Welcome back! So, the hints for the light and earth phases are, if I'm not mistaken (I am using an old design document for reference instead of the actual game, cause it's faster) are as follows:

Light -
You cried for help, it came out wrong, 
In the dark, your light grew strong.

Earth - 
The Triplets heave the baffled sphere, Approach with care, Take heed, Take heed, 
They will not grant you wishes, dear, But may yet give you what you need.
(It is dark here, empty - something wanders in that emptiness, something that frightens me. Be careful)

The earth one is actually pretty literal, even if it sounds a bit cryptic. Find three triplets holding a sphere in a dark, empty place. The phrase is nearby.

The light one might require a bit more interpretation. The couplet is essentially a set of step by step instructions for how to find it.

1. You called for help. 
2. It came out wrong.
3. In the dark, your light grew strong. 

The first two steps lead you to the general location. The last step tells you what to do once you get there. 
As always, thank you for playing! Let me know if that helps. If not, I'd be happy to provide more hints.
