Alright so this is my first grow and one of my plants is only three weeks old and doesn't seem to be gaining any height what so ever but is growing very wide and leafy ... going to attach a picture if anyone could please take a look and tell me if something is wrong or whats going on ... thanks.
I have a couple seedlings almost 4 weeks, and they aren't much bigger. Don't worry, some plants are just smaller than others. Kush is an example of one strain that grows short and bushy. As El-Gato suggested, just give it some time. If you plan to feed it nutrients, you could probably start with a half dose on your next watering.
