    Default Deficiency or burn? pics

    This just started. I'm guessing magnesium deficiency. But if I'm wrong someone please help me out? I doubt I've gone overboard on fertilizer. Any help appreciated.

    Doesn't look like magnesium to me. I'd suspect pH or roots that are trying to breathe, or both. cn

    Typical burns, like the usual "nute burn", are from an excess of easily-absorbed nutrient. cn

    yea this just started following like 3 rain days in one week. The other plants right next to it don't show the same problem (just those damned reddening petioles)

    Bad part here is the surrounding soil is somewhat clayish so drainage may be an issue. (the 5 gallon sized hole it's in was prepared with a better mixture of course)

    Any course of action you recommend?

    Just to clarify, it's in it's own hole.

    Edit: re: aereate

    Sounds like a hermie.
    Seriously, use a long probe to punch some air holes. Roots need to breathe, and rained-down clay soil can have a smothering action. cn

    Thanks. I have just the implement of destruction for that. That clay soil was a blessing all summer long though. Hardly had to water at all during the drought, they never wilted in the slightest. I wish it never ended now. LOL

    I've aerated with long skinny tines. All of them not just the one. Also went ahead and gave all them a treatment of epsom salt and water at 1 teaspoon/gallon.

    I notice that problem is only present on 2 branches/tops. Is there any reason to really worry or do anything about the issue any further?

    I don't have the money for any PH tester, plus I couldn't find any way that clearly said how to test soil PH other than a lab so I doubt I'll be able to determine that possibility.

    They have developed a bad/worsening case of the red petioles since budding began, despite getting plenty of fertilizer. (N included) Been reading that may be normal for certain varieties. Is that anything major to be concerned with?

    All have minimal yellowing of lower sun leaves, growing and (I think) looking pretty good overall etc so I would hate to OD them with too much "care" this late in the game.

    This forum may be causing me some plant care related obsessive issues. Harvest is the only cure. LOL
