It's 21 days old now and going great but some yellowing on the lower fan leaves and tips of new growth. My other 2 plants aren't doing it with all the same ffhf dirt.

I grow mostly in DWC but I would either say .. Mag or Cal Def !! Maybe !!
That's what it looks like to me, but then you never know. try Epson Salt

Looks like the beginnings of a potassium deficiency. Can tell 'cause it starts on the tips, and only half of the leaf margin. Mag would be the entire margin yellowing, and not just at the tips. Cal is spotty.

Are they getting any nutes, or just plain water? Probably about time to start lightly supplementing.

No nutes yet but have Tiger Bloom ready. Maybe 1/4 strength next watering.
