Hi Guys,

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

@macky Thanks, most of those products are microbial/Mycorrhizal additives or Microbe food. I've been using Aloevate (an aloevera product) all run, but have only done one feed of the bio deisel (Guano bloom enhancer). And, after that advice from the guy at the shop, one feed and foliar of Part A + B Nutrients. I have been told that they are all organic, if anyone knows any different please let me know, coz I'd hate to ruin my medicine with bung advice from my local.

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

@zn Thanks, it's definitely not underwatering. I'll turn my blumats off for a bit and let it dry out, see if that helps. I've got a 80cm x 60cm x 210cm space with a 6 inch infinty extraction fan and 2x6 inch oscillating fans to push the air around, so I really hope it's not air flow coz I can't fit any more fans in my room 🤣

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
