Hi, Got some Primula Candlabra seeds and sowed 25 in a modular seed tray with a peat/pearlite mix (no compost). About 6 have 2 leaves now after 5 weeks, obviously very small with leaves just a couple of millimeters long. I have never sown seeds this small, I dont think I could prick them out at this stage but should I be concerned that they will run out of nutrition? I bought a transplant liquid fertilizer - should I put some of that in a spray bottle and use instead of water until they have more leaves?

Thanks
