I have 2 Autoflower seedlings a week old growing in soil under 300W LED light. Looking at starting Grow nutrients towards the back end of the week. Have bought the Ionic soil grow nutrients, recommended dose 7ml per 1ltr. Should I reduce this for first couple of weeks? Guy in the Hydroponic shop said not to bother but you here so much about leaves burning etc with too strong nutrients in young auto's. Any advice on feeding appreciated guys..
