Magnesium (Mg) deficiency? Pics

[stinkyattic]

Well you've got me STUMPED.
That's not thrip damage. But it also isn't interveinal chlorosis in any form I've seen it before- it looks FAR too mottled. Yes, there is some chlorotic shit going on there but the pattern is very strange.
Neem oil, or BANG!, or Wilt-Pruf, all create physical barriers on the leaf surface and prevent moisture loss. Bang! was designed to be ued sort of as a band-aid after a mite infestation, think of that clear 'second skin' bandage they use on road rash and other abrasions. With any of these, apply VERY lightly, allow to dry, monitor for signs of leaf darkening (indicating suffocation), and reapply lightly if you think you still need more. The leaves should be just slightly glossier than when you began.
Since there almost certainly IS a burn going on, a good flush with pH adjusted water, finishing with 1/4 strength grow fert at pH 6.7, is a good idea. Repotting into a larger pot, if you don't have that gallon of soil per foot of plant, will also help stabilize your soil- soil chemistry gets crazy fast when you simply don't have the VOLUME to support that rootball.
This probably wasn't much help... but... ?? Hopefully Rhizome will cruise by this thread- if there's anyone who has 'seen it all', lol, it's him.

Yes Stinky that does help some. I will try the things you reccomend. I don't think it is root bound though, since it's about a 3 gallon container and the plant is less than one foot tall. However the soil is pretty old so maybe it is a good idea to transplant anyway. Would you reccomend transplanting after I have the situation more under control, or just do everything at once?

OP- when you say the soil is "old", what do you mean? Has it been previously used?
If so, what was the previous cultivar?

Do you, or does anybody else in the dwelling, smoke tobacco?

Would it be possible to get a shot of the underside of an effected leaf?

Have you had any whitefly or aphid issues?

How quickly is this progressing? Days, weeks,...?

Are there any cankers where petitole meets meristem?

How old is this mom? When was the last time she was trimmed? Did you take cuts of any of your other moms at the same time?

I would quarantine that plant.

rhizome, thanks for responding.

OP- when you say the soil is "old", what do you mean? Has it been previously used? If so, what was the previous cultivar? It was not previously used. It just seems old and crusty. The perlite on top is turning brown. 2 plants shared this container, but one was pulled after 2 months because it turned out to be male. That was maybe a year ago. It's probably fine; it's just the hydro farmer in me wanting everthing to be changed out occaisionally.

Do you, or does anybody else in the dwelling, smoke tobacco? No, and it's a new home.

Have you had any whitefly or aphid issues? No, Never.

How quickly is this progressing? Days, weeks,...? More like weeks. Notice the top growth doesn't have it, but it is all twisted for weeks after emerging. It seems like maybe 3 weeks after emerging the leaves start getting mottled, and die a month or so after that, but they are brittle from the start. This plant has always grown reeeal slow.

Are there any cankers where petitole meets meristem? No, I tried to pry back the thick underbrush for a photo of this (first photo).

How old is this mom? A year plus a little, maybe 2 or 3 months. It's been doing this for several months, but not so bad as of recent.

When was the last time she was trimmed? Never, except for completly brown leaves. Never revegged either.

I would quarantine that plant. Even if it's not pest related?

Would it be possible to get a shot of the underside of an effected leaf? Yes, quite possible. Except for the first one, all photos are of the underside of leaves. The second one is a side by side of two leaves, one of which doesn't look nearly as bad from underneith, but looks about the same on top. Weird, huh? The leaf on the right is from about 4 inches from the top, and the left one is about 1.5 inches lower. The last picture is of a leaf in it's last stages, just before turning completely brown.

I would almost say it could be a Zinc deficiency. Zinc deficiency looks like Mg but has the brown tips like you do.

I asked a question but I type too slow so I'll just edit out since it's covered above.

Both Zinc and Mg def show up as very regular striping.
That is neither.

Rhizome is hinting at the possibility of a virus spread by an insect vector- sounds like he was thinking TMV- hm. Quarantine is certainly a good idea.

I'd repot now personally. Over a year, the plant might enjoy some more room to spread out, adn you can see how much root density you have while you're at it- have you seen the threads on bonsai mums? Very neat info for keeping a mother for a long period of time.

[420freedme]

why not clone and start anew? I`ve one strain for 10 yrs now and I clone to clone. no mom. seed banks and lrg grows use this method. I've 7 strains at present and am starting 2 more. how would i keep 9 moms? no, the genetics aren't screwing up. I'ld say the older they get, the stronger and faster they grow.

perpetual grow w/no moms. easy as cheese.

[Weedhound]

A virus? Looks like the entire plant is involved...so if it WERE a virus (did I read that right?) is the entire plant "contagious?" How are you supposed to diagnose a virus in a plant???

Uh, I'm not sure what you mean here. I certainly didn't mean to igonore you. I appreciate all input.
