Got a free seed 9 months ago from attitude. Made a mother out of it. Cloned around 30-35 cuttings in that time. Now my question is this. All of them have had the leaves from bottom to top turn pale green to light yellow. I use dynagrow bloom nutes with magical and big bud. They are in fox farms potting mix. They grow ok and I'm getting nice buds with nice frosting. The smoke is great. Is the yellowing of the leaves common for this strain? I can't see the plants having nitrogen deficiencies my nute mix is always 5.7-5.9 and I use a Britta faucet filter I just can't understand why they turn yellow. Any advice?
