Adopting Eleven Roses week 1 flower

OK week 3 guys the yellowing seems to be going away and I have no idea what caused it😂 One is being watered with only pure watter at 180 ppm and the other I gave a feed 2 days ago and a clean watering today. Both seem to be pulling ahead making nice flowers, stretching up and becoming bushier at the same time. I also did another bit of light defoliation and got rid of unnecessary fan leaves I missed the first time round. I've added photos without the light on for better view of the ladies and the issue I'm having with them. Opinions would be much appreciated as a first time solo grower, I've only watched other people grow so far😁
