HELP! Sick plant, dropping leaves and looks sad

[Baileywatters]

Hey guys.
I’m new to growing, this is my second go at it all. First time worked out really well I had a healthy plant with very little troubles and harvested some fucken good bud. This time is going a little worse. I have four auto seeds from the US and 3 just local strain from where I live in Australia. The US ones where going good but a couple days ago I went down to water and she looks sick. I’ve given her some good food plant and soil improver but am seeing no difference. I’m not sure if they’re in a pot too small for them or not and if that’s the problem or if it’s something else all together. Can anyone pls help me out before it’s too late and I lose them. Thankyou!!

Indoor/Outdoor? What soil are you using? What's the pot size? What are you feeding? How are you watering?

Outdoor growing. Not sure what size pot I’d say like 20L. Water them once every morning before work and have mixed in some basic plant food and nitrosol in the water once a month. They have gotten worse, I’m gonna give cloning a try before they’re too far gone. I’ll post more pictures below if ya got in other ideas so I might be able to save them then anything would help
