BioBudsanswered grow question 3 years ago If your coco/soil has no nutrients of its own, after 14 days use a very mild growfeed, you use Biobizz? Mix a half ml Biobizz for vegetative state in a half liter of water and only poor area around the plant, not the whole pot. But only if your soil has nutrients of its own. Check soil mix, what it says about start nutrients and how many weeks.
