Lanky Saplings | Vegetable gardening | Hydroponics farming in India

Hi People,

This is my first post on this forum. I need help.

I have managed to grow some saplings of radish, ladies fingers, methi and beetroot. But unfortunately they all are very lanky in their growth. All of them are growing very slowly and also falling on ground. I will try and post pictures of what I am saying soon.

Please suggest as to what am I doing wrong. I am using coco peat and compost as the growing medium and water using a spray and also the sunlight is ample enough as I have placed them on the roof top.

Can someone please tell me of how I can post photos?
