Purple/Pink lining on fan leaves?

Does anybody know what could be causing these dark purple/pink edges on my fan leaves?

post a picture of the whole plant please
in natural light
they look very pale and tired

@kingromano here's some more pictures

yeah its a stressed plant .. purple stems and all
how far is your light from the plants
and what is the wattage
i think they are shocked by the lumens

It's 20 inches away. 600W Vivosun LED. I had that same though, so I tried to move it as high up as possible, but 20 inches is the furthest I can get it.

yeah i dont know led .. but they must be even more brighter than 600 hps .. so its way too close
you need to reduce the daily light integral ..

young vegging plant require few light

A 600w vivosun led isnt anywhere near the same light output as a 600w hps. Too much light is not your issue. Likely hot soil like a lot of new soil growers.

Post some details of your soil and additives feeding/watering habits.
