20$ Budget grow

So my plants were doing real bad about 4 days ago. They looked really bad so i decided to feed them all the nutrients i had laying around and it really did it justice. Within 3 days of feeding my plants happily recovered and drank everything i gave them. Im still working on my weakest plant its been slowly getting better so ill just have to wait.i planted my seeds on 8/12/17 its now been 18 days and i feel like plants are doing well. Im going to get a bigger box just to help them stretch up a little more. Any advice or tips on feeding would be appreciated. As always good vibes 🌱🌞💧
