Leaf discoloration on early leaves

Hello, I’m on day 18 ( early veg) and I’m starting to get some discoloration on the bottom two leaves. I’ve attached a pic. I removed the leaves. Any thoughts? It’s a white widow feminized. TIA.

Thanks for the picture!
We do however need a full picture of your plant, inside of tank, and nutrient bottles from top to bottom to access if this will be a problem.
It helps us to rule out certain things and give you a more acurate indication of what could be wrong!

If those are the first two fan leafs then it is pretty common with young plants in a Grobo. My theory is they get either a little bit of nutrient burn from the higher nute doses after the first drain & fill, or cal-mag dose was too high or low. No scientific, or any evidence to back my theory up.

Thanks for the response. I’m convinced it’s harmless, but will monitor it closely.

Thanks again.
