good point, those plants are mature
maybe bump up the P a little bit? or if your room has light leaks.. those are the only 2 things i can think of... are you using a HPS

i went really light on my dry nutes and my plants showed sex in 4 days under a 400w hps with 30 days vegging--and that was from seed
UMrocksmysocks Reviewed by UMrocksmysocks on . 2weeks into flowering and no flower? It has been 2 weeks and 1 day since I've switched my plants into the flowering phase but so far there has been no sign of flowers. How long does it take after switching to 12/12 that flowers appear? I am still using 20-20-20 fert and is planning to use this throughout the whole process until next crop, is this fert affecting the flowering? Thanks! Rating: 5
