My only female in soil at around 11 weeks... been flowering for about the last month... only problem to surface is this....(see pics)... not sure if it is from lights or nutes... I only feed her once a week 1/2 strength bloom nutes from stealth hydro so I am thinking it is a light problem... she has been climbing for the light and it is a 600w agromax HPS bulb (digital ballast) regular reflector not cooled... anyone hve an opinion??
