Im new to this site, I was wondering if anyone can help me with a problem I've been having? When flowering at about wk 3, I notice that the plants start showing a pale green colour to the leaves. Then the lower fan leaves start becoming yellow with brown spots. I have hard water so I thought i had too much calcium, so I purchased a reverse osmosis system. Im thinking it might be nitrogen deficiency but im following the adv nutrients calculator at a moderately light feeding program but I still see signs of nute burn! Some plants also have red stalks while others of the same strain dont. I foliar feed epsom salts and they got better for a few days but then they got shitty again! Can anyone HELP! Thanks
