HELP! Magnesium shortfall / soil

[SnowDog]

Hey GWE community, can you take a look at these 2 plants and advise on leaf changes?

First pictures are Jack Herer AF in week 11 from seed. Looks like magnesium shortage, maybe? Please advise as I’m a newbie!!!

I'm older but a newer grower, what are you feeding them? Have you checked the plant/leaf problem identifier on the main GWE site, with pictures? Nugs look nice in your 2nd pic. I don't know about growing Jack Herer but some autos love cal-mag. I'm sure a pro will chime in. Good luck!

I'm pretty sure what you're looking at is the plant's natural tendency to extract nutrients from its older sun leaves during bud. The overall health looks good and I personally wouldn't worry about it. If you're concerned about magnesium you can always add some Epsom to your regular water routine. When my plants are in full bud I will add Epsom and molasses to my schedule like twice a week. The buds appreciate the magnesium and the microbes in your soil like the molasses.

Looks like magnesium deficiency. Not a severe one at all. But she is telling you she wants some more for sure

Of course if the PH is off then it may not be able to use whats there.

they don't look bad at all. at 11 weeks for an AF it is likely the plant drawing up all the remaining nitrogen from the leaves. Just make sure you water only when needed and make sure the PH is in the proper range for Soil or Coir. That one brown spot looks like physical damage (human or pest).

On a side note trim away some of the lower fan leaves for better uptake to the buds.

I’m pretty much all Fox Farm nutrients and soil. I’ve been adding more Cal-Mag recently ~5ml/gallon. Thanks for your comments, much appreciated.

Cool, I’ll add more Epsom salts over the next month and hope those buds keep growing!

 

[SnowDog]

Awesome and thanks. Just a little freaked out. Doh!

Nothing really wrong with those plants. Not that I could see.
