DWCHCanswered grow question 5 years ago Cloning in flower has a much slower rooting time than in veg, depending on your skill with pruning and deleafing, I've always had the nicest most vigorous clones from tops, and end up withwhat you're looking for.. straight water is best until roots show, then 500 ppm for a week then up to 800 after, if you know the par and ppfd of your light, aim for a 400 par for preveg and 500-600 for veg to close the node spacing, deleafing fans in veg will accomplish the same.
