>>1081383Can you post pics of your setup?
I'd remove the water reservoir or whatever it is. A lot of plants don't like sitting in water.
Check how compacted your soil gets, how well it drains and retains moisture. "Potting soil" can be really shitty depending on what kind you buy.
Are your plants getting enough light? Too much light?
Growing plants is kind of like starting a fire. Fires need the right mix of fuel, oxygen, and ignition. Plants need adequate soil, water, and light.
Just look up the requirements for what your plants need. A simple checklist should contain:
Well draining soil or Dense soil?
Acidic soil or Basic soil?
Let the soil dry in between watering or Never let it dry?
Full sun or Partial sun or Full shade?
If you don't fit the criteria do a search on what you can change to fix that, or plant something else that fits what you have.
That being said, growing plants is never an exact science. You're gonna mess up and kill stuff, but thats part of the learning process. You'll get a 'feel' for what a plant needs, responds to, and what action to take next. Just keep trying new things and you'll keep learning.
tl;dr try new things, get out there and make some mud
