4 weeks into budding, yellow, brown and dead leaves

my plants are 4 weeks into flowering, the buds are looking really healthy but alot of the fan leaves are literally dead and most of the other ones are seriously yellow. please check the pics out and c wot u think!!

this has always happened to my plants near the end of blooming, which is good becuase i wanted the nitrogen to slowly deplete, so im guessing its a nitrogen shortage and since your still going to want some plant growth try adding a lil amount of N to your nutes, not to much tho.

First off give that plant a hair cut & pull off all those dead leaves,then add nitrogen,the yellowing is natural but you want to keep the nitrogen going in small amounts through the entire grow,even while in heavy bud,it will allow the sun leaves to last till the very end.

I see some K def as well. what nutes r u using and at what strength

i was using canna coco a+b throughout the veg stage, then moved to pk13/14 for flowering. however i was told that i had been using it too much so i stopped and just gave them water, once every 2 days until water came out the bottom. the pk13/14 says it doesnt have any nitrogen in it. is has an npk rating of 0-13-14. my veg nutes contains an npk rating of 5-4-3, should i be using this for now?? thanks lot

Yes,give it a healthy dose or two of veg nutes.

yeah, u cant just use the canna PK-this is only a supplement to normal feeding regime the last half of flowering. stuff is a bit wacky with ph I find-hydro. must some type of buffer added in there or that chemical is naturally buffering. like pnahead said, feed with veg and keep feeding up until last 2 weeks.
she looks real nice thus far if the two pics r of the same plant. dont know who would tell u u were feeding them to much of the PK cause I see's not evidence of that. just the opposite. they would look alot worse than this if u werent using the PK.
next time u will probably want to invest in some proper bloom nutes, or pick up the Canna C part of that equation.
maybe you would want to go with 1/2 strength of those veg nutes every other watering and molasses in between-
