almost

Not even sure if this is a problem but i just noticed a blotchyness to some of the leaves. It almost looks pitted. Any ideas?

these are my babys Critical + (big bud+skunk) growing on soil with 400 watter i started adding nutrient today, i hope it will fix this, i dont have PH meter and i see almost the same in ph to high photos, can someone please verify and replay thank you guys ...
