Is there any optimal way of farming the season materials?

You mean stuff for the tonics? You need to play Onslaught: Salvation

The "blood drive" from the I think Europa (?) Major Fieldwork will give you mats off of enemy kills globally across the game, letting you get hundreds of the green ones from anything.

The blue ones, however, come from seasonal activities. The onslaught: Salvation gives the first two kinds of blue flakes, and now the new Tomb of Elders activity gives the "tomb flakes".

Purple ones just come from activity completions.

No really good way to farm them aside from prioritizing seasonal activities. Keep in mind you have months to get the tonics.
