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

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?

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

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

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

The red petioles (leaflets?) may be strain-related and not a sign of distress. My Raspberry Cough did that in the second half of flower. i thought "oh no; something is wrong!" but as the plant showed good health and growth otherwise, i became convinced it was a feature.
I would not worry about pH. If your plant grew well before, the pH is fine. It won't have suddenly undergone a step function.
Has the plant in question perked up any since aerating? cn

Re: Has the plant in question perked up any since aerating?

I think so. They lost the droopiness. Coloration has not worsened. Bud growth looked minimal though. That one plant gets the worst light of them all. I untied the branches so they could reach more light. They were all LST'd/suppercropped so it got pretty dense.

Here is a larger view. The problem area highlighted. The other branch/top to the right also had the same appearance. But none of the rest of that plant, nor the others. I think they look OK aside from that.

That does look better. And the rest looks good. I think you're in the clear. I will think good thoughts in your general direction for bud weight. cn
