Will Trichs Mature Once The Plant Has Lost/yellowed All Its Leaves?

Pretty much everyone in my closet has gone full yellow leaves but the trichs are still clear for the most part.  Will watering and letting them keep on mature the trichs further, or will they just stay as is due to a lack of photosynthesis since the plant has no green left in it?  Deciding whether to chop or hang in there.
 
Thanks!
