Purple Leaves - is this bad? (picture)
My seedlings have started turning purple on the underside of their leaves. I've read online that this might be because the room is too cold. They are sitting in a sunny window during the day so maybe I should move them to a warm room during the nights when it gets a bit drafty? Anything else that could be causing this?
hi new gardener
Purple underside of plant leaves generally indicates a phosphorus deficiency which could be from a soil that is too cold , too wet, too dry, for the bacteria that feed the plants to be busy, so plant is not able to get phosphorus or maybe, possibly a general phosphorus deficiency in the soil.
this is common in seedlings when cold, keep warm and just moist and they normally grow ok.
