Looking for expert or pics of mosaic virus

That's not a pattern of damage with which I am familiar. I am going to bring this thread to the attention of a better horticulturalist.

stinkyattic Reviewed by stinkyattic on 10-20-2008. Looking for expert or pics of mosaic virus Hi all, been lurking for a long time but this is my first post. Wish it were under better circumstances. First a little background. I have been growing for 15 years and have been a smoker the entire time. Usually smoke in the rooms as they are the only part of my residences that were for me alone. Never had a problem. Recently I had an issue with spider mites. Tried several home made and commercial sprays before discovering no pest strips which eliminated them. The last spray I tried was Rating: 5

what i think, but just a thought, oh and a better one then stinky huh :wtf:

Boron-toxicity symptoms
Brownish leaf tips and dark brown elliptical spots on leaves.
B toxicity first appears as chlorosis of the tips and margins of older
leaves. Two to four weeks later, dark brown elliptical spots appear on
these discolored areas, which later turn brown and then dry up. Necrotic
spots are most prominent at panicle initiation. Some varieties exhibit
discoloration only at leaf tips and margins. Vegetative growth does not
decrease markedly.

Tobacco substitutes comprising an organic binder containing boric oxide or boron oxyacids and their ammonium, alkali metal and alkaline earth metal salts are disclosed. The disclosed tobacco substitute may comprise from about 2 to about 95% by weight boric oxide, boron oxyacid, or boron oxyacid salt and from about 5 to about 50% by weight, of the organic binder wherein during combustion the boron compound melts or fuses to form a stable ash. The tobacco substitute may also optionally include up to about 93% by weight of a filler such as CaCO3, MgCO3, charcoal, alumina or alumina trihydrate and up to about 15% by weight monoammonium or diammonium phosphate.

That's an interesting piece of info, and one I have never known up until now; however if you have a need to make jabs like that, or have some issue with me, I'd rather just hear about it straight up. My email is in my sig if you have something you'd like to talk over.

I feel people are looking in the wrong place. Toxicity from tobacco is very rare. You could smoke in the room (all though I don't advocate it, but I've done this myself) directly on the plants and they would be unaffected. Teas and tobacco sprays are very common and TMV would be a more wide spread issue across multiple cannabis forums if it were a true problem. That's not to say that you are not experiencing it; but it is to say that it's highly unlikely that this is your problem and it's more likely to be coincidental. Remember Occams razor? I feel that this is applicable here since your pictures have multiple symptoms occuring at once which would indicate a more common problem source; yet because of your recent use of tobacco you are trying to link it to a rare condition, TMV. Remember, often times the simplest answer is the correct answer. Since the symptoms do not match TMV, it is unlikely that it is the simplest/correct answer.

It's like trying to push a large square peg into a small round hole.


To be honest, and I understand you have 15 years of growing experience, but you really haven't told us very much about all the conditions surrounding your grow.

You have multiple symptoms occuring which honestly appear more to be some sort of lockout situation; which I'm very familiar with.

I would suggest that we restart the troubleshooting process by having you fill out the troubleshooting form.

We now know the background of the situation.. let's fill in the rest of the technical gaps. I'm sure with the information combined a solution will be found.

well first off sorry stinky no offense there shouldve been a period not a comma. I meant it as there isnt to many who are more knowlegdable than her dankness.

and dai brought up the fact of the sheet, good idea
i want to see this outcome cause its new and unique

[stinkyattic]

Phew! Ya had me worried there! I am totally intrigued by this too. It reminds me very much of a symptom I have seen commonly on Rhododendron and Azalea species, but Rhodos more often.

Hi All !!!
Just for the info not a diagnosis!!!!

I had a similar pattern on one of my plants after I didn't water it for a bit.
It was back in the corner and some how I neglected it. After it began to wilt
I realised what I had done and watered it immediately. The plant came out of it and is healthy again but it still bares the scares of the neglect.
It looks a lot like your pix in early stages.

Just info looks like one of mine.

GOOD LUCK :hippy:

I had the exact same issue when my soil chemistry got out of whack.. My plant had all the symptoms imaginable and I was confused as hell until I realized that my soil chem was all over the place.

There are a number of issues that could cause this. I think the tobacco is coincidental. We won't know more until he gives us the rest of the info we need.

Really appreciate the help, the situation remains essentially the same. There were some mild signs of under fertilization after flushing followed by light ferts. I plan to do the same again though on the next watering considering the possibility there could still be chemical traces as mentioned above.

The new leaves on those that started flowering after the condition appeared are generally deformed (not always) but budding faster than the ones which were healthy at flower onset, maybe due to stress. Some of the younger clones that stretched the most on flower have just 2 or 3 branch buds below the top and no leaves or branches left at all for most of the stem. It is really bizarre looking.

One of the boxes was stripped, cleaned, and repainted. I started some seedlings in that one and am not using any of the same equipment or going near it after handling any of the suspect plants. In the other box, I have some clones from a friend that may have been exposed but they were mite infested and still have not rooted so they look pretty rough anyway. They are using the same cloning container/pump as before which went through the dishwasher, but from what I have read, that may not have been hot enough if its TMV.

I will try to get some better pics up this weekend now that I figured out how to take focused close up shots with this camera. I would love to rule out TMV and avoid any further shut down or sterilization steps. A twisted positive note is that this condition appears to be fatal over a relatively short period of time and from my understanding, mosaic doesn't cause death, just unhealthy growth.

Thank you for the continued interest, this is very frustrating.

Okay- that 6.8 is DEFINITELY your runoff number and not the pH of the fertilizer you are putting IN?
GH is buffered for hydro. Earth Juice is definitely acidic as well. Lockouts occur in soil when the pH is too low or too high.
Also you are running soft water and calcium deficiency is a potential culprit. That's easy; add calmag to 250ppm before adding other nutes, and then bring your fertilizer solution pH to 6.9.
Is there any chance that there is sodium in your water? The damage looks consistent with pH imbalance and salts buildup locking out needed nutes.
