Same strain, nutes, medium, different results?

Hey guys,
Just starting these Purple Haze and can't seem to figure out why I have one that is doing great and one that looks like its not so happy. Using GH 3 part nutes, 2.5 mg each in 1.5 gallons of distilled water with CalMag and H-guard. Any ideas why one would look like this and not the other? Everything is identical.
Any ideas appreciated.
Thanks!

If they’re from seed it’s probably genetic differences or there could have been a hot spot in the soil

Thanks for the reply, t hat was the only think I could think of too. Its DWC so it must have been a goofy seed.
