Actually it looks like they are stretching quite a bit and need light now....personally i put them directly under my t5 full strength as soon as i put them in the soil...basically i let my seed sit in water for a day then i put it in a solo cup with holes in the bottom filled with ffof....i water the shit out of them and then place a sandwich bag over the top and secure it with a rubber band and put them under my light...when they poke out of the soil i take the bag off...that's it...that easy..works almost every time...only time it has not worked for me is with autoflowers and some sativa strains that are sensitive...in this case i soak them then put them in root riot cubes until they sprout and then i transplant them to the cups...long story short..u need to get the light down on them now
