Hey team. first time grower here and ive noticed this pop up on my leaves. I grow indoor in soil, Plant is about 4 weeks old . Spots are on about half the leaves im still getting good growth out of new shoots and seems to be responding well to the LST im giving it.  the plants are being fed once a week with a 9ml/1L of yates all purpose thrive from Bunnings.

Almost looks like leaf miner damage on some of those leaves, but doesn't seem to be as destructive as you would expect. Regardless plants don't look too  stressed about it, check under leaves etc see anything?

yes if you google images for leaf miner they have a very distinct 'munching' pattern
