10ml AB to 5litres feckin hell mukka, thats 2ml per litre at that stage its stupidly high.
they dont need feed for 1st week when they break through the coco, only water and root stim ph 5.8.
they once they get little bigger and slightly start to pale go 0.2 EC above your background ec. so for example your tap water is EC 0.4 then start your 1st feed off at 0.6EC including AB.
in easier terms they shudnt be on more than 0.25ml AB to litre at this early stage, Use rhizotonic at 2ml per litre.
you dont need drench coco every when they this young every 2 - 3 days, you want the roots searching. much later on every day will be needed.
Keep temps and RH high at this stage also,
