I'd go with the red. Remember, it is way too early to pick front or back. Read Brent Walston's articles on developing JBP. He is one of the few that talks clearly about bring seedlings and nursery stock up to size and preparing them to become bonsai. Growing your bonsai from seed or seedling. He has 2 articles just about JBP, and many good articles. All the articles are about what needs to be done BEFORE the first bonsai styling. Website

@Adair M is right, move it to a grow box or Anderson flat in spring, or you locally ideal repotting time.
Texas is an ideal area for growing JBP. These should do well for you. I'm in the ''great white north'', so I can not give you good advice on specific timing of treatments. What I do in June, you might do in February (repot) or July (candle removal). So listen to Adair, he has the best info on timing in the southeastern part of USA.
Read about escape branches, One of the branches in the whorl of branches will be your escape branch, one will be your new leader & one will be your first branch. Or not, depending on what you choose to do.
Also, in the photo it is hard to tell, but you seem to have white ''fuzzy'' matter at base of needles, right at or in needle sheaths, and random brown spots along length of some needles. This could be a soft scale insect, the family is Adelgids, and mealy bug is a typical member of the group. It might be the pine needle adelgid. Best insect spray to use would be one that lists Adelgids on the label. If it lists mealy bug it will probably work, but not guarranteed. Read label, then treat, repeat treatment at frequency label rcommends.
Brown spot on needles could also be needle cast, treat with appropriate fungicide also.
Infestation does not look bad now, but if you stress the tree, their population could explode. Treat now to be safe.
If your insect of fungal disease is not listed on the label, it may not work, so read labels and follow label directions.
Caution, I am only looking at a photo, and making a guess, if you are able to bring it to an experienced person for a hands on diagnosis, that would be better than going soley on my comment. Take a close look yourself.
