day 29 flower, nitrogen deficiency

hey guys,
so I had to go out of town for 2 weeks. had my friend water my gorilla glue 4s whle i was gone.
Im growing completely organically, and well. I guess i didnt time the amendment ( growilla bud) timing down pat, because when i got back, a lot of the bottom leaves were crisp and falling off, and many of the remaining leaves are yellowing. The buds and sugar leaves look great, considering its only been around a month.
I know its probably a bit premature for the fans to be turning yellow, and I know its probably due to nitrogen deficiency. I'm wondering, is it too late to give a light N foliar spray using the growilla veg?
Obviously a very weak solution.
I dont want my yield to suffer because of nutrient starvation, but i also dont want the spray of veg to ruin taste, aroma, etc.
the second i got back, I added the correct amount of growilla bud amendment to each plant, but i know its a slow releasing formula. Would spraying a bit of the veg amendment be overkill? should I just let it ride out and keep with the plan of using growilla bud?

would a foliar of growilla veg even do a dent in the yellowing?

Again, the plant buds look thick and pretty. Its the yellowing this early on that's upsetting.

I don't foliar feed much past middle of August. I've never had good luck slowing down yellowing with organic amendments that were top fed. Maybe if you get a tea on there as well it will go up faster. But this is when I might say fuck organic, I want this plant healthy and toss down some water soluble 20-20-20 to recharge for finish. Good luck!

Just grab some Nitrogen from NPK, don't over think it. A little goes a long way and you should see them start greening up with-in a day. This is good to use at the end of flower when you are flushing/reducing nutes. Most nitrogen is nitrate nitrogen which washes out way easier than other elements and causes premature yellowing! Peace

Just cut the leaves off plants don't need them anyway.
