Interesting leaf spots

Good morning everybody -

I have checked the sticky threads above and some other resources on the net however I am having issues 100% identifying this assumed deficiency - it seems as if the bottom, larger leaves are becoming a pale yellow with some spotting on the larger leaves. I will post some pictures here and that would be fantastic if anybody could help out with this particular situation.

Thanks all!

hungry??to early to cut out grow nutes

Looks like Nitrogen with a side of calcium.

what do the top leaves look like? entire plant? I agree with @NaturalFarmer but could also be overall lack of nutrients too.

Only the bottom fan leaves are affected so far - otherwise the plant is doing well. I have been doing light feedings using Biothrive Grow (image below) ; perhaps I will slowly increase the feedings and a little bit of CalMag?

Would be a good idea to show a picture of the whole plant even if it looks good to you..
What medium or soil brand is the plant in?
What size pot?

Using a 2 gallon pot with organic soil no added nutes ; just Canadian spagnum, perlite etc.

Auto flowering, about half way through her life. Cheers!

Adding a few more pictures here - thank you so much for all the helpful replies so far!

How long has it been in its bucket?

that plant is eating itself feed the dam thing

She looks hungry for just about everything.

ya id have to agree with thumper, you def gotta feed it

Do you have enough drainage in the bucket?
There should be some holes on the side, as well as the bottom.

This^^^^^^^^^^^^
First.
Before any feed.
How long has it been in the bucket too? How long has it been eating that soil?
Let us all know. Please.
It could be a few things, feeds likely.
But paint us all a picture.
You havnt given enough information.

Good afternoon everybody ; thanks again for all the replies.

I had drilled holes in both the bottom and sides of the bucket ; it has been in there since sprout as I previously have never transplanted my autoflowers. Same soil and I have found it to have pretty good drainage. I certainly don't want to feed if there could be another issue at play.. Cheers!

IMHO,
If the drainage is fine.
Its been there since a sprout, with no nutes.
Id be tempted to hit it once, with some veg nutrients. Something high in Nitrogen.
Probably a PK booster too. If you chooose a PK, make sure pk isnt too high on your veg bottle.
It does sound like its definitely hungry. Give it a good hit of everything.
Not too much though. Its been hungry for a while. Too much will shock the shit out of it.
Id be inclined to feed half the recommended dose. Then give it a few days, and see how it goes.
Id recommend liquid organics too. You need something fast activating.
Hope this helps
Good luck.

Something higher in nitrogen, than this ^^^^^^^^^
The pk levels on that bottle are fine, if you're gonna use a pk booster too.
You need more NPK.
Definitely more N. You could probably use something with 8% nitro, or so.
Dont go heavy on the pk. Not yet. But a little more, will help. None the less.

If this bottle was a 8, 3, 3. I think it'd be sweet. Its just the pk is a little high IMHO.
But 8,3,3, or something similar, would be great. If you had the option to supplement pk as well.
Imho, its nitrogen that it needs, most of all.

Yellowing with the spots looks like low Mg kicking in that some Epsom Salts would help with but likely lacking N as stated. As low Mg gets worse the spots will go brown

The thing with autos is they are vegging and flowering at the same time and need full veg nutes with some flowering nutes as well. Plenty of N until a couple weeks before harvest when N can be lowered and K especially be increased along with sulfur to boost resin. Epsom will help with the S too.

I found this feeding schedule a few years ago on another forum where the guy was well known as an auto grower so it might be worth reading. I've never grown autos for yields but have just to make more seeds of the same strain and try to breed my own auto strains with regular plants.

Good luck!
