Nitrogen def?

I'm about 4 weeks into flower & a few of my lower leaves are starting to yellow. The bud still looks great just don't want this to turn into a bigger issue that can harm them. I'm figuring it's a nitrogen defiency due to me only feeding them big bloom which is very low on nitrogen. I just ordered some dynagrow that'll be here Monday. Just wanted a second opinion if I need to make something happen sooner than then or will she be fine until Monday.

Looks like she needs some cal mag too. You see those round brown dead spots on the leaves? That's cal mag def. Id give her a dose of cal mag along with some N.

Oh yeah, she'll be fine till Monday. Nice plant bro.

Ok cool! Lemme go ahead & order some of that asap as well. Appreciate it man.

that looks pretty normal to me how long does she have till she's finished? I'd be Leary of adding too much nitrogen if the plant is close to the end of it's life cycle she isn't going to use it anyway

I'd say atleast 3 more weeks, more on the 4 side. I was just gonna feed her some nitrogen one time to help her bounce back. Then she'll be back on reg program of ff tiger & big bloom for another 2 weeks then I'll start flushing.
