your light can be dimmed maybe turn it back to about 75%. Everything else I said. I'd still fallow threw on.

There's no way that's light burn. If your light was 18" lower MAYBE. I doubt those plants are even seeing 550 PPFD.

Is this issue showing in lower growth too?

That’s not 1000watt this is

California light works 1000

No, only in the top region

Thanks for the responses everyone.

I have reduced the nutrients, and flipped to flowering. Hopefully the symptoms will reduce, I will post updates in the near future :)

I agree with the soil being too hot or nutes being too strong

Update:

Stopped the nutrients, entered flowering.
On week 3, I am happy with the progress. Thankyou to everyone who posted advice, it was extremely helpful! :D
