No feeding a higher nutrient strength on the led sides. 450 ppm on the hid side and 700 ppm on the led side.
I took 12 Identical cuttings, all started in Happy Frog and all started under led.

Even in the solo cups the Happy Frog usually has enough nutrients to get by the first week but these started showing signs 2 day after potting so I fed a light nutrient feed.
