Big Head Head Stash

May 17 defoliated one big fan leaf and tied it to a pepper cage as minimal LST. Staying outside overnight on warming table now. Playing around with CO2 generation using vinegar and baking soda. Using a Red “tomato greenhouse” and during daylight hours adding CO2 using about 2g NaHCO3 in a tray and adding a few mLs of vinegar. Assuming 0.5 m3 bag this will generate about 1000 ppm CO2. Tried it yesterday and the plant was noticeably bigger today but that might just be normal growth. Tried again today and it seems to work but may have overdone it a bit tonight as the plant is droopy. Not wilted or heat stressed or overwatered but I think possibly overwhelmed with CO2 as I may have added more than my calculated amount. My technique needs work but this CO2 addition might be worth it for special plants. Alright overnight low now as high as 11C 🤠 springtime in Alberta May 18: clearly co2 caused rapid growth and nutrient deficiency quickly showed up in lower leaves...will save this method for another strain. Looks like calcium and/or magnesium deficiency likely due to fast growth and my soil mix not having enough to begin with. Dolomite lime is needed for next soil mix. May 22: rain And cold last two days. Been using “tomato greenhouse” for protection and plant is still doing fine. May 23: tried a calcium citrate and kelp extract as a foliar spray with a dab of dish soap as a wetting agent (surfactant). Didn’t cause any distress and the plant looks good.
