Autoflowers Cold Growth

I planted some autoflowering strains 2 weeks ago, I just planted the seeds right into the ground on a creek bank. It has been pretty cold recently but reaches 60° During the day and never below 35° during the night. They are only at the 4 beginning single fingered leaves and some are darker green leaves then I’m used to. My question is, is this normal?

Normal for plants barely hanging on to life. Temps under 60 are a problem, specially under 50 or 40 at nights, will slow down growth and cause deficiencies as the plant can’t uptake certain nutrients at cold temps. Hope it warms up for your plants.
