Need help quick! Ph question

so I’m growing some tsunami web outdoors in North Carolina and am about 4-5 weeks out from harvest I believe.

My recent ph test results came up with a 7 for every single smart pot, almost exactly. It’s usually more at like 6.3-6.5. Should I be worried? I don’t have any ph up and down because my nutes and soil and water have all been in good ranges. I tested just a couple days after I noticed some uniform yellowing (not interveinal) of the lower fans and close to the stalk, which started about 7-9 days ago. I am used to this obviously but usually a little closer to harvest at the rate it’s happening. Could it be related? It’s my first time with cbd dominant strains so if anyone has any insight on that variable...

Extra background...
im mostly organic.
I am very careful not to cause lockout but I tried flushing one plant just to make sure it wasn’t lockout and that didn’t make a difference.
I added just a little extra nitrogen a few days ago (before ph testing) but it hasn’t seemed to make a difference.
If the consensus is that I need to add something im willing to acquire whatever I need.

ANY help is appreciated but especially in relation to a slightly high soil ph or strain specific knowledge about flowering stage leaf yellowing.

Cheers

You're fine around 7 especially for flower. If mine are looking less excited than they aught to, I give em some kelp/humic acid mix, some L-amino acids, and some epsom salt. Foliar in veg, watered in in flower. I get the first two items in bulk powder form from kelp4less.com. Greens and perks everything up instantly, cross my heart.

Not that it's related, but the Blue Ridge area is probably one of my favorite areas of the country. Love, love, love it. Everyone should put Asheville on their travel list.

Thanks. I do give Humic acid (ful-power), l-aminos and occasionally Epsom. The yellowing seems to be slowing a bit but not stopping... I can tell the plants with the worst yellowing are having slowed bud growth. Wish I knew exactly what to do. I don’t want to overdo it trying to figure it out :/

You don’t think it could be a nitrogen dificiency?

Agreed. Asheville is where I’m at actually except we’re so swamped with tourists and people moving here that I hesitate to tell people how great it is, haha.

Could be. Kelp has a small amount of nitrogen and depending on what kind, a good amount of potassium. Mixed with humic acid at 5 parts humic to 2 parts kelp, it has also been proven to increase calcium uptake and increase brix content, helping defend against temperature swings, sucking insects, and mold.
 
How's that plant doing? You are welcome
They’re doing fine. I had to cart them two by two into the barn for this hurricane unfortunately but I’ve got a few grow lights on em and the ambient light from outside should keep them alright for just a couple days.
I’m a little stumped on ph again in that they still keep coming up right at 7 (the soil) but my water and my nutrient solution is usually around 5.8. I know it should be more like 6.2 for soil but i wonder if because my soil is a little high of it balances out or maybe it doesn’t work like that?

I took some pictures... I also recently sprayed them with green cure because of a small amount of pm but don’t think I’ll do that again because, as you can see, they got all these little dots that turned brown. Hmmm.
But overall they’re doing ok. Especially considering I rescued them from someone who had them in solo cups he first couple months.
The second one is of one of three that were extra small that I decided to just keep outside during the storm as their buds are not very dense. They seem to be way behind the others in flower development, not sure why. Just stunted I guess.

Looks like a calcium def to me.
 
Just curious...I've always been under the impression that these types of soil probe meters are very inaccurate. Do you use the same thing to check the PH of your nutrient solution?
Yes I’ve wondered myself how accurate it is. Obviously it isn’t digital so it can only give me an idea, rgive or take a couple tenths or so. It is not meant for water however and I use a more accurate digital meter for my nutrient solution and water.
