Mosaic Virus in Cannabis pics

[Bobbo4200]

Hello everyone,
I have read the entire thread over, & thier seems to be some good people that really know what they are talking about. Some people have been banned for speaking the truth-I hope they are able to come back & chime in. I am a newly licensed patient & this is my first grow. I have run into a few hangup's but I guess that's all part of the learning process. I took some cuttings last month, 2 Sour Diesel, 3 White Widow, & 3 Cheese. Of the 6 cutting's, two of the WW show signs of the virus, & maybe one Sour Diesel as well. One of the WW's is kinda bad with the leaf's eating itself. You can definetly see the Chlorophyl deformation very easily in that cut. Basically what Im asking is should I just junk that 1 WW??? Does the Virus spread by contact?-or just by the Pest vector's? The cutting's are only alittle over a month old. The WW with the MV trait's seems to be growing pretty healthy, but the cutting is still in Veg & I've read that the Virus doesnt really get bad until flower. This is my first grow, and after reading the thread, this Virus seems to scare me. Im unsure of what to do??? Any help would be greatly appreciated!

Alittle info on my operation-as it seems the more info you give someone the easier it is to help them diagnose your problem. I Veg in my closet w/ a T5 light. There is a fan going in there. I have a CFL in a reflector bowl for the clones. For Flower I move my babies into a 4 x 4 tent with a fan going in there, & another fan blowing air into the tent. The light is a 90w LED UFO, & thier is also a CFL in a reflector bowl for growth that may be in the middle of the plant. Yes, the CFL light spectrum is correct given where they are placed. (2700k for the tent & 6500k for the closet) I have a dehumidifier so the humidity @ night doesnt go above 55.

I can't let my Sour Diesel IBL go and it is heavily moscaic'D
It hasn't spread to my other girls-but then again-I don't clone at that stage so no fear of spreading plus its mainly thrips that do the spreading-get rid of them and at the least-use a separate pair of scissors on the virues'd one
*I'm usually home free if they make it to flowering stage-that and if you over feed-the virus flares like paris hilton's herp lip

chemdogD w "the trait"

Those are great pictures that show "the trait". Now to everyone trying to figure out if you have a virus notice the plants are basically healthy with the virus causing discoloration and deformities.

My plant would always get worse when growth was slowed down during cloning and with 18 hrs light, after cutting back to 12 hours it would get much better and the yeild was always real good.

Can you please post those full results?
Who tested this for you? I would have to imagine you were looking
for an answer. So...did this lab tell you it's a cal-mag prob?

A buddy at a college near me with a very good hort program had it tested. I never got a printed certificate. The plant is Og. There's not enough cal mag in the world to please her. And her yield has always been also..medium to low. But the best buds you ever had. Four five a pack type shot. Im here with an observation. Got a few others saying they have seen it too w diff strains. As far as I know most true bb. Chem. Og or any othercrosses with. Bb and. Or chem have these traits. And the plants tollerate it and were selected particularly because they showed genetic anomalies. Breeders usually see signs of pre Loren y in these traits.

^^^ interesting you mention bb, i have some blue satellite #2.2 and they did display something very similar looking, letting it ride to wait n see

I posted this:
https://www.icmag.com/ic/showthread.php?t=193806

and I said sensi star because the one plant had the most obvious issues right from the start, but I popped blue satellite 2.2 beans at the same time. A lot of the BS beans did not make it (1 didn't sprout and 3 died shortly after, 1 is very tiny/slow/deformed and the others are small and symptomatic.) It had me puzzled because the other 25 beans I popped were doing very well under the same conditions.

For everyone saying calmag deficiency, how much calmag do you use per gallon in a res (hydro) and for coco? What brand of calmag?

 

[hydr1]

There is only one brand of calmag...botanicare. many other calcium or magnesium but calmag is a trademark I believe. Anyways I use 5ml per gal with r/o and flora nova ...the flora nova grow has cal in it already.

Not suggesting the calmag cures at all. Just noting that to a newb grower it appears as though these strains are always hungry for calcium.

In reality im thinking that these plants...if grown properly and supplied with calmag in abundance will be able to finish with good results. Might wanna try it on your plants but im sure there will be mixed results...if you had a strain die and it could not handle whatever virus it had or the conditions you gave it, id try a diff approach or ditch the genetics allvtogether.

These could be different virus' all together and or your genetics cannot tollerate/did not build resistance to it......or....it is a diff virus and its much more lethal.

Alot of variables we can't confirm...if its killing plants I would def destroy and clean shop.

it dosent really look like "THE VIRUS" more like a ph swing locking out nutrients..how long have those pots been in those 4 inch square pots? maybe the yellowing is an onset from being rootbound?...you want so see what "THE VIRUS" really looks like??

this




then eventually this



... maybe there's another solution to your problem......

oh and btw cal-mag wont help if you truly have a serious viral infection in the plants....at least it didnt help me on the 2 test plants i tried it on..........

Is that a reply to me? They were transplanted from beer cups to 5" pots last week. The roots have not hit the bottom of the pots yet.

I know calmag won't help a viral infection but I'm hoping it's a calmag/pH issue. The pH I'm setting should be fine but I'd feel more confident adjusting the res using a new pH probe.

They seem to be growing so I'm just letting them do their thing to see how it turns out.

 

[vince514]

for your sake !!! i hope its just a cal-mag issue cause getting this shit sucks..and its fairly hard to get rid of......hopefully its just a ph issue and nothing more serious....good luck

 

[!!!]

vince514: I hope so. It doesn't seem to be calmag related, as I'm running 3ml/gal right now with no real changes. (setup is ebb/flow)

It might be a pH issue. My medium is hydroton and rockshale, and pH goes up far too quickly, though the res is kinda small so that might be the reason there.

From 5.2 to 6.2 in 8 floods (1 day)

 

[mr. b]

was just passing through, what is your ec or ppm? for your ph to go up that fast seems like not enough food in the system, you said the res was small, how small?

Foomar has a leaf mutation that is really stunningly beautiful! A virus induced this mutation, is that what you are saying? Many many plants have this, some are beloved ornamental plants. I have seen these once in a while, but it doesn't seem to spread, at least in my garden. fingers crossed.

Res is about 25 gallons full. The tray holds around 12 gallons per flood, maybe less. Mediums are rockshale and hydroton (pots have one or the other.)

Nutes are maxigrp and MagiCal+ (calmag).

PPM is around 750 but rises slowly, to the point where the plants get burned.. but this is very recent (first time I noticed it was today). I flood for 15mins so a lot of water is gone due to evaporation. There are a lot of salts on the sides of the tray.

Here's the issue. pH seems to be buffered to 6.0. It takes A LOT of pH-down to break this buffer and go down to 5.2-5.5. It also takes a lot of pH-up to raise the pH to begin with, which maxigro causes to plummet.

Whether I go up or down, the pH will naturally go back to 6.0-6.3.

I am using tap water, which is 35 ppm and pH 7.1. At 35 ppm the water can't be contributing much to this buffering issue?

Past few days I've also been using 2-3ml/gallon bleach (only until the res smells like a swimming pool) which raises the pH a bit.

I've never used maxigro before this grow so I'm not sure if this is normal?

 

[hydr1]

Wtf are you using bleach for? Did I miss something in the grow guide?

 

[!!!]

I got this link from an earlier thread/post..

There's an affordable easy to use test kit for TMV here (5x for $35 with shipping):
https://orders.agdia.com/InventoryD.asp?attribute_Size=5&collection=ISK+57400&loc=IN

I'm not sure but perhaps the plant needs to be old enough that there are enough virii bodies in the leaf tissue to be detectable by this test. Don't quote me on this. Please post symptoms + test results if you try it.

 

[!!!]

bleach is for running a "dead res." First heard about it from Krunchbubble here. It doesn't harm the plants. I wanted to rule out any pathogens in the res water. It's primarily used for preventing/curing root rot.

i agree
ive seen the same things in pics 2 & 3 in this thread: https://www.icmag.com/ic/showthread.php?t=193105

Wadup guys, so i have this strange growth happening on a few of my bigger plants. seems to have haulted growth and just been getting a wrinkled curly growth on the newer growth of the plant. My best bet right now is a fungus. Let me know some info of any similar experience, i will appreciate it. The strains are Bubba Kush and GDP, they dont even look like it anymore.

^^^^ very much tmv in my opinion. unfortunately. i am of the opinion the root aphids carried it from the Chem D to the affected plants. unfortunately.



!!! - had root aphids or other pest recently ?
