Where Do I Get GSM Mats?

Hey guys, a fresh 50 GSM here!
So far, I have almost all my HQ AF/normal gear equipped (apart from a few which are NQ until I can buy/make them HQ). GSM is my only DoH class at 50 so far, I'm currently deciding which to do next and think it'll probably be Carpentry cause I'm levelling my alt class which is a BRD. I have an i92 BLM too so I'm no stranger to dungeons.
My question is, where do I get all the materials other than the Market Board? Materials are expensive on Zodiark and I'm poor at the minute. Rose Gold materials, Peacock Ore, everything! I've no clue where to find these high level creating materials from...

You need level 50 miner. Rest is got by trading company seals and myth tomes.

L50 miner can get gold ore in that cave in eastern thanalan where you did the BLM questline. Only appears at 9am in game time and fades at around 11:30 am in-game time

Astral rocks are also mined by L50 miner. There's a cliff near the observatory in Coerthas Highlands that they spawn at. Only appear at 9 pm in game time

The wind and fire clusters are L50 miner or botanist. The miner ones appear at 1pm, 5pm, and 9pm in Mor Dhona (near the road between revenant's toll and st. coinachs find). Botanist ones also appear in Mor Dhona but couldn't tell you where since I don't have botanist.

You make rose gold nugget from 3x gold ore and 1x copper ore.

Astral eye you make from astral rocks

Peacock ore you trade company seals at the quartermaster for (along with the aqueous whetstone used to make the astrolabe I think it is). It's 2500 seals for each, and 9 peacocks + 2 rose gold nuggets to make a rose gold bar.

Alternative sources for peacocks include running expert level dungeons (random chance of getting a peacock out of boss chests, only one and it gets rolled on) as well as doing peisteskin treasure maps (again, small chance of getting ores from the chest, randomly goes to a person rather than being rolled so you might not get them if they drop)

Darksteel nuggets are made by blacksmith/armorsmith, hard hippogryph leather by leatherworkers.

Native gold for making gold bars is a 2 star mining node in central thanalan. Takes a highly kitted out L50 miner to get them (more than I've cared to invest so haven't bothered to get them)

Raziqsand for the gold bar is bought using myth tomes in revenant's toll.

Terminus Putty is made by alchemists using tawny latex (bought using myth tomes in Revenants)

So, I should probably drop carpentry for now then and start miner and level my botanist first for the shards and ore?
I noticed the Peacock Ore when I was having a look at what other stuff they do as I usually just buy ventures from there.
Guess it's back to grinding (and buying the fourth retainer for even more mats) as I used nearly all my Leves on my GSM since it took quite a few cause I couldn't always make HQ items for the bonus XP. Least now I have an idea of what to do next, thanks :)
