3 to 4 week till harvest, hand full of wilting leaves?

[imlovennuggets]

Hey all thanks for any info in advance. Only 3.5 to 4 weeks left till harvest for my og kush auto fem and about 3 for amnesia haze auto. Noticed a few days ago mostly with the og on two of the branch offs from main cola some dead looking leaves and a few wilting ones. It's only on the 2 beach offs not the whole plant. I've done the same as all my grows past 2 years but this is a first for me. There are a few leaves on the amnesia like this too.
My ph is good I check that when watering and there is good drainage as well. Don't believe overwatering since it's just these 2 beach offs vs the entire plant. Temps are in mid 60s to low 70s. Watering lightly with fox farms have had very slight nute burn on very tips so dint believe it's lock out or anything. My humidity is lower around 30 percent but the leaves are not crunchy and dry. So any input would be greatly appreciated want to get straight since the last few weeks of budding.

Here is a pic of plant to see it's just the 2 branch offs I'm comparison to rest of plant

That's got way longer than 3 weeks left she looks like she's just started flower

at first glance I think you are having lighting and ventilation issues. What sort of light and how far is it? What sort of airflow do you have?

They have long inter node distance, so I wonder if the lights were too far away earlier in the grow, and too close now.

Are the damaged leaves at the top on newer leaves, or at the bottom on older leaves?

I agree this has way longer then 3 weeks, it barely just started to flower, that's actually pre-flower stage..you not even really entered bloom yet... I'll let other chime in about this issue's going on, but you will want get that under control rather quickly to help get her to finish line...

I see curling & canoe leaves, which sign of high humidity/heat or ventilation/ air-flow I'm also seeing what looks to be ph on edges of leaves.. but maybe someone else can confirm that..

Thanks for the reply, I was going off 4weeks to make 11 weeks total maybe due to my issue it is budding slow. It's been growing buds past week or so. Anyhow I'd let it go till trichomes show would be ready.
The leave problem is on older leaves at the bottom but just on these 2 branches.
I'm using a 450wt led and it's been right around 20inch from top of plant. I used this the past 2 grows at the height even a bit closer with no problems. The humidity is down at 30% and it's just in a bedroom closet so I have fans in the room but with being colder the door has been shut way way more then in summer when leave it open with Windows open too. My other plant doesn't have any problems except maybe 2 or 3 leaves.
Ph level is always right about 6ph when I water.
So maybe it is as your suggested bad air flow/ ventilation. That is the big difference always have door shut this grow then always open?
@green genes the long internodes maybe since this was a week behind from other plant so light was a tad higher at first and also I flipped light to flower for my other plant so the og may have missed out a week or 2 on some veg.

Can see the top of plant better here. Is that nute burn on the tips?

Just came to mind, 2 of you mentioned air flow ventilation possible issue. The 2 branches having the issue and few leaves on other plant with same issue are against the back wall of the closet. Since I'm following the same steps and such as my other successful grows (light distance, ph checks, nutrient use) I'm wondering if it is air flow ventilation. I only noticed the issue mid last week and shortly before is when I started keeping the door shut all the time with it getting colder. I wonder with not getting fresh air in to circulate from door shut all the time if that's why the leaves at back of plant are having the issue vs whole plant with not getting fresh air. That is the only thing different the door being shut. So I am going to keep the door open with the fan going to push in fresh air and see if notice the cannoning die off. Any other thoughts let me know. Thanks everyone for the input so far

A pH of 6 is a little low for soil and flowering. Other than that, I'd agree with above, looks like a ventilation / temp issue... especially given you had no issues thru the warmer months when you could leave things open.

Ok thanks for the info @Arthur . The test solution I have says best ph between 5.5 and 6.5 I usually aim more for the 6.5 7 area then 6. I just got home from work and opened it back up and have a small fan now blowing air in from the room over the plants. No never issues this past summer except to high of temps 90s! But didn't have this happen so maybe it is just as simple as the door being closed past 2 to 3 weeks.
Also thoyght my other plant may be ok because the fan in the closet was blowing much more over through the plant than the plant with the issues.
Pic below is the top of the one branch off and the light is about 2 feet from this top. Only the 2 branch offs looks like this and the small buds that are at the nodes look like they are dying off. The rest of the branches and plant are ok though. These2 branches didn't grow tall and more in corner and bottom closet so maybe no air flow was getting to them.
But will leave things open see what happens.
