Girl Scout Cookies grow issues

From a fellow grower: They germinated fine but when they sprouted. 2 had the first set of leaves then died. Am I doing something wrong? The temp is 75 and rh is at 70%.

We’re these seedlings in nutes? You don’t need to add nutes for a couple of weeks.

I think you burned week.

Was coco buffered? PPMs going in? My experience in coco says if PH was 6.0 coming out, it was probably high going in! Need a pic of plant! 500 PPMs is high unless a well established plant or clone! T5 light…how many watts?
