reef- To me, seeds are just too vigorous for their own good sometimes, esp indoors. They try to outgrow themselves and can often lead to a wide variety of feeding problems. Clones are a bit more settled. You can even get a clone from your friend, and your 2nd run of that will be better. Plants just need to get used to their environment/food/medium. They should be dialed in in about 100 days of inception.
