Dude, really? I don't mean to be rude but a bit of reading will solve your issues. See the link in my signature - a beginners guide to growing. Read it all. Too much water and too much food. What are they growing in? If it's Miracle Grow then stop feeding immediately. They also looked stretched which indicates not enough light.

Happy to help but we need more information. Find the troubleshooting link in my signature. Copy and paste to this thread and answer as many questions as you can.
