Journal of 2 purple survivors

Hello ! This is my first time growing weed and this is the story of 2 seeds which suffered a severe trauma... I decided to go with Purple Queen Auto from RQS to start with. I started with 3 seeds. They germinated witthout any problem using the paper towel method. I planted them around the summer. Regarding the soil, I decided to go with my own soil and a mix of peat, vermiculite and perlite, directly in the ground in my garden. 2 of them started to grow without any problem and were out after 6days The third one didn't make it. They had the sun on them from 12pm until 9/10pm. And the sun was HOT, 33°C on D1... 39°C on D5
