Hey mate,
i will write you a private message. You can check it on bottom right screen.
Your plants look very dry, the big ones are in coco soil, right? You have to water coco soil very often with less water than normal soil. Your plant on the bottom could have pH issues, what pH you use to water your plants? For normal soil you should use 6-7 pH, for cocosoil you should use 5.5-6.5. Overall you have to water them more.
