Growing - Plants look bad, need help

Hey, I am new to growing and my plants look very upset. I have attached pictures of their defects. Can someone tell me what is wrong with them? I water them every 3 or 4 days; when I notice the soil is dry. I added nutrients to the water that have 10-15-10 and the other is 24-8-16. Which one should I use?

Thanks for your help

Im certainly dont kno much about weed plants, but for a normal plant that size I would water it every 2 days atleast.

i would remove all the dead leaves the leaves that are dieing and the leaves that dont seem to be dong much just slowing down the plant

Give some more info, what kind of soil, how hot is it there, outdoor I assume, your nute feeding strength, Ph, etc. The more info you can give the better the answer you will get. I might flush for the time being until I got a definite answer.
