Sick Plant Yellowing rust spotted leaves
I noticed some yellowing on the lower fan leaves 4 days ago and now it is climbing up the plant and rust spots have started popping up.
I'm growing in 40L Living organic supersoil, in a fabric pot. I did 10 weeks of veg, long I know, but it was my first mainline and I wanted to give the plant plenty of recovery between toppings removed link
I flipped it just over 2 weeks ago. 1 week into flower I noticed burnt tips, which I thought was nutrient burn, so I just gave it water for 6 days. I then started to notice yellowing and gave it some Bio Deisel (2ml/L) and Aloevate (5ml/L) in 2 Litres of water, that was 4 days ago.
The yellowing and rust is still spreading.
This afternoon I bought some Green Bio Deisel (part A) and Diamond Bio Deisel (part B) after the guy at my local hydro shop said it is most likely nitrogen defiency. I gave her:
Green (3ml/l) and Diamond (3ml/l) and watered 1 Litre straight in and but 4L in my blumats resevoir.
I would love a second opinion, and third and fourth. Now that I've given her another feed I'm really hoping it's not nutrient lockout.
P.s I don't water to run off so haven't measured E removed link

my local hydro shop said it is most likely nitrogen defiency
It doesnt look like nitrogen def mate, I would say it looks more like a Potassium deficiency. Which would also fit with your stage of growth. For living soil, you do not want o use bottled nuits. A little is ok, but you seem to be using alot. I would cut back on all of that and just use some microbe tea and black strap molasses i think.
But it isnt nitrogen def mate, please dont take advice from that guy again lol
I would say either underwatered/overwatered or your extraction isn't working too well...this can be caused by stale air in the growspace, I have the same issues in my veg tent but transferring to the flower tent they go away...veg tent is not extracted very well
I took some photos of the whole plant in better lighting if it helps the diagnosis. By the look of those droopy tips I'm leaning towards overwatering.
They do look a bit N deficient, maybe that 10 weeks was a little much although not needing as much N now that theyre in flower but yeah, overwatered would be a good call...difficult to lift pots to gauge I'm guessing, lol
