My plant is not growing anymore. The new growth has been at this stage for about a week now.
It's feminized seaweed with 1000 watt hps at 30cm away in an organic mix or coco and peat moss.
Humidity 50% and I feed at 6PH but soil test at 7ph.
What am I doing wrong to cause a stunted growth?

Looks like you're burning the plants with too much heat, try moving your light up. It'll take a bit to see nice healthy growth again

I have had rapid growth with the light at the same distance. How far should I position the light away from the canopy?

I'm using an app to measure the LUX. How may lux is safe for my plants?

My plants have looked identical to this before and it was VPD issues every time. Specifically my humidity was way too high. Lowering my humidity and raising my heat slightly fixed the issue really quickly. 22 C is 71 F, which is way too low. I’m almost certain thats your issue. My plants grow best at 80-82 degrees and 45% humidity. Raise your temp up and I bet they bounce back within 24 hours.

That is light burn....VPD.???..look at the tips of the leaf's near the top of the plant...that tells you everything you need to do...
100% light burn.....period

I mean don't listen to ANYBODY....except your plants...Look at what they are telling you....Burned tips only at the top of the plant is light burn......Is it 1000w actual draw or on the package? Remember old leaves don't Heal....Also I just read what you said....Umm how often are you watering....If the roots aren't healthy the plant will show light stress also....
How often are you watering? You are in coco? I've never grown in that...you either need to water more, or water less...Do the exact opposite of what you are doing...Cut off the most obviously damaged leaves and observed any new growth...as your plant gets better gradually bring the light closer...

Light is too close and you may be overwatering

My suggestion was very simple to try and no risk to your plants. Try it and see if it helps. If not, sorry. Not sure why I got flamed for suggesting this.

I missed that.
Like iamrt, I strongly suggest 28 degrees air temp, lower temps slow metabolism. LED doesn't raise leaf temp above air temp with IR like HPS etc.

This! Exactly what I meant when I said VPD. Try and see what happens!

wtf?
so 2 questions:

30 cm or 30 inch

As matter of fact it's not 1000k as I thought. Real wattage is barely 265 watt. Note that I see the lower branches reaching up and growing whereas the tips are still there a week before my initial post here
