First Grow - Bruce Banner #3

My first grow. It's been a long time coming. This grow is 4 plants, 4 strains in a 90x90x200 with a 440w LED. Bruce Banner #3 Gorilla Zskittles Amnesia Haze Blue Gelato 41 The Banner and Skittles broke the soil successfully this week but unfortunately the Amnesia and Gelato didn't cut the mustard. Successfully germinated on second attempt however this means they are a little behind the the other 2 for now. I have the light dimmed to around 20% as the ladies were showing signs of having too much light, a slight yellowing to the ends of the leaves on the Skittles? This was with the light at around 50%. Will ramp this up slowly over the next couple of week once the other 2 break soil.
