Plant Type: Brought home a California Pink Anthurium from a good neighborhood nursery. 1st PROBLEMS: 1. In a few days, brown markings appeared on a few leaves (3-4) with cracks/holes. 2. Three to four light pink flowers started turning green. I gave it a little generic indoor plant food from the nursery. ROOTS: After ten days of acclimation in the new home, I took a look at the roots, and they seemed healthy but very dense and tangled. So I decided to mist in the kitchen sink and repot. The soil was the recommended indoor potting mix from the nursery plus a little more percolite mixed in. METER READING 2 Days Ago: 100 indirect light (just enough light) 8 moisture (too much water) 6.5 Ph (good PH as it just came from nursery) 2nd SET OF PROBLEMS WHEN REPOTTING: As I was repotting, gardeners walked by with leaf blowers on full blast, blowing ragweed on plant and pots! I tried to wipe down dirt and debris. As I was repotting, I thought to cut plant in half to propagate as it seems a little tall and dense, but it wouldn't separate. I repotted the anthurium as one plant, fearing I ruined it by cutting through too much. CURRENT PROBLEM: Today, more of the flowers are turning green. Nearly all are affected. Is my plant on its deathbed? How should I fix the issues with the flowers and the leaves? Thank you!
What is the unit you are using for your light reading? https://www.greenhousemag.com/article/anthurium-tickled-pink/
This website suggests that "when your anthurium flowers turn green, it may be (the) species or it may be age or incorrect cultivation." Hopefully it can help you narrow down the possible reasons why yours are changing from pink to green. It's not unusual for indoor plants in particular to take a few months to adjust to a new environment - often quite different than the optimal conditions they enjoyed in the grower's greenhouse. Once your anthurium settles in to its new home, I wouldn't be surprised if future flowers hold onto their pink colour (unless of course it has been bred to produce green flowers).

A meter from Home Depot. It also measures "water" and "ph balance" in addition to light. Can't think of brand name.
