Any idea what this could be? Deficiency or overfeeding of some sort?

Hey all! Just wondering if anyone would be able to identify what is going on based off of what’s happening with some of the leaves? I just started week 6 of flower. Thank you!

Need a picture of the whole plant. Its crucial to know how high in the plant this leaf was.
So far looks like an early Potassium or copper deficiency, are you using a PK booster?

I actually just used powdered KoolBloom today along with a general feeding. Fed to an ECM of about 1700. I’ve attached a few pics of various parts of the plants.. thank you!

I posted the pics above.. also worth noting, I was only feeding to an EC of 1200 before today because I’m an idiot lol.

Yep problem solved then 1700 should be about perfect. If you feed only 1200ec so far and got to this point this strain is not a heavy feeder therefore I wouldn't try to feed more than 1800-2000. Some will like up to 2.5-2.8 ec looks like you are gonna be saving some money!

Overfeeding, to dense, lacking air flow and light

I mean if you don't have insects or Powdery mildew you are cool, Prophet from Crysis 3 is right tho you could use a small upgrade in ventilation, you should get a double pack of the vivosun small fans for 25$ they are awesome I got 10 of them.
How many ppfd you running? co2?

whats your runoff ec when you water?

Those leaves are gorgeous, what are you running?

Also, I agree they're a bit overfed, but they look good overall.

Could it be that you don't flush properly or at all when you water? because if the experts here are saying that they look overfed but you feeding 1200ec only thing i can think of it that you could be not flushing and accumulating salts in the medium while thinking you are being conservative. Let us know

I actually did a flush 2 weeks ago because I was worried I was actually over-feeding. i haven’t really been checking my runoff EC, but I’ll definitely do that when I water on Sunday. Someone above said they look a little overfed, which has me a little nervous now that I upped the EC I’m currently running 4 Spider Farmer SF1000s. One per plant. I appreciate all your help btw. Ive only done about 4 grows and im still learning things with each one. You reaching out means a lot.

You got it G, Its very great that the growing community are very solid and positive no matter if we all have different takes on the matter. Definetely check soon as possible, you can even water again, slightly overwatered is better than burnt

Slightly overfed - ( tip burn )

Sativa plant will need to run as long as needed to finish properly ( regardless of breeder info ). They look quite good.
Plant could use a little pruning to allow lowers more light and better air exchange thru plant.

I’ll definitely do that!! I’m worried they’ll stop putting on weight soon.. Today is the start of week 6. Will they still swell for a while?

I would say so and hope so because looks like they just put foot on the door so year i think budzbuddha is right probably your pheno needs more time

Sativa cannabis strains typically have a flowering period of about 10 to 14 weeks. This period can vary based on specific strain genetics and growing conditions. Some sativas may flower a bit quicker, while others might take longer, especially those with strong landrace genetics.

Also , The buds of sativa plants tend to be less dense and more elongated compared to the compact buds of indica plants. Yours are stacking up hence the sativa aspect. Cat turd , spears , elongated , nug shapes …. Many forms.

Keep going.

Ok.. thanks! I was wondering about that, because it said a 60 day flowering period, which comes out to about 8.5 weeks. Week 6 started today.. Think I can do another feeding at the start of week 7 before I flush?

Sometimes you get some hellish foxtail buds … ugly as Alina habba but smokeable.
Grinders don’t care.
