First Grow / Grow #1

Hello everyone, I'm sorry that I haven't updated this diary, I've been on holiday. While I was on holiday my mum watered the flowers with normal tap water. Normally I would be very careful about the pH and the fertiliser, but I couldn't get my mum to keep an eye on these things. Now that I am back I was surprised how much they have grown in two weeks. But two of them have started to get yellow leaves. And I'm not sure if it's because they haven't had enough water or if there's a lack of nutrients. And one of the plants has little pods and they don't look like male pods but I'm not quite sure.
