  Why is the compost green? Are you overwatering them? Have the nutrients been washed out of the compost?

  I haven't fertilized the compost.  I don't think I'm overwatering?

  They are looking a bit lanky. Do they need more light? Green growing on the surface of the soil might mean that the soil is soggy - needing better drainage, perhaps... ?

  Ah … plants need a period of darkness as well as light. Give them 8 hours darkness each night.

  The post I am copying and pasting has a lot of useful information, a couple of which I mentioned before, but it has been flagged. There is no advertisement in it except, maybe, in the title of the poster, so I am repeating it in case it's flagged away.
  
  

  Plants can turn yellow for several reasons, and it's important to diagnose the problem accurately to provide the appropriate care. Here are some common reasons why plants turn yellow:

  1. Over-watering or under-watering: Both over-watering and under-watering can stress plants and lead to yellowing leaves. Check the soil moisture level and adjust your watering schedule accordingly.

  2. Nutrient deficiencies: Yellowing leaves can be a sign of nutrient deficiencies, such as nitrogen, iron, magnesium, or potassium. 

  3. Poor soil drainage: If the soil doesn't drain properly, the roots can become waterlogged, leading to root rot and yellowing leaves. 

  4. Pests and diseases: Insects like aphids, spider mites, and whiteflies can damage plants and cause yellowing leaves. Diseases such as fungal infections can also affect plant health.

  5. Environmental stress: Changes in temperature, humidity, light levels, or exposure to drafts can stress plants and cause leaves to turn yellow. 

  6. Transplant shock: If you recently repotted or transplanted your plant, it may experience transplant shock, leading to yellowing leaves. 

  7. Natural aging: It's normal for older leaves to turn yellow and eventually fall off as part of the plant's natural growth cycle. If only the older leaves are turning yellow, it may not be a cause for concern.

  To determine the exact cause of yellowing leaves, examine your plant closely and consider factors such as watering habits, soil quality, environmental conditions, and signs of pests or diseases.
