N and K Requirements during Flowering?

Should I be giving a plant 6 weeks into flowering any N? Doesn't really look like it needs it. I've been doing bloom only. Also, at this point should
I start using supplemental K? I've got Earth Juice Meta-K, but haven't been using it.

only if they need it.. my bloom nutes do not have any nitregon in it.. i do feed n at the begging of flower

Ok..thanks. I went a little heavy on the N in veg so I haven't been giving a lot (if any) after about the second week of flowering.
