I think another 4-5 weeks . You need to look at the trichs in many different spots and then average it out. Buds should be firm and heavy with most of the fan leaves grown over with bud mass. The trichs are great for fine tuning but you need to build bud mass! Cal mag or b52 will really pump them up i would run one of those nutes for a month then flush for a week or two before harvest! Dont let anyone tell you that cfls cant build thick hard nugs , they most certainly can when used properly! Buds should be too firm to squeeze flat once they get past that "fluffy" stage you will see just how much the develop. Your upper cola or colas should be almost to heavy for the stems to support trust me its well worth the weight.. You can see my last cfl nugs in my first journal its dated pretty well so you can know how much further you need to go..
