We planted sweet pea seeds. They flourished at first but a few are starting to brown and dry out while others in the same pot are flourishing. Theres no apparent bugs/aphids etc so I am guessing its light, water or soil issue. What could be causing this? I've included pics, 2 of the browning seedlings and one of the ones in the same pot that are doing really well, for comparison.

Hi and welcome, Kirsty. Hmm, that's a mysterious problem.

Can you tell us more about what kind of soil you planted them in, and what you've been fertilizing your little plants with? How strong and how often?

My thinking is the most likely cause would be fertilizer burn. Small new plants generally need weaker fertilizer more often than larger lustier plants. So if the smaller plants are browning and looking burnt, they may have had too strong a dose of fert, while the larger plants were big enough or growing fast enough to use the same fert.
