Organic grow, using LC's soilless mix and Gaia Green. I am about 3.5 weeks into flower. Soil pH appears to be right at 7, if not slightly under. Using tap water ran through a Pur filter to remove chlorine. Any ideas? EDIT: Possible CalMg deficiency, gonna give this a shot.
its very rare for any organic grow to show nute def symptoms check the link: GWE Cannabis Nutrient Burn good luck
