Looks okay.. these plants are robust and can withstand a good amount of user-error.
Some things i notice:
should use smaller pots for small plants. very difficult to water in a healthy way when you ahve a tiny plant in a big pot. Don't listen to the nonsense that gets repeated ad nauseum that transplants cause shock. First, what we do is better describd as potting up, because no damage is done to the root system, unlike a transplant with an outdoor plant, which is very stressful and does cause shock / recovery time. I've done 300-400 or more 'transplants' potting up and yet to see 1 plant get shocked by it. Don't molest the rootball or tear up a bunch of roots and all is well. Easy to avoid such things with a little care.
Watering in a big pot with a tiny plant - make sure you water all the way down or else you are training superficial roots, which is less than ideal. Also, likely causing dry pockets and uneven distribution of nutrients etc etc.. it's just a bad idea in so many ways with zero benefits. Get comfortable potting up and keeping the pots an apporiate size relative to plant size. You'll develop a way more efficient root system and the benefits from that are measurable.
add more perlite or similar drainage amendment to your substrate in future.
To properly assess the color, reduce light or remove to normal lighting and re-assess. Intense light can make it look paler than it is and may be a healthy lush green in normal lighting. If it progresses paler, that's a good reason to react regardless of that fact.
if it continues to pale, probably need a bit more Nitrogen in your fertilization.
check out cocoforcannabis guides and articles. the least amount of bro-science nonsense you'll find anywhere. if other sites contradict the knowledge from their guides/articles, it's likely total bullshit. plenty of the information applies to both soilless and soil methods, despite the name of the website.
