Looking fine to me Kosher! 
seedlings like the high humidity i feed my girls 500ml of water with 1/4 strength nutes every feed at that age heres my red poison day 9Here it is, day 9, looking hungry i will up the feed next application should be tomorrow.. its been 2 days since the last one.. i wonder if i should pass on using the humid tool so the coco area will be less moist and dry faster?

the only thing im doing different this grow is i am using full strength rhizotonic rooting booster instead of 1/2 strength gave them 1/2 strength the first water then onto full strength and no side effects as of yet so in 1 ltr of water im using 1 ml canna A and 1 ml canna B and 4 ml rhizotonic trying new things as ive always started off slow in cocothanks wile ! lol Well, not so the same! it looks like mine is 3-4 days behind yours. The way your red poision look is the way mine should be aswell right now. so i obviously recognized some problem in growth!.. i guess i will just have to wait and see whats going on..

to be honest blue i just feed them when the coco looks dry on top i also use root riot cubes but being paranoid about a seedling not popping out the cube i pull them apart to put my freshly germed seed in i also water in my coco 2 days before i plant my seed 1 ltr per pot and the same mix asI do exactly the same with the initial nute blend Wile eI've notoriously had slow starts in coco too!
Do you water 500ml for the first water - or build up?
Just out of interest (and to see if i can improve my starts) what's your first week feeding schedule look like?
Day 1, Day 2, day 3, etc (if it's not too much touble) ^_^
