I used a combination. They both did just fine. As JDU said it's about quality. Some people throw bat shit in the soil. Some add egg shells. Some use pellets. Some use powder. Some use liquid. In the end, we are only going for a good and balanced uptake. I will say that powder and liquid nutrients are readily available after dissolving, while egg shells and organic matter need to be broken down by good bacteria and such.
You want a good N value for veg, and lighter P-K values as well, but don't knock the P-K. It plays a vital role in veg too.
For flower you want 0 N value (after the flower stretch) or at least nothing higher than 1-2. Flowering is where you want you P-K value to increase substantially.
If you are going to use powder, use half dosages and don't look at a 1/4 teaspoon as nothing. For roots that's like smashing 6 Red Bulls at once.
And always pH your water after your nutrients completely dissolve. That's all for now. Cheers!
