Week 1 done. Have gone back to using Vitalink Plant Start for ease of use. 6ml/L and Dutch Pro Callaghan at .5ml/L. The first 3 days are very important to autoflowers. In 40L of Plagron coco I will provide everything g a decent size plant needs,and if you want big yields you need good genetics and big pots - that is it really. Easily grow 300g every month by sticking autos in big 25L+ pots. Simples!
