HSC Blueberry Cupcake clones out of control

Cool experiment and grow.
I like Blumats. It took some time to understand them beyond the videos. You need to let go some grow thoughts and habits. A single plant can be easily fed by a single carrot with one emitter. The whole top of the pot DOES NOT need to be moist. The plant will tell you what's going on, and will actually control the carrot all on it's own.
Running Blumats dry is a huge problem, because they Over-react once the water source is restored. You can easily over water the substrate to overflow before the blumat can shut things down.

Question. I just went through and picked a handful of yellow leaves off this lady. They were completely yellow and half had already fallen off. All on the bottom side of the canopy. My guess is that they weren't getting enough light so the plant put them to use and ejected them. That said, there are some yellow leaf tips that appear to be a little nute burn. Looking at the flowers, the topmost leaves don't seem to have the burnt tips. Does that mean that the problem has probably been squared away? Or does that not matter on the leaves up and down the buds? I know when in veg state,the top leaves are new growth and the bottoms are old growth. Does that still apply to the sugar leaves up and down the same cola?

Today is Day 36 from flip

Last night I plucked another 6-8 yellow leaves from underneath the canopy. Is this just because of the age or should I be upping the feed a bit? I ask because some of the leaves tips up top seem to have just a slight bit of nute burn. Just a little confused about that. Getting mixed signals. The good news is that after plucking those few leaves, I went out into the living room and my son goes, "dude, you smell like froot loops, what the hell?" Hahahaha. So I'd say it definitely has that Berry and sweet smell going on right now. :)

that is awesome to hear!

I would not worry about the lower leafs dying and falling off, it's pretty normal, they are getting less light due to those beautiful canopies, also being yellow you can rest assured they weren't doing much anyway and the plant has sucked the nutes it needed/wanted/could get from them and said gtfo..

looking at your pics I think they look excellent, that tiny bit of tip burn is pretty common, you may be feeding them up to their limits but not pushing too hard you are causing lockouts or significant burn, I would expect over the next few feedings you will start feeding lighter as they start eating less toward the end of their run. I don't think I would otherwise change anything

I'm excited for your smoke report on these.

Doubtful because it was just a few leaves and they were all under the canopy. I was pretty sure that it was just an age thing, but wanted a second opinion because the first time I grew this blueberry cupcake, I damn near killed the plant about this far in and then she ended up taking like 13 weeks total.from flip. So the 2nd half + wasn't anywhere near typical. I'm really trying to figure this strain out because it grows well, should have a decent yield, and is loved by those who have tried it. I really want to know what to expect and when as I have 4 more coming up as clones and if I need to make adjustments for them, I'll know when to do so.

Day 41

Got a lux meter for free from Amazon. I put batteries in and got readings in several places across the canopy. I know this isn't the PPFD reading that is actually what we want, but it was free and I thought I'd try it out. Don't know what these numbers mean yet, but here they are. :)

Wow I can't believe they can grow in such little pots. I have only grown outdoors and know nothing about indoor growing why is the only growth at the very top?
I have stripped everything off underneath the canopy because it wouldn't get sufficient light. It helps with the airflow as well. As far as growing big, it is in coco and essentially has a constant drip of feed.
