Just wanted to say yes the girls look unhappy. But in my eyes I don't see over under abondance of vitamins or minerals. So start like the gentleman are expressing. Sometimes it may appear your plants are watered. I reality deep inside it dry. Sometimes if possible and your not sure. Feel the weight. Still not sure if you're scared to drown your girl use a same sized pot with your dirt and soak it fully. I mean waterlogged. To understand the weight aspect. The only thing other I may say room conditions. Possibilities to cool, too hot. Small but environment conditions. So many things whether big or small begin with easily fixed issues. Read them, feel them, talk to them. No one person can give you that intimacy. Don't give up and if this round doesn't work. It's not failure, it's more knowledge. Love and happiness
