38days into Flower, N def?

Hi, from the Looks, can you tell me if this is just a N -def or might it be something else? regards

hey man , ive got girls that are 34 days as of today into flowering and one of my larger plants is yellowing like yours i posted about it and people said its nothing too worry about its just part of the plants cycle its sucking the energy from the fan leaves for bud production and the guy at my local hydro shop said it looks like it was lacking calmag soo ive started adding calmag and i also give that one plant a low dose of Grow nutes again some people says dont feed N during flowering and others say its fine but my plant hasnt gotten any worse in the last 2 days since it had the N and calmag heres a picture day 34 of flower .

Cant see much yellowing but there is when u look in person

Have you been feeding it N?

churchhaze if that Q is for me i gived the yellowing plant a little N with its other nutes and its worked fine for me

I meant for the OP. If he's been feeding with something low in N, it'd be easier to diagnose that as a nitrogen deficiency.

usually N def starts down low, and progresses on the fan leaves and goes upwards

so yeah i'd say give it N asap and you'll see that it stops progressing
old growth wont get better, but it won't get worse

big mistake a lot of people do is leave out N during flower, a good guideline i like to follow is a NPK ratio around 3-1-2. If you have soil with enough nitrogen, you won't need to supply it, but say you transplanted a month ago and you just give it bloom boosters, i'd definitely add the N and slow down on the PK

I don't use bloom boosters for my own reasons (simplicity) and i focus on giving the girl what she needs
with time i will learn how to push the flowering food, but I never make the mistake of cutting out the nitrogen~it's essential for the PK to do anything

Hmm the Problem for me i guess is im from europe, so u wont know the ferts im using: biobizz allmix, grow and Bloom. Also ist a organic fert, i have no clue how Long it takes to work. i fed 3 days ago with 1ml/L grow as recommended on scheme.

Your base nutrients for flowering should have N is your ph good? could be lock out but definitely give it cal/mag. Wait 5 days to a week after you try whatever it is you try and don't just keep trying different things and some strains are nutrient whores what strain are you growing? how often do you feed every other water every third water if your growing organic it's really hard to burn them with nutrients so maybe just increase what you are already doing. Keep a journal of each specific strain cause they all are a little different. good luck

i fed them Bloom and grow, as suggested by scheme, as i said its organic. Does it look like cal mag? because i sprayed them with epsom salt solution already 3-4times. its sensi Skunk #1

change the feeding to more grow and less bloom, and you will fix your problem

but then i've heard mixed things about biobuzz, do some research and maybe check out a journal of someone who used the same nutrients, and see what ratios they did

I personally don't recommend foliar feeding for any reason, although many would disagree. Your deficiency doesn't look like Mg or S so adding epsom salts would probably only make your deficiency worse.

It doesn't look like calcium deficiency either.

well i didnt foliar feed them with epsom on this Occasion, just in the past, they did nothing but stay at healthy green at that time. As i said i fed them N, but the fert is organic, so I have read stories for it to take 5 days to 12 days to actually "start working" so i dont know if its N or caused by something different.
