Help! Leaves started turning black

Growing amnesia haze autoflower, everything has been growing great and healthy until today. I’m at 10 weeks. Does anyone have any idea of what this may be and/or the cause?

It’s been hot here, but did drop to low 60s the last couple of nights…not a drastic drop though as it’s been upper 60s prior (for the lows) I have a second that started together and it doesn’t have this black color in the leaves

Great news…thanks all! I was in a complete panic! This is my first ever grow and have babied these two since their seeds popped, following all the advice I’ve read here on the forum…couldn’t understand what I could’ve done wrong! So so glad to find out it was a false alarm!
