Firstly, the soil mix looks really dry. Secondly, the cups are way too small to sustain much development. Thirdly, roots will not grow in light, so you need to next time not use clear plastic cups or cover the side of the cups with something to stop light from reaching the soil where the roots are trying to grow. I have found black plastic pots ideal for seedlings : 4-5 inches wide and 5-6 inches deep, round pots, being my favourites. Baby plants like these do not need any feeding just yet, especially in soil. I would wait until they have been transplanted and have at least 5 "nodes" before feeding and only when growth seems to be coming along nicely, and then only with quarter strength fertilizer until 8-10 "nodes" before moving along to half strength fertilizer. There should be enough goodness in any decent soil to support growth for the first 2-4 weeks, depending on container size. If you can keep them around 24 degrees Celsius, they will be happy. Remember, it is far easier to remedy a slight under feeding than it is to rescue a plant that has been over fed and burnt. At this stage, I would suggest carefully transplanting them into larger pots with soil that has less big bits of bark or sticks in it. The bark and sticks will just cause a nitrogen draw down as they are being broken down by your soils microbes. Either pick the bark and sticks out by hand or you can also use a sieve to get more fine material to add to your soil mix. Make sure when you water them that water comes out the bottom of your containers, the roots can be surprisingly long, even on baby plants. For an idea of how long, look at my diary "Holy Mackerel" to see the root system on a 3 week old seedling and this may give you an idea as to why deep watering and bigger pots are needed. For an easy boost to your seedlings, a dose of half strength (liquid) seaweed extract will help them and the soil they are in. It is more of a "tonic" and not a fertilizer and will not burn your plants. You can either give it to them before transplanting or use it to water them in once transplanted or even both; before and after transplanting. If giving before transplanting, give it to them 2 hours or so before transplanting to make sure the seedlings have had a chance to absorb some. Seaweed is also good to use before any extra cold or extra hot days as it will "fortify" your plants cells and also as a soil stimulant, every 3 weeks or so. Generally, seaweed extract will also contain good amounts of humic and fulvic acids, both are excellent for soil and plant health and it also has true benefit to your soils vitality, rather than the questionable benefit of adding molasses, which I personally think has no scientific proof as to its usefulness. Hope this helps,..... Organoman.

I feel like those are apple sauce containers... Cut holes in the bottom of your containers for drainage.. Your light might be too close.. If any nutrients use them very very light. Are you growing in soil? if so drainage might be your biggest issue.
