I hope the attached images have posted. I've got two 8/9 day-old seedlings. Both in ph 6.5 soil with no nutes (it's not branded, I got it from my local growshop - btw, I'm in Turkey). They are in a roughly 1m sq grow space under a 400w HPS light running for 24 hrs (they are Moby Dick auto flowers). Temp is 29 deg and as far as I can tell, there's good airflow (exhaust fan and fan in the space). Both seedlings have had exactly the same treatment, but one seems to be going strong, while the other seems to be on death's door... the leaves didn't yellow from the tips, the went from the middle and the edges of the leaves have curled up, almost making a cone out of one of the leaves... what could be the issue?
