    To use Trichoderma-- Mix 1 L of Liquid Trichoderma thoroughly with 100 L of water (distilled water) in a plastic cup. For drenching apply this solution to the root zone of the plants. However, if your plants are already at their peak, you may not see an effect from adding this microbe. Its best in the beginning, to apply this fungus to the seed and it will colonize the plantโ€™s root system as it grows. Or you can apply it directly into the planting area, when planting your living plant. Early application is important and key when using Trichodermato for good root health. You are doing a super job and your plants look amazing!!!Good luck.๐Ÿ˜Ž

      So far so good. They are all looking really good. The Golden Cobra top was pretty darn close to 100% this morning. When the sun got on it it barely changed a hair.
      I gave another compost tea this morning brewed with coconut water for it's sugar source. Probably skip the compost tea/ seaweed thing tomorrow morning and just give them some coconut water. The plants and soil always love coconut water and the gibberillins and other hormones in there can't hurt. Then I will continue with the ash, seaweed, compost tea applications.

      A little history on the test subject the Golden Cobra. It is a feminized seed, cross between a Grape Kush and a Tangie. All seeds were started outdoors April 15th. Plant is now 9 feet tall and has been growing a steady 2-3 inches a day through it's vegetative life, including when showing signs of fusarium.
      Here is the top in the morning.

        Still haven't got my hands on the trichoderma. Hopefully today.
        I know it isn't optimum use later in life, but it could help with my theory of overpopulating the rhizosphere with good organisms and making life hard for the fusarium.
        That's why I like the idea of that Mycostop, even later on. The bacteria it has is supposedly parasitic to the fusarium.
        Thanks for the compliment. I take pride in my little hobby these days. Nothing tastes like sungrown organic buds๐Ÿ‘

          Well just gave them some coconut water this morning. Brewing some more compost tea for tomorrow.
          The fight continues. Branch looked perfect this morning and then dropped within a hour of sun.

            Top came back up in the heat of the sun around noon. It's just that early morning hard pull of juices when it shows itself.
            Took some soil temps today. In the heat of the day with 95F air temperature, the soil 2 inches below the shallowest mulch on top was 72F. Not too bad.
            But when air temps were over 110F two weeks ago the soil must have broke 80F which is considered critical for fusarium formation.

              Compost tea and some EM liquid kelp this morning. Looking like she might hold today.

                She did the slightest drop for about a hour yesterday morning, then came back and looks good since.
                Some more wood ash and compost tea this morning.

                  Might want to try a soil drench with Regalia

                    That looks really interesting as well. Of course not available in Canada again
                    It does use the same concept I am using so it gives me hope....

                      All good yesterday and all good today but it has been cooler and cloudier finally.
                      No inputs today, dry out day.
                      Making my next batch of compost tea for tomorrow and had a brainstorm. The active bacteria in Mycostop comes from peat. So I added a half cup of peat to each 5 gallon bucket of tea.

                        Your plants look beautiful! Glad you are winning the fight. That's a great idea re adding peat. Thank you for sharing your experience. ๐ŸŒ„

                          Well the compost tea has continued. Finally got my hands on some Trichoderma the other day and have inoculated with that.
                          Did a bunch of lower branch pruning and only saw slight discoloration on the most obvious branches that were previously infected. But many were perfect white so it seems I have at least kept it from spreading.

                            Well I am optimistic but still weary. The top is holding and general health looks really good. Will back off the compost teas for a while and stick with the kelp and other typical amendments for the next while unless I see some signs again. But it seems the compost tea has reached a ceiling at the moment. I think I lost a lot of biology during the heat wave, plus fusarium loves the heat, giving it a chance to take hold. Now I feel the soil is maxed out with biology again.
                            Golden Cobra is a little over 10ft tall now and lower branch top looking good.

                              Those a awesome looking plants, and that has to be the best looking Golden Cobra, I have ever seen. I'm really looking forward to seeing her flowers this Fall. How much more time do you have before the start of flowers Great Outdoors, I'll keep my fingers crossed?๐Ÿ˜Ž

                                I had never even heard of Golden Cobra, much less seen one before I purchased these seeds last year. They are from a seedbank here in BC and they told me that it should be ready end of September ish. It's solidly in preflower now and that's with the full moon stalling it. By the end of the waning moon in a couple weeks it will be well on it's way.
                                I've been trying all new to me strains the last few years. I have been growing close to 40yrs but am new to the whole internet growing thing. Previous to legalization here in Canada I would never even click on anything to do with weed on the internet, let alone purchase any seeds or participate in any forums. Hence why I am a late joiner here and have seemed to missed the boat as far as participation. It's pretty dead here these days even compared to last year. Most of the good content you see on the net seemed to happen 10yrs ago.
                                My knowledge of growing came from some books and mag's from the 80's, and lots of trial and error. Good information wasn't available back then and if you wanted to advance your growing you couldn't be scared to try some new ideas yourself.
