Yellowing start of week 5 flower?

Hey people,

I have a blueberry muffin in flower and noticed one of the leaves is yellowing at the bottom. I'm feeding at around 1.3 Ec for this lady and the rest of her looks spot on and she is packing on weight on buds. Is the yellowing something to be concerned with or just something that happens at this stage?

Any input appreciated!

Probably wouldn't be too concerned.
Watch it doesn't start to spread. Looks like a couple other leaves are starting to show a bit, so keep a careful eye.

That's a small pot for the plant's size.
Coco coir? I'd be feeding more than once per day with plenty runoff. (10-20% pot volume in runoff minimum)

Keep it up with the feeds, should be ok.
Couple lower fan leaves isn't much to worry about.
If it starts to spread consider your input EC. There's a ton of growth and bulk happening now. And, it's lower leaves showing symptoms, so you might be deficient.
Everyone's nutes are different, but I'm about 1.2EC for veg and max out at about 1.8EC during flower.
1.3EC isn't very high, by any means, you could go higher.
As a rule of thumb, keep it under 2.0EC (both your input and waste)

I think it's mostly the small pot size at play myself, and the plant's just cannibalizing a bit. Those lower fans aren't doing much, plant's probably just making use of them.
If you're running coco coir like your other plants, I'd be feeding more than once per day, it's a small pot.
If it keeps spreading, check your waste EC and if it checks out, consider raising your input EC.

But don't be alarmed, just observe, don't act straight away.
A couple lower leaves going a bit yellow mid flower, isn't of much concern. :eyesmoke:

Thanks buddy yeah ec is quite low I wanted to push it but there are different phenos which are more delicate than this one. I think next round will be all this pheno so I can make sure she gets all she can eat. She gets fed twice a day but ice just installed the dripper so will up that to perhaps 3-4 times a day. I'll keep and eye out and report back
