Beginner's Big Bud & BCN Critical XXL

Its Day 33 and the autos have already showing pistils on the side of the new growth mainly starting from the top colas. I am still waiting for the rest of the 3 landrace to begin showing signs of flowering, they are wild grown seeds after all and I don't think the changes in light schedule to 12-12 will trigger its flowering. Everything looks good the leaves are healthy, except for slight nute burn on 1 of the autos. I have also started the mycorrizhal fungi feed into the coco of the 4 autos just to experiment with it. probably by the time the fungi inoculate with the roots it is already week 3 into flowering. I just slowly poke in 4 holes using a chopstick, slowly insert it into the soil approximately 3-4 inches away around the main stem, then unload some of the fungi into the holes,cover in back and just lightly water around it. I have also been using a DIY Co2 generator using sugar + yeast. Does anyone here use it and yield better results? I don't have an air ppm device so I won't know how much CO2 was generated...to be continued
