Query: So disappointed

I followed the Mel's Mix recipe to the letter, and couldn't be more disappointed. Everything we planted is yellow and spindly, if it is growing at all. I wish I would have paid more attention to the negative reviews on here. I was looking forward to seeing if Mel's easy and inexpensive trellis was really going to be able to hold up my pumpkins and watermelons, but sadly I don't think the plants are going to make it. All that driving to get ingredients and all that work... what a disappointment.
