How to tell from light burn vs nute burn?

Some of the tips of my leaves are turning yellow/white. This is only on the top leaves. I would guess this is from light burning the leaves and not nute burn since all of the lower leaves are not showing anything like it.

Are ur leaves thick? They look so. Its neither from what I'm seem its overwatering. Or roots finding it hard to breathe from the bottom.. With the dose ur giving. Nute burn is unlikely. I don't see it. But I often see tat when roots are struggling to breathe. Either from heavy substrate, (tightly packaged) or u need to let the top soil dry in more as when it does air is drawn into ur sub and therefore helping ur roots breathe. Nute burn id see more crispy tips.

I went bk to ur 2nd wk..ur leaves look thick. U hv good nute uptake. But feeding too often too much water is been taken up. Leads to thick almost like rubbery feeling leafs Even high feed once a wk and 1-2 good waterings a wk. Only needs feeding 2-3 times a wk nutes&water feeds included Good luck.
