Do you know the reason they look so bad?
1. Because they were flooded every day from day 1 and their roots were rudimentary (about 5-6cm long). For a healthy plant you need strong roots. Medium like coco keeps enough moisture for seedlings if fully saturated before germing. I prefer big pots (7 and 11l) - buffer coco well with root stimulator and supplements, put the seed straight in the coco and 4 days later I have a sprout. I start giving feed/water on day 4-5 with spoon or syringe - just a bit to keep the moisture on the top around the plant. Keeping the medium a bit dry stimulates roots to look for water and nutes and they grow stronger. Roots need oxygen but if you flood them when they are undeveloped, you stunt them. About day 8-9 I start to give them more water (food with every watering) but still don't flood. About day 14-15 they need their first dose of veg nutes and heavy watering.
2. They were grown in cheap coco bricks. Cheap coco bricks have extremely high levels of sodium and fiber quality is very poor. If coco is lighter in colour, that suggests immature fibers. The result is a powdery growing media that has poor structure for root growth and aeration.
You need to flush the hell of those bricks out before use - for a brick that gives you 7l medium you should pour about 10 times more (70l). I first flush with ph-ed water, leave it for 24 to dry out a bit and then fully saturate with feeding solution.
Well, I don't use bricks anymore and get Canna coco - much better.
Just sharing my experience and what works best for me.

Hey there Stone, thank you for your input
Regarding #2, very true about the cheap Coco being shit!
Lucky for me I am no longer using cheap shit Coco and should have enough of this good stuff to last me a while.
Regarding #1, in six days I had visible roots at the drain holes, my containers vary in size a bit but most roots were at least 5 inches long and that is flooding every day with nutes
Also you are using huge (7 & 11L) containers compared to mine, so with way less media I have to water more often.
I have done a lot of reading over the last few days and there seems to be two ways to achieve the same outcome:
1: Flood often with light nutes. (Flood daily)
2: Flood rarely with strong nutes. (Flood once or twice a week)
As this grow progresses watering may change depending on how the plants are going, hopefully green and not yellow.
Also it will be my birthday soon (end of next week) and I have told the family that acceptable gifts are:
BlueLab truncheon
BlueLab PH meter
BlueLab cleaning kit
So that's what I am getting for my birthday even if I have to buy them myself
And thanks Squidy, fullauto and Mandy and everyone else who stops in
