zero gold on my account
so with those formula no gold = no extra gold 
but 
Peeps from Kachang can make 2 * gold nugget without having gold ^.^
But it takes a LOT of potions (pots) 
1)
6 * Misou( = 5 * orange pots + 5 * purple pots)
// If you can use 6 * Fertilizam( = 7 green pots / 1 purple pots)
//it would be faster thx to easy green pots
creates 28 leafs (the more leafs you collect yourself the lesser you need to do the Misou mix)
2)
3 * choco lift( = 2 yellow pots + 2 purple pots + 6 leafs)
creates 9 crisps
lefties 10 leafs
3)
2 * faky ( = 1 yellow pots + 1 orange pots + 7 purple pots + 1 crisp )
creates 2 blue crystal
lefties 7 crisps
4)
1 * Lunarizam ( = 7 crisp + 1 blue crystal)
creates 2 shiny crystal
5)
1 * gold transmutation ( = 2 green pots + 2 yellow pots + 2 orange pots + 2 purple pots + 1 blue crystal + 1 shiny cristal )
creates 1 gold nugget
lefties 1 shiny crystal
6)
1 * choco lift( = 2 yellow pots + 2 purple pots + 6 leafs)
creates 3 crisps
lefties 4 leafs
7)
1 * faky ( = 1 yellow pots + 1 orange pots + 7 purple pots + 1 crisp )
creates 1 blue crystal
lefties 2 crisps
1 * gold transmutation ( = 2 green pots + 2 yellow pots + 2 orange pots + 2 purple pots + 1 blue crystal + 1 shiny cristal )
creates 1 gold nugget
= You have 2 gold nuggets + 2 crisps + 4 leafs at the end
POTS NEEDED at the start (only when you don't have leafs and you use Misou):
Green potion * 4
yellow potion * 12
orange potion * 37
Purple potion * 50
POTS Needed at the start (only when you don't have leafs and you use Fertilizam )
Green potion * 46
Yellow potion * 12
orange potion * 7
Purple potion * 26
People from audipint have an even beter skill then gold transmutation
They don't need to do the Lunarizam mix.
Just 2 times Choco Lift
and 5 times Faky
And then Aurizam
it cost more purple potions though (thx to Faky Mix) but lesser from the others.
And from the moment you have 3 gold nuggets go over to the one from ptico
