    Looks a bit underfed, Mg or Sulfur to me. I'm a nub tho so better wait for someone else.

    oh and btw its not nute burn imo looks like a nitrogen def to me from pics ive seen online. you should check out the sick plants forum here and see if any of the stickys can help you identify 100%

    This is exactly why you give them a nice shot of N the week before the switch. ;)

    When you flip to flower you'll get top down defs like this because the budding process is initially nute demanding. It'll suck what it needs out of the leaves to get going quick and then catch up as the feed increases.

    When you see yellowing like that from top down in flower check your pH first to ensure it isn't lockout, then give a stronger dose of nutes.
