Jkaris... Peppers heat production (assuming water, exposure to sunlight, nutrients & vigor are equal) is most greatly influenced by weather... The hotter the weather the hotter the pepper. Was that first round produced during a cooler period? Also, there is some truth to hotter next year, because after the first year, the plant is mature and has already developed roots/fruiting structures and therefore can put all of it resources solely into producing fruit, (doesn't have to grow roots and as any leaves/branches). More nutrient & energy input into fruit = Better result.
Also, I just saw your curly leaves post... Hard to tell without being there to inspect. My best guess is PH or great weather changes... Doesn't look like leaf rollers are present, definitely not a nutrient issue, might be rot... Exposé the crown & some roots and take a look... Healthy roots are white... If they are dying back, are brown or have nodes or fungus on them you have root issues (nematodes, root rots, armerillia, etc.). Check out UC IPM (google it), there is a wealth of crop specific info there (pests, disease and care).
PF, A lot if things could be affecting the transplanting. Try direct seeding the lettuce. Plant more seeds than you need and once germinated, then thin (remove) for spacing and leave single plants in the spacing recommended on the seed packed. Harvest before they flower and get bitter. When watering allow some dry down on the soil surface (to prevent rot), but always keep the subsoil moist.
You guys can always PM me with questions anytime. I'm an agricultural consultant and will be happy to help if able.
