Do autos needs more N than photos during bloom?

top gun from atlas. plant is on day 63 about f33 or so.
plant is getting some yellowing on lower leaves. some leaves turned purple, it did get pretty cold a few weeks ago.
I don't give a lot of N in flower.
GH floranova bloom and koolbloom. pretty light feeds (250 300ppm 2/wk), but if i feed more i get tip burn.
should i give a dose of veg nutes?

it's looked pretty healthy until about a week ago it started this yellowing. the buds are getting pretty big. i was a little surprise how the buds kept getting longer instead of maturing. they don't usually do that on my other plants.

Maybe loose the koolbloom.
Floranova bloom has a good ratio of N to PK

that would up the N. I'll give them regular bloom feed and see how it does them.
i usually use KB to lower N until i use the powder stuff for a couple weeks in weeks 5 to 7, then switch back to just KB liquid until the last watering or so. for my photos, it really beefs up the buds. i get a lot more yield using it....done with and without on tents of the same strain. it's worth about an extra 50% or so.
