Just the tip!

Everything is going swimmingly except the very tips of my leaves. Any ideas? Humboldt Hella Jelly, PPFD 460, Living Soil ”light” and amendments, 3 weeks into veg, 4 1/2 weeks from sprout.

Mine looked like that from week 4. As long as it is not accompanied by curling or leaf necrosis it is associated with max nutrition uptake. Also looks like early light burn but with no other symptoms or presentations I would hold steady.
Pretty plants.

Thanks! Yeah, the plants are healthy. They are actually doing it less now(with higher ppfd) and it mostly resolves as they get older. Lil girl must be nute sensitive.

I have finally figured out what causes yellow tips like that!!! Took me ages.

It’s a warning sign of too much K (potassium)

Just the tip!
