Lol. I apologize the last thread I was reading, he used soil. Yea coco you will have to add nutes every water. I would definitely start on the low side and see what they can handle. I’m new to this as well but I’m getting things dialed. I was giving my plants to much light, to many nutes, waaaaay to much water. You’ll get it figured out. They don’t look bad at all though. But I do think the crinkled leaves are because they’re holding a bunch of water which isn’t necessarily a bad thing since you’re in coco.
