Not at all, they look healthy and standard. The 2-4 weeks thing is dependent on a few factors; the size of the plant, the strain (if it's a heavy feeder or not), and what you're top dressing with. Those Dr Earth mixes are usually pretty light and won't burn like Blood Meal or Guano will. Wait at least another 4-6 weeks until you top dress again. This is because you've already amended the soil, and because the plants are only seedlings right now. Once your plants are over 1ft tall you can top dress again, at that point simple evaluate your plant and listen to what it's telling you.
What I personally do is start my clones/seedlings in a simple mix of peat, perlite, and compost. Only amendments I use at that time are kelp and neem meals, and something for minerals (Basalt, Glacial Rock Dust, or Azomite if nothing else is available). Once the plants get to be over 1ft tall, I top dress them with a Dr. Earth mix and cover that with compost. I like Dr Earth LIFE for veg (5-5-5) and Dr Earth Tomato and Herb for flower (4-6-5). I'm finally making my own compost, but when I don't have my own compost I buy a bag of Coast of Maine's Lobster Compost on Amazon. During veg, I top dress every 3-4 weeks on average with my Dr Earth, Neem, and Kelp Meals, then cover it all with compost. During flower, I top dress every 2-3 weeks with the same stuff.. just Dr Earth Tomato and Herb instead of LIFE.
It isn't just plant size that will be dictating the amount of feedings, it's all strain dependent. Some strains are heavy feeders and can be pushed hard and fed every 1-2 weeks. Other strains will get pissy at you for over-feeding. Fortunately, you're using amendments that aren't hot so you likely won't run into many issues with over-feeding. It's only because the plants are still seedlings that you're experiencing this. Seriously, just keep doing what you're doing and you'll be golden once they get over 1ft tall my man.
The back of the bags should have some detailed instructions on how much to apply for the size of the plant or pot. For example, it'll say something like 1/4c per 1ft of plant height, or 1/4c per 5g soil, or something like that. It will then tell you how often to apply, usually every 2-4 weeks.
Sorry to be long winded, it's a weakness of mine, but I just prefer to explain what I'm saying to people rather than just saying something and providing no information.
