Afghan Cino

Installed a net to set up colas, avoiding direct contact. Had to change my oscilating fan which did'nt oscilate anymore... changed the fixed one too. Now it smells, begining to stink : carbon filter and full ventilation on. Barely maintain HR near 50% by day, 60% by night but it's OK with 24°C/20°C. Noticed brown spots, nothing alarming but I'll keep it under surveillance and gave a drop of B.A.C. Organic Grow. Almost forgot : trichromes are here, everywhere.😜 EDIT : after last watering, I measured the pH of the run off at 5,5... with a brand new and properly calibrated pHmeter. I guess the brown spots are caused by this abnormaly low pH for soil creating a few deficiencies. I thought pH was not a problem with an organic grow but for now I'll stick to pH = 6.5 for the nutrient solution using Biobizz Bio-Up for weeks 9 and 10, then I'll water with pH=7 plain rain water for last couple of weeks.
