Hi. A 4" pot seems very small. My chilli plants are 6" tall and I will re-pot them on Wednesday. Mine are Hot Patio Sizzle variety which don't grow tall but if you have jalapeno they grow taller and will need staked. They will go into pots about 8" or 9". I always put my Patio Sizzle outside from end May, but I found the jalapeno I had last year didn't do very well outside so I think they need a greenhouse or really bright windowsill.
I have heard that allowing them to wilt will make the chillis hotter. Good luck with your plant. Mags
