Royal Queen Seeds recommends 65-70% Relative Room Humidity (RRH) for the first week, which is about on par with what they all recommend because the seedling has no roots, so it transpires (breathes) mostly through the leaves instead. 65-70% is optimal to do that; more and the leaves "sweat" just as humans do, and it is similarly stressing the plant as you go above 70% in week 1; less and it doesn't get enough of one of the things it needs for photosynthesis: water as humidity that low this early is also stressful. Humidity is one of the easiest things though, and also fundamental: get it wrong and you will see the effects on the plant as it grows both in appearance and yield. With my first grow, I got it wrong too far the other way because I thought my hydrogometer was faulty and didn't put it in the tent (though I did recoord the values from outside the tent and I wound up with two hydrometers, 1 in and 1 next to me, and I could retroactively work out how high the humidity really had been the first three weeks (too high, though I don't think it ultimately affected my yield as I got on top of by week 3). Then you progress downward about 5% a week, aiming for 55-60% through veg and into early flower. where you begin lowering it again by about 5% a week aiming for 40-50% by mid flower and as low as 30% in the last week (by decreasing slowly week by week). Though without even a cheap humidifier and dehumidifier combo this can require more work to try and get close to. When I began, I started (and still have) a very modest setup: a tiny tent, a 150 W LED, etc, but I got good results my first grow despite the inevitable mistakes. Other than that, your start is good.

I've seen a lot of new growers run into problems growing in buckets like yours because they neglect to add the drainage they need, which if you don't add yourself, will create problems fairly soon as water, because it can't drain through, creates pockets of stagnant water below the soil. This leads to different root issues (not uptaking water nutes right, possible nute lockout from salt build up, mold, etc) and you can even get mold below the soil in the roots themselves. Fabric pots plus some perlite in the soil solve this and prevent the plant becoming root bound and they're cheap: about $3 for a 2 or 3 gallon pot that you can wash after each grow and reuse. Though its not worth transplanting again this late I don't think. If you drilled holes in the bucket for drainage and neglected to mention that, then you've covered that so you're good there but if not you need to do it and sooner is better. Though its late to drill with the plant in the soil: I wouldn't want to use anything that create plastic bucket shavings that go into the soil, so instead I'd punch some small holes as close to the bottom as possible: enough and larger enough to allow water to leave the bottom of the bucket instead of becoming stagnant there, but not so many or so big that they allow the soil to fall through (maybe a little bigger than the size of a ballpoint pen for each hole and at least 8 of them around the bottom of the bucket spaced apart). With regards to growth: that could be because the light isn't close enough and this is a tough needle to thread as you want the light as close to the plant as you can get it, but without burning the leaves (which usually can't be noticed until its already close enough to bleach or stress them). Though looking at the heights that other growers with the same light are using as they correspond to your plant's stage can be one method to narrow it down (the other is to determine PPFD output from the light and adjust accordingly: most LED brands publish this as a chart that gives PPFD/PAR at different heights.

Your early problems look directly tied to the low humidity. You've solved that part for this and future grows so really, there's not much to be done from any stunting that results there and that's par for the course: I think the first grow is more to become familiar with the process and the benefits of the journal is you can combine what you observed the first time with notes and photos so your second grow is more dialed in. That's what I'm trying to do this grow. Also, even when it looks bad, keep going as any grow that finishes is a success because of what it taught you. There were weeks late in my first grow where I was really worried that my grow would be among the single digit gram yielders because it had so many nutrient deficiencies on top of newbie mistakes; but I got 30 grams off it so it wound up over-delivering despite the mistakes. You're identifying and correcting issues as you find them which is a huge part of this first time around (and documenting it as well).
