Ok, Ok.

You should STOP feeding "N" 10-14 day's before you START your flush dirt or hydro.

Sorry for yelling but I needed to make the point.

The reason is this:

The plant will use up the stored chlorophyll and speed up the cure time. There is no need for "N" at this cycle of life, you are cutting it down in a matter of weeks anyway so make the plant use up its stored energy and produce large fat flowers.

When you cut and trim then cure properly this will save you several weeks off the cure time for good quality buds.

Check the FAQ of drying and curing your buds so you do it right if you have questions.
