OG Kush LED*HPS soil #1

Hello ! Looks like marks , could be pest but you need to check under your leaves , the marks are pretty visibles so I bet if it's a pest then it's a visible one ( thrips ?). It is hard for me to tell you that It could be a deficiency as you'r only on week 2 so your soil should have enough nutrients to fertilize your ladies one more week , however it's looks like a calcium deficiency ( but it would be a very very early one). I hope it will help you 😁👍
