What is this and what can i change?

Hello. I have a cream caramel auto from sweet-seeds that i’m trying and it’s my first time growing this strain. I put it in a 19L pot with allmix biobizz and fed it water until 3 days ago i added biogrow and fishmix. The plant is at 15 days under a 250W LED light which is at ~40-50cm from the plant with a schedule of 20h on 4h off. I noticed these yellow lines bordering de leaves but i can’t find anywhere what it is. Could anyone help me?

Light maybe a little too intense for it's age? I would back the light off to around 60-70cm until it grows up a bit more maybe but i'm a novice at best so hopefully an expert will chime in.

Nothing to do with the light . Soil is a bit rich that's all , looking good . Don't start over feeding with nutes. Keep ya EC round about .6

A bit early to be pushing nutes in all mix which is nutrient heavy to start with.
