Burmeseanswered grow question 4 years ago Hi there, If you are growing in Coco, you can start adding Nutrient with ppm about 400~600 for this stage.If soil, don’t need yet.It can burn the seedling.But your diary said your medium is Coco/perlite mixed.So I would like to recommend to continue your current line up for now and start with grow in next week.Happy growing... ✌️
