Athosanswered grow question 7 years ago It looks healthy alright. Since you started in half a liter pot, be careful with over watering, that could be a reason for the wavy leaves. I would recommend against feeding so early, unless you are using a really light soil mix, and feed around 0.5 EC (250 PPM). Before feeding, I would pot up to a 2 liter pot, when you notice you have tu water more often, like every 3 or 2 days. By the way if you go ahead and feed, be sure to give 7 to 10 days between each feed
