Greetings icmag. Ive been absent for a while. Life happened, kids, work, kids, work, fun..did i mention work and kids?
I'm here in the infirmary because 6 months ago I began a new project and my plants have all been seemingly infected since moving into this home. Let me give a quick background. I've been growing indoors for 15 years and have grown all these same strains for years in other spaces. I consider myself well versed and have dealt with seemingly most
all of the problems that cannabis growers run into. I consult for a number of growers in the town i live in and spent years on the forums learning, growing, and fucking up. Thanks for reading this far now stick with me here because this is not going to be an easy answer.
The space I built this grow in is in a dry mountainous climate, but the home actually has a seasonal spring that comes out of a granite slab under the home in a massive 20ft ceilinged space. I'm growing in the garage next to this space. The lower level of the home which is this granite slab room and garage definitely had a musty mildewy smell when i moved in. I've cleaned and filtered the air in the garage but the basement room next to it is not cleanable as it is raw earth and insulation and essentially a cave. Thats the lay of the land.
I've spent countless hours trying to find similar looking plants online. I've trouble shooted for PH, fungus, nutrient issues, fusarium, pests. I've tried a regular regimen of natural fungicides, foliar fed with teas and drenched with beneficials. Ive tried feeding them less, and feeding them more.
Onto the symptoms. Every plant in the home, which has plants in 5 different rooms/garage is showing symptoms. I brought in fresh plants from another spot of mine and they showed symptoms within a week. The symptoms seem to accelerate in lower light situations, and any symptoms related to nutrient deficiency obviously accelerate in stronger light areas. Symptoms are different in Veg and flower. Before I describe what the symptoms look like I'll tell you what I think I'm facing.
I believe the plants are infected with a virus and that this virus is both airborne AND living in the plant being passed from clone generation to clone generation. I also believe that because of so many different and varied symptoms that there may be more than one thing going on. They are weakened and other things are attacking.
At one point I thought is was Hemp Streak virus or tobacco mosaic (both of which i tested for with a culture kit and they came back negative), Then maybe fusarium but the roots generally feel strong in most of the plants and the stalks are stable and firmly planted. I'm perplexed. I've scoped for root aphids and inspected for broads and russets. No symptoms of any of those but what the hell i looked anyways.
Symptoms in veg: The edges of new growth twist and cup upwards. The serrated edges of the larger fan leaves turn upwards. Heavily blotched purple stems on all strains. Lastly and this also happens in flower is that half of a single blade of a leaf will look like it never grew or somehow disintegrated.
Flower symtoms: Random spots of leaf necrosis up to the size of a small coin. Leaves will eventually die and still hang from the plant and are not easily removed. In other words they still stay on the plant but the leaf is dead. As it gets worse the leaf loss accelerates. The way the leaves die in flower is the tips of the leaves roll backwards onto themselves like a fruit rollup(from the 80's!). This can also happen in veg. They also get a mosaic pattern on the leaves and will look a little mutated in size and shape.
Also and I've never seen this before is that half way through flower a few entire branches will look like they would if the plant were never watered and dried up and shriveled. That would spread within in the plant and by the end of flower a few plants looked as if they had died of draught. I've read this can be a symptom of fusarium wilt but the stems root systems seem strong on 90% of the plants.
I've lost about 10% of my plants each flower round to what i'm describing above. The ones that finish are yielding 30-40% less than what i hit regularly with these same strains in other spaces.
Its not a nutrient issue, temp issue/humidity issue, ph issue, co2 issue.
