Why did she slow down so much?

I have a decent light. The aero light se100w. See the thing is I have the grow hub with VIVOSUN and the seedling stage legit started off at 60% which even I thought it was high and I don’t even know what I’m doing. So I turned it down to 45% and then it started stretching. The day after I put back on 60%, true leave started forming so that’s why it may seem like I’m starting off with high power. I was gradually increasing it by 5% every week. Being im on week 3 at 75%. Seedling is 60%, veg is 80%, and flower is 100% for their program. I never had light burn so I thought I was doing fine but I could be wrong. I’m in a 2x2x4 with not a lot of vertical height so that’s why im mainlining
Hm. I wouldn't really listen to the manufacturer considering growing weed is illegal in China where they make them. Lol
Go by what the plant is telling you don't go by formulas or programs. There is a number (dli. Daily light integral.). Daily light integral (DLI) describes the number of photosynthetically active photons (individual particles of light in the 400-700 nm range) that are delivered to a specific area over a 24-hour period. (Cut and paste sorry lazy) Too much and it stresses out. There is a maximum. I grow my mom's under 100w LEDs dimmed to 20% and they grow just fine. With 20hrs of light....
See what I mean. Less light for longer = same dli as high intensity for less hours. But it's less stressful and more photons are actually absorbed by the plant and used for photosynthesis. If it's bombarded with too much light it can kind of shut down.(And wilt)

See I was paying attention to the VPD and ppms, I saw something dealing with DLI but I never researched it yet. That’s the next thing I’ll do. So the praying leaves mean I’m giving too much light? I’ve seen on videos that it means it’s like the perfect amount of light. I just turned it down so when the lights come on it won’t be as bright. I say something about the program but I’m not really using it anyway. I having to do everything manual because I’m not a big fan of the programs of different stages of plant life. I’m supposed to be at 80% light right now so I just free styling it. I do exactly that, look at the leaves and they tell me what they need.

Vpd is kind of like chasing a dragon imo
I've never once looked at or cared about my vpd.
Ppms ya of course you should be pretty low ppm at early growth stages and then go up in flower or if the plant is really big. It's a bit diff for me. I run Coco coir. I can run low ppm and water more frequently. 4-6 times per day cycle I could run higher ppm and water less often depending on dry back (no no with coco). It's kinda touch and go depending on your environment and strain.
Praying leaves can be debated whether it's good or bad. I've heard solid arguments from both sides and I tend to lean on the fact that a leaf turned upwards is not getting as much light on the surface of the leaf and is actually trying to transpire more by revealing more leaf to the air. This can be because the plant is receiving too much light and the humidity is too high. There is not enough air movement removing the moisture the plant is trying to 'breath' away
Who says your 'supposed' to be at 80%. You gotta ditch that train of thought. I'm telling you the truth. If you dial down low and keep your light at least 18-20 inches away to start you will get an idea of what your plant can handle. Blasting it with light is Gona do the opposite of what you think it's doing.

Check it out
These plants are big, but trained down. The light has just been turned up to 45% from 30%. (Mars fce8000) And it's easily 2 ft away. They have just been flipped to 11hrs light 13hrs dark. They just stopped wilting at the end of my cycle telling me the light % is what they can handle. Once flowering starts going good I will start upping the dli until I reach ~100%. I may not even ever go full on 100%. It's all what they tell me.

Ok so what I’m getting from this is when the leaves are ‘praying’ it could be a good thing or bad thing. If they are up the whole time transpiring and trying to breath, they’ll be tired before your cycle ends and lights go out. But if they don’t go down at the end of the cycle then that’s the perfect light level? Bear with me if I’m way off. I’m more of a hands on learner so it has to be in front of me to understand it. Which is why I stay in my garden examining my leaves under a microscope

No worries. Like I said it's def being debated I've listened to some of the bigger names in the industry discuss praying and what I've learned is that they pray because they are trying to transpire and they can't because of humidity. I'm not saying that's the right answer I'm just saying that's what some studies have shown. If you ever have a chance to check out tad hussey and kiss organics podcast he talks with a lot of scientists that have legitimate testing results and they discuss them.
It's not that If they pray all day they'll droop necessarily, it's more of an indication your dli maybe too high... They drop because they can't handle the amount of light your giving them, maybe due to environmental factors, size or age of the plant, etc etc
What I mean by going down at the end of the cycle is more like if they look wilty in the last few hours then they are likely getting too much light. IF all other factors are considered eg watering etc.
The whole praying thing is kind of a hot topic. I don't want to rub anyone the wrong way and preach that I'm right and nobody else is. I'm just trying to give you some insight on why they may be 'praying' and that it's not necessarily a 'good' thing. And to maybe look at some other factors that could be causing it. It's not necessarily a bad thing either ... They could be photosynthesizing at a maximum level and transpiring alot and the need for air movement causes the leaves to point up. I dunno? It's food for thought. If my plants pray to the sun gods I dim my light and increase airflow. But that's just me.

I know it's kinda confusing. I'm still learning about all these things too. I guess the long of the short of it is your dli is too high so either dim your light, raise it (or both) or change your light cycle.

One of the best investments I've made is getting a scale -like a postal scale or even a bathroom scale. I pack a garden pot with barely-moist potting mix and then I weigh the pot. That gives me my minimal weight. I can't ever allow that pot to go below that weight. Then, I water the pot and allow it to drain. After the dripping stops, I weigh the pot again. That gives me my maximum weight -in other words, that weight is as heavy with water as the mix will hold when it's completely saturated. Different mixes will vary. I add a lot on perlite and vermiculite and rice hulls to the bagged mix so that it drains very well and dries fairly quickly. I grow in 3.5 gallon garden pots. Let's say my minimum weight is 16 pounds....MY particular mix holds about 8 pounds of water when it's saturated. So, after I water, the pot weighs about 24 pounds. All I have to do is to monitor the weight of that pot until it gets back down to the 16 pound range again. That's when I water. And after I water, I know the mix is going to weigh 24 pounds. When the plants are stretching, they might drink 8 pounds of water in a single day! As the cycle slows down, they might not need any water for 2-3 days. But the scale allows you to monitor that progress, either way.

Of course, as the plants get bigger and they establish a strong root system, they become more tolerant of some variance. And when they get really big, they are going to have a weight of their own that must be approximated and compensated for during the grow, too. If your plant weighs ABOUT A POUND, then you need to adjust your minimum weight to 17 pounds instead of 16 pounds.

So a foliar spray? I’m down to try it. I’m open to whatever works lol. I thought about getting liquid seaweed but I didn’t want to mix different nutrient brands. I can rock with a foliar spray since it’s not going in the soil
Yup, will work fine with whatever nutes, like you said use as foliar that's what makes it work better. But cut off when close to flowering.
