main thing i would say is the timing of watering and the way you pot up. i like to use a small of a pot as possible each time, never giving it too much unrooted space. when first planting, using plain distilled water in a VERY small area where you KNOW the roots lie, and letting it drink all of it before watering again but never to the point where it wilts. gradually increase the amount of water you give it. try to imagine teasing the roots down into the soil. when it comes time for a new pot, i really do let it become rootbound, and the new pot is only big enough to add a small extra wall of soil, never more than it can handle rooting. i swear this whole dynamic is crucial.
after a few weeks of that i start to introduce nutrients into the distilled water, pH at around 6. generally somewhat low doses of cannabis growing nutrients, like cal-mag or a 2 part base. just something to give the distilled water a little reinforcement. i use humboldts secret base a+b. once you can tell the nutrients are not harming it you can use them just about every time, and that’s probably what made mine huge, along with 18 hours of light. these GE bulbs at a couple feet distance gave me the best results.

I used only the strips overhead until a couple weeks ago, and now I have that “ballast” overhead and the 4 strips on the walls in a square. Coming from growing high powered and high yield cannabis years back, these things are comically cheap, but with salvia we don’t need an inferno, so they are actually ideal. The weed on the other hand.... I’ve never seen it grow so slow, but that’s not my focus it’s just kind of there.
This is smart 🤔 I may adopt this for water rooting clippings! Have you tried an aeroponic cloning machine? It hangs the cuttings in an empty reservoir constantly misting them with water and hormones or nutrient solution. The misting manifold gives my reservoir the perfect, gentle heat boost too and the results are amazing for some that are difficult to root or won’t in straight water! My bucket holds up to 36 cuttings at once. I’ll attach a link to the one I bought Amazon-Clone King 36 Site Machine
My current outdoor weather registers 45% humidity. I run the AC all the time in summer (which saps moisture out of the air). In the winter it can feel incredibly dry so I have to run humidifiers to counteract it. I have not seen any evidence that high levels of humidity are necessary as the plant seems really adaptable to different environments (though the plant does lose leaves when there is a change in its relative environment so if you were to make an alteration it will, with time, eventually lose leaves as it grows new ones that are adapted). What I HAVE seen is lots of people kill their plant with humidity domes and root rot.
As for the light, I guess it's fine - I also don't think anything fancy is needed. Currently using this: https://www.amazon.com/gp/product/B08HD25RHR/ but I've also used just a plain old 60w LED light bulb in a desk lamp. You definitely want the light to be relatively close or else the plant will get leggy (lots of stem with fewer leaves), and that seems to be the case with your plant.
Here is currently how I have mine growing just to show you: https://i.imgur.com/mvytdcl.jpg Personally I'd say mine are growing pretty vigorously.
DLI is very simple actually - imagine your plant is a bucket, and the DLI is the daily amount of water you supply it. Every plant is a different size bucket, like a cactus is huge, and a shade loving houseplant like salvia is fairly small. If you give it more light than it can absorb in a day, it starts to experience light stress. But if you know exactly how much light you can give it, you can maximize its growth potential. here’s all you gotta know practically speaking:
Get a light meter (that app is great because otherwise light meters are hundreds of dollars) I recommend the Photone app
Use any decent plant light (I like Maxsisun MF1000, it’s way more than salvia needs, but you can dim it down or raise it higher and cover a large area potentially with a single light and it’s very cheap, giving you options)
Adjust the height/intensity/timer for your light such that you’re giving it at least 12 hours of light, and a DLI reading of around 12. This will maximize the metabolism of your plant and be automatic forever
On separate outlets, I run one satellite dish heater and one infrared heater. Both are controlled with InkbirdSmart 308 temperature control.

I use this sensor which logs the temp and humidity data and connects via Bluetooth to transfer it to your phone: https://www.amazon.com/dp/B087313N8F/ref=cm_sw_r_apan_glt_fabc_3G48NXR7BRF2F8A9Q5ZP?_encoding=UTF8&psc=1
It requires an additional app, but I've been happy with it. No intrusive ads or anything. There's also a wifi version for just a few dollars more that I wish I had gotten. The Bluetooth range is about 20-30 feet, I've found. You can see my recent post with a screenshot of the graph showing the data for a particular time period.

u/zentheogent, you had moved your plant across the room. Are you concerned about your light being too intense? I use led with 5 intensity settings. I keep it set on mid setting and in a window. Here is what I use:

I use a college desk lamp I bought at wal mart or something for the daylite bulb, which you will want one of. I got mine at Lowe's. I think it's a 5550k CFL, it was like ten bucks.
These are the clip wand lights I bought, and I also bought a set of these which are super versatile and have pretty good coverage.
