Cause for mottling leaves?

hey there Beardy , basically i have to disagree with my growmies on this one. The other plants muscled through the hard part totally fine, but this one has residual root problems. You can see from the curling of the leafs , yellowing tips, and a taco-ing, and you know that leafs are just the reflection of the roots, right? so the roots are in pain. My hypothesis is that there is some compacted medium that has trapped some water in there so there are signs of "overwatering" and basically some kinds of bad bacteria attacking the roots. So you to fix the roots and break down the problem roots. Try to give one or two feedings to this one plant using only diamond nectar at full strength. This should start breaking down the roots correctly and could also fix the medium. Maybe you might need to do this more than 1 day , like 2 or even three days. Just respond to the plant if you see it needs more that's it. basically the fluvic acid will fix it . Hope this helps ! 🚀

That's just genetic not all phenotypes got 100% perfect leaves 100% of time. Nothing to worry about. Happy growing

It looks like Over watering stress too me.

Scoop loop and check leaves. Think you have thrips

Plants are showing you that you have a zinc issue. Cheers!
