Also, is this kind of fade normal? It all seems to...

Looks like you got some time.. only 10-20% at best of pistils have color. A loupe to check on trichome coloration will be more accurate. It's somethign you have to observe and learn.. then figure out personal preference on harvest window... you want more or less amber? trial and error is only way to know your preference. ~10-20% amber trichomes is generally considered the beginning of a haarvest window.. .some wait for it to be 70% or more amber. (in general, more amber should cause more of a couchlock or sleepy effect) as far as leaves... i see interveinal chlorosis. It could just be senescence, but more so looks like a little light on feed... difficult to say with a 'super soil'. As i look thruogh last few weeks, you haven't fed much, so i'd lean deficiency. May need to feed a bit given current mix you used for substrate. OR, maybe add a top dress at some point during first week or so of flower to reinforce etc etc... needs a bit more for this current length of time of this grow. After reading other question i changed my mind on symtpom... maybe, a sulfur deficiency? but the spots near bottom could also indicate Mg deficiency... the reason i flip-flopped is that it looks to be occuring top-down mostly. I think some Epsom Salt (magnesiu sulfate) would solve this problem. May be a mix of 2 symptoms? do a slurry of soil to make sure it's somewhere near 6.5pH. A slurry shuld stop a bit short of actual pH - whether up or down relative to 7. it only informs a bit... as long as not crazy far off, all is good and it is precise enough to tell you that much. i'm a soilless guy, so it's hard to suggest anything specific. if you stay on this path, you can get to a point where you simply add water throughout grow (maybe, a lil top dress refresher at some point), but takes time and adjustment to find that balance.
