On week 10.5. Using FoxFarm Ocean Forest and Happy Frog combination. About 1 gallon RO water per day with GreenLeaf Bud Explostion PK Booster. Thought there was some calmag issue so I've been adding some epsom salts to the water and spraying some calcium foliar on the leaves.
I would avoid foliar during flower at all costs. That is a big no no. =] If these are autos. 10.5 weeks. That's a normal time frame for them to start fading color. ESpecially if its getting cooler temps.
