BM Special Queen #1 from seed

Its the end of week 5 and the girls are really sugaring and bulking up. This is my first time growing this strain and the trichomes are really starting to develop. I can even see sugar on the big fan leaves at the top of the canopy. I must be doing something odd when I feed the girls, not just this strain, but also the White Widow strain. I find that the girls always start to show nitrogen deficiency in week 4-6. I know it is normal for some leaves to yellow, but I think there are too many yellowing leaves. I think my problem is either having too small of a container for flowering, hence not having enough stored nitrogen in the soil and plant. Or I must be keeping too much vegetation. I am going to place them in bigger pots next time. Updates this week: So I started to do some limited Defoliation this week. I don't have to do much for this strain because the lower leaves fall off every two days, so I am just taking fan leaves that are blocking lower bud sites only.
