Am I right in thinking this is nitrogen deficiency?

Hello yeah,same problem again,It seems to be the One you had.Yellowing progression from bottom,got some leaf very dead and calling off,same folours and crispiness as the One on your thread.How can I help those plants?
Using biobizz too.
I Lost two leaves already,big fan leaves.Also on day 39,6 week of flowering,very likely ti your issue

My yellowing was pretty aggressive when I had this issue, and I was sure that it was going to progress to the point where I had no leaves left (I'm on day 79 now, and I have too many leaves, I wish they would start yellowing again and fall off to save my efforts trimming in the very near future - hopefully my flush sees to this). I have got quite a bit of nute burn going on here, which is a result of me trying to fix the yellowing.
Anyway, what are you feeding them in terms of strength? I'll gladly offer my experience as you are using the same nute line as me. Also, what medium? BB Light Mix?

Soil:light mix Bb
Nutes:Bio bloom Fishmix top max
pH down and up biobizz
Soil pH:last time(3-4 days ago measured) 6,5
Run off ppm: (same as above) about 500
Alg a mic foliar feed Yesterday (and watered a hour ago only 120 ml both because the temperature here in South Italy Is about 30 deegree and leaves were drooping but the soil I can feel It s moist underneath the surface)
Speaking of your plant,Just use water,It Will let nitrogen get away as I did with my fisrt grow where the plant was toxic in N,used only water and started to Yellow very nice.Also,your plant Is beautiful,I am a newbie and second grow where the First One yelded poorly 10 grams
For sure, she's on straight water now, she's coming down in about 3 or 4 days brother
One thing that stands out to me there is that you don't seem to be using Bio Grow, is that correct?
Exactly,but I don't think this Is the issue here,I know that you can still use Fishmix until the endFor sure, she's on straight water now, she's coming down in about 3 or 4 days brother

Sorry yeah, I misread the Fish Mix - yo ucan definitely use that in place of Grow, and I actually believe it's recommended to do so.
What strength nutes are you giving when using Fish Mix and Bloom? 1/4? 1/2?
The exact amount showed in the schedule,100% strenght 2 days ago.Last Fed was that one

Ok, just be a bit careful with full strength - I did the same and ended up with nute burn; I gave her quite a bit every feed though, so I'd alternate plain water and full strength feeds (if it was my plant, I'd drop to 3/4 strength).
With the BioBizz organic line, the nutes aren't available the moment you fertigate like they are with synthetic nutes. I spoke with BioBizz about this directly, and they said that ~30% of the nutrients are available at the time of fertigation, and the other 70% become available over the next 1-3 days. Essentially, what this means is, you won't see if your feeding has slowed things down until a couple of days have passed.
Going back to your issue, if you have only lost a couple of leaves by week 6, I would keep doing what you're doing and put that down to the natural progression of the plant. You'll always lose some leaves, especially the ones that aren't receiving light.
