Oaxaca x Panama regular

Since @dubi mentioned it, how did you correct your soil fungi issues? I have a 2 mo. old Golden Tiger X Panama seedling that has no vigor. Am thinking about doing a copper fungicide soil drench and copper spray, specifically using a chemistry called copper sulfate pentahydrate, a systemic. I know it is prone to pythium as I lost 4 Ace seeds and seedlings to pythium rot few months back.

My issue with the fungus was solved by not letting my roots touch dirt in my yard. I have all of my plants and peppers in bags sitting on ac infinity watering trays. All my fungal issues came from my yard being a former cotton field. No issues with fungus this year thankfully.

This fall I am going to absolutely soak the fake grass area inside my shade house with a copper based solution. I’m eventually going to do a bunch of raised beds in that area and don’t want issues after all that work installing those.

I had a vigor issue this year with a Panama haze that ended up being a phosphorus deficiency. Hit it with some high P seabird guano and boom, took off. Was kind of odd because it got the same feed as everything else at the same rates and it’s the only one that acted up.

Did some research on the Trich, very interesting how it induces a hormonal influence such that there's new root and leaf growth. This assuming it works with cannabis. Will give it a go, thanks for the info. https://link.springer.com/article/10.1007/s10725-011-9610-1

Trichoderma and its role in biological control of plant fungal and nematode disease

Trichoderma is mainly used to control soil-borne diseases as well as some leaf and panicle diseases of various plants. Trichoderma can not only prevent diseases but also promotes plant growth, improves nutrient utilization efficiency, enhances plant resistance, ...

Kicker is all products have a very short shelf life, even frozen I read on one that it's only 8 months. So, because it's so expensive you best buy small quantities. I'm researching sources......

If you want a cheap source of tric, try growing any kind of mushroom and just be sloppy about it. You’ll have freaking tric everywhere. I added about 30lbs of tric covered lion's mane substrata that I messed up this summer to my garden.

Nice! I can buy shroom compost by the bag or truckload albeit a 3 hour drive.

Hi @acespicoli looks like seedlings are showing major macro nutrient deficiencies. Seems there's a problem with soil and/or water. I would recommend to transplant to bigger pots with new soil rich in high quality dark peat and worm casting, and make sure to water in correct ph with good quality water.

Hi @Old Uncle Ben You must respect the wet-dry cycles of the soil, allowing it to dry properly before the next watering. If you're dealing with soil fungus, extend the dry cycle until the plant is almost wilting to let the fungus die and allow the root system to recover. Apply a copper fungicide during the next watering (if the plants aren't too weak) and allow the plants to respond to the following dry cycles.

If the issue lies in the walls or environment of the indoor room, the setup must be kept extremely clean and tidy. Consider moving to a new room if the spores are well-established and you don’t want to repaint.

Thanks for your time.

They're in a greenhouse with one moved daily under lights to simulate long days. The GT X Panama is getting full sun only from sunrise to sunset, latitude 30 degrees, about 12 hours of visible light. I've grown weed for decades and never had such a lack of vigor. I'm taking one of them (my OLD cross of a Positronics Haze X Posi. Jack Herer) out of its 1 gal. pot, something is not right with my current mix. Will knock off all I can and put it in clean fresh mix. Will also treat the root system and submerged lower trunk with a rooting compound, an indole-but. hormone with fungicide.

It's all about the roots.

Best,
Ben
