If you don’t have a growlog please answer these questions.
What strain are you growing? Is it Auto, Fem or Reg?
Are you growing Indoor or outdoor?
Are you using nutrients? Which ones? How much?
When the leaves point straight up it means they are not getting sufficient light and will stretch upwards until they get enough light making them tall lanky plants, lower the light 6 inches and wait about an hour if you see a positive difference (leaves stop reaching up) your good if you see the leaves start to droop raise it up a couple inches. repeat until the leaves look somewhat flat but perky and you found the sweet spot

Light has been at this very low height for 1 hour and hasn’t seemed to go back to normal?,could it possibly be something else?
Probably not enough intensity. How many watts?
It’s 1000w?
you may need to adjust the light and add in a whiter light. if you have a decent smart phone you can get a light meter and measure where your light is on the spectrum. purple lights tend to be better for flowering in my opinion. i use both HPS and LED light for my flower stage and mainly MH for veg. whiter light for veg. yellow light for flower
You should not be able to get the light any closer than 12-18". Something isn’t right. What brand light is it?
Aha thank you ,still in vegetation stage day 26 from sprout
I’m not 100% sure on the brand but will find out and get back to you mate
If your Lux rating is 335 that is about 7 Par, which needs to be around 900 or 39,000 lux.
The light has been fine up till yesterday what happened?
Here is a pic out of the manual of my Kingled 1500. What this is showing is the PAR or PPFD rating at different heights. At 18" high the PAR rating is 933 and at 6" the rating is 2245. Naturally, at 6" the light would be way too close for a seedling and the manual suggest 36" at first, and then gradually decreasing the distance over a week’s period so the seedling can adjust to the intensity of the light. An adult plant would be able to handle the 2245 given there was enough Co2 in the environment. At normal atmospheric levels, you could make full use of 900 PAR.
I took the 335 LUX rating from your post (assuming that was the output of the light) and used a light converter on the internet to determine the PAR, which turned out to be 7. If that is correct, then your light is insufficient to grow anything.
Therefore, pull out the manual that came with the light and see if there is a similar graph or chart that came with it to determine what the PAR ratings are at different distances. Also, keep in mind that these LED, as well as HPS and MH) lights decrease in their lifespans and loose intensity. So, if you have been using that light for awhile or if it was originally designed at that low output, then it will not grow your plant.

Moreover, you need to understand spectrum and nanometers. Per the charts below you will see a range of light colors that correspond with a range of nanometers. From my manual you will see the difference between Veg, bloom, and full spectrum. When your plant is growing you need to be in the veg (blue) spectrum of light, although I think full spectrum is better at all times. Nevertheless, you need to be at least in the blue spectrum right now between 400-500 nanometers and at least 450 Par. (i.e. see second pic). When it comes time to flower, you need to switch to the bloom (red) spectrum between 620-780 nanometers.
If your light is under 400 nanometers, it will not grow your plant. If the PAR rating is too weak, it will not grow your plant.
