    Default Yellow veins Gorilla Glue autoflower

    Hello guys I have 3 autos in my room getton all the same feed.
    They are growing in coco under a "900" LED full spectrum.

    One of them Is getting yellow veins on a couple of leaves, the rest of them are growing nice.

    Is this some kind of nutrient deficiency? I am using Advanced Nutrients nutes.
    Gorilla Blues are 7 week old still in preflower , I am getting some nice white pistils though

    The yellowing is actually between the veins and that's called interval chlorosis, sometimes a boron deficiency. Advanced nutrients shouldn't have a problem with boron deficiency, they do sometimes fail to get your pH in range even though they claim they can do it. I've seen guys that had to pH their water down to around 7 for the nutrients to take over and get into the good range for growing. Do you happen to have a pH pen?
