Flowering week 3.75

Maple sugar or molasses will not do anything, it is a big myth. Try a couple of feeds with half strength grow and half strength bloom to boost nitrogen levels and slow the yellowing. All plants, even clones, are individuals and must be treated as individuals. This early yellowing is often caused when growers switch to bloom nutrients too early, like when there are only a few pistils. Cannabis still needs adequate nitrogen in early flower and changing to straight bloom nutrients shouldn't occur until there are small budlets formed already. What I have been doing for the last 25+ years is to continue with grow nutrients for the first two weeks of flowering, then half grow and half bloom for the next 10-14 days, before finally going to straight bloom nutrients through until maturity. This seems to produce the biggest flowers on plants that don't completely exhaust themselves before harvest. Hope this helps, Organoman.
