Does flowers looks small for day 20?

I wouldn’t say they are large for day 20, but the plants look healthy, just keep up with what you’re doing. Different strains develop differently so a timeline is not something I would stress over.

The one on the left seems to have closed the leaves a bit. How many lux of light do you think I should provide?

Looks good, I personally now have a goal to make as small flowers possible. People want big buds but I just tossed a pound to botrytus it grows so damn easy. Once infected just spreads like fire. So I wouldnt be trippin!

Not sure about the lux value tough. Mars Fce 3000 distance 45 cm dim 75%.

I think you're ok. Maybe drop the light down a tad bit but keep an eye on it.

She longs for the touch of pollen, her buds reaching out in a delicate dance, as if to find a partner in the wind. But deep down, she knows her purpose—she's crafting a beautiful, healing medicine, her every fiber devoted to nourishing and soothing. She glows in emerald and amber, a silent guardian, giving her all for the gift she’s growing within.looks ok to me? how's it lookin' to you?

Lux is fine for white LED lights. In flower I go between 50k and 60k.
75% at 45cm is about ½ the amount of light recommended by the manufacturer.
Their recommendations are here.
Your plants have a good coloring and the canopy covers all of the available grow space, which is great. If your light levels have been at 50% of optimal throughout the grow, your yield will be modest because there's an almost linear relationship between light levels and crop yield.
Speaking loosely, it's never too late to increase your light levels. At this stage of growth, you might not gain much but providing your plants with more light certainly won't hurt. It's almost impossible to give cannabis too much light. A cannabis grow that's well setup will thrive the light output from that light at 100% and a 12" hang height. Cannabis i
If you chose to increase light levels, I would suggest that you increase the dimmer setting to 100% and set a timer for 30 minutes. After thirty minutes, check your plants to see if any leaves are starting to curl their edges (canoeing or tacoing). Another reaction to too much light is leaves rotating around the petiole, similar to how a Venetian blind opens and closes. At your current light level, increasing the power should not cause that reaction if your grow is in decent shape.
If you do see a reaction from the plants, raise the light a couple of inches and call it a day. I'd be surprised if this was the case because your plants are, I'm guessing, only at 600µmol or so which is about the minimum that cannabis should be given in flower.
Assuming that your plants are handling the higher light levels at 100% power and 40cm, drop your light by 5 cm, check for a reaction, wait a day, and drop another 5 cm. At 30cm± you're probably going to see a reaction. If so, raise the light a bit or turn the dimmer down from 100 to 90% or so and you should be good.
For future grows, a light meter (26 USD) is an inexpensive and proven method of feeding a cannabis grow to get higher yields. Light is the only way that plants make food. Increase the light levels, get more weed.
I created this table from the cited source. Each increase of 50µmol resulted in a yield increase of about 5%.

Sorry for the late reply. I have just seen it man. OK I'll figure it out. Thanks a lot mate!
You're welcome!

Don't blindly follow manufacturers recommendations. Follow the plant response to input. The numbers are targeted towards marketing and higher numbers sell more products.
We can all find and copy numbers on the internet but it won't help or make you or anyone else be a better grower.
If you really want to help post your own data that other growers can compare to other peoples results on the forum. It's getting old with all the copy pasting that doesn't bring anything new to the table IMO.

No idea what this means.
I'm providing the recommended values for the company that makes the product because I thought it would help the poster.
I agree that any one is free to contribute and it people want to chime in, that's great. I spent some time finding the information for the OP and then put together a few paragraphs based on my experience and expertise. And it seems that I'm the only person who is doing so.
If you want to add something, that would be great. You have quite a bit of experience so feel free to chime in.
At times I do but I tend to stay away from doing so unless it's to illustrate a specific point. In this case, I didn't think it was.
"all the copy pasting" - I rarely do copy and paste from other sources. I will cite sources and provide data from those sources but I really don't recall copying a body of text from a web site and pasting it into a posting. And I'd be careful to cite the source.
I do upload research documents that I have read and highlighted when I think it adds to the discussion. While I post a fair amount each posting is written on the fly. Sure, there's data in common between some of my postings but each one starts with a blank text document. That's something that I've considered changing-rather than writing and re-writing, I could put a lot of this in PDF's and just upload that.
Below is a screenshot of my text editor (it's BBEdit, a text editor on the Mac). Those "untitled" documents are some text/a posting that I've composed, some of which I've posted, some I haven't. It's a handy scratch pad.
I tend to stay away from posting results that I've had from particular techniques because those are not "data", they're stories/anecdotes. My preference is to cite research because that's reliable and, hopefully, reproducible. I trust the results of research over the anecdotes and, even though I provide data from my grows, I realize that my grows are "an expirement of one", meaning they're not an expirement, they're just plants growing in an "uncontrolled environment". I did do chem, bio, and physics through the equivalent of US high school (I'm not from the US), but I learned enough to believe that we're not doing "experiments" here, we're just growing weed.
Having said that, I do see that growers are keen to read the results from other growers so I can include photos of my plants as well as data from my grow journals. As the saying goes, a picture is worth a thousand words so I'll try to add more visuals instead of just dry data.
I appreciate the feedback.
