The plants look good and don't look like they really need much of anything but TLC and time. During flowering, plants use more of the P & K, while common wisdom is to decrease the N slightly. If you look at almost any fertilizers designed for flowering, the N will usually be lower than the other 2...during growth stage, the plant uses more N, which is used for building a lot of the general mass of the plant and not the flowers as much.
Depending on your growth medium, you might not need to add too much to them as it can get stored in the dirt/soil. With fertilizer, 20-20-20 (NPK) is considered a general purpose dose that is pretty good for everything. When flowering, the numbers change with more Potassium and Phosphorus used for the flowers.
My biggest disappointment is when I get a bunch of "Whiskers" that shrink to a piece of fuzz when it dries, especially early in flowering! I find that time and light intensity are often shorted by early growers, simply because they are eager to try their crop as well as not using as much light as they should.
Things are looking great...keep up the great job. Each little tweak makes it a little better. Enough little tweaks makes a great big difference! Patience and don't overthink it is the secret, I think.
