PlantBoi670 You really have some well rooted plants there. They look like Variegatum and if they are they will grow very fast. If you get them into pots now they should take hold and fill out nicely. Don't worry about the yellow leaves, just pitch them and put the rest of the plants into a good potting soil. If you are just beginning, you may find it easier to just buy some Miracle grow and see how they do. Many people mix their own soil, but I have been raising spiders for many years and switched to Miracle Grow as I got older because it was easier and since you should not fertilize these plants for the first three months I find it fits my schedule and methods. Miracle Grow now comes with some fertilizer in it but not enough to do any harm. In fact you may be able to find some without the fertilizer until your plants get older. Good luck and keep us posted.
Here is a shot of my Variegatum and Variegated baby Spiders.
