Thin stem slow growth and color is yellow

If you are growing outdoor temperatures might be to low for the plant... Where i am from we are still experiencing temperatures below 0C during night and your plant would probably not do well under such circumstances. if you are in a somewhat colder climate i suggest keeping your plant indoor during night time..

Hi , he problem here is not nutrient deficiency she is yet to small for that. The problem is the soil is very clayish from the looks of it and the plants don't like it because it holds water very well but it will drowns the roots leading to lots of problems. Let the soil dry out completly and only lighly water the soil don't drown it.

just a few tips mate try not to leave the soil too wet as that stem has the potential to rot the soil should have enough nutritional value in it yeah??
