Seedlings... Is this nute burn?

Got 3 Big Devil Auto's going right now in with the rest of my plants. They're in solo cups, rockwool has a wick hanging through growstones into nutrient solution. I have the solution at about 500ppm, seedlings germinated on 11/15, and transplanted to solo cup on 11/28.




It looks like nute burn to me, just want to make sure as I've never grown Autos before, don't know if they're more sensitive to certain things than most plants.



Here's a picture of my entire setup, have the seedlings cups sitting on the 3gal DWC buckets so they werent sitting well below the canopy.

too much nutes and looks also like ph issue showing a mag def. what is ph?

Indoor autoflower? Why? How many hours of light do they get?

18/6 right now, until the other photos theyre in with go into flower. That will be 40 days into their 53 day finishing time. So I think that should be enough. Buddy of mine gave me three fem Big Devil seeds so I popped them.

pH is 5.6

I've never grown hydro but in soil for veg your ph should be closer to 6.5 and then 5.8 for flower. Reason being certain nutrients are absorbed at different rates at different ph levels Check this out:
