okay, so i definitely have signs of nitrogen deficiency at day 19 of flower.

the lowest two levels of fan leaves are starting to yellow pretty heavily, and my stems are turning red throughout.

i know yellowing is okay as the plant sucks nutrients from the lower levels during flower, but how can i safely give an extra bump of nitrogen just in case? i was going to give veg nutes for two more weeks (along with tiger bloom) per the fox farm schedule, can i just bump up the concentration slightly to fix the deficiency?

You could top dress the soil with some worm casings - it's only 1-0-0, and is full of micros, but no more N after 4 weeks

This is happening to my plants too, they arent in danger or anything but they are a couple weeks in flowering and im getting A LOT of yellow leaves, but this could also be due to wildfires around where I live, its been super smokey and I know my plants cant be liking it...should I pump em up w/some nitrogen? ive been feeding them a lot of bloom nutes by the way....

The plant will start to turn coulour during flowering i would not add no other nutrients on the flowering ones.The red of the stem why do folk get into a big thing about this if the rest of the plant looks ok leave it be.Just remove the yellowing lower leaves but only when the leaves are all yellow.

A little is ok, but don't pump them up with N, or flowering will be reduced and N tastes like crap.

Also don't cut out all veg nutes until the 2nd week of flower, and your foliage won't die off so fast.

Thanks for the advice man, but yeah they are past 2 weeks flowering now so im not worried and i'll just keep feeding them the bloom nutes, the buds seem to be growing just fine and fast too...and plus the wildfires I was talkin about are serious right now...it fuckin sucks I feel so bad for my plants, every morning I walk out and can see a haze of smoke...the air sucks...and I know its affecting them but they should be fine, some of the leaves are curling though cuz of the smokey air...
