White veins

[JayBee]

HI All-

As some of you may know I am new to growing. I am around week 3 now since germ and have been in hydro system under HID for just one week. (first two weeks were rockwool under T5)- Some of the leaves main vein (vein that runs length of leaf) have turned white, is this something i need to be worried about?

Thanks!

JB

A picture sure would help. Hard to tell what you are talking about without one.

probably heat issues and / or too close to the lamp (and/or perhaps too many nutes) . Perhaps I m wrong , some pics would help to find whats really causing it.
