Im running a hydroponic with rockwool and hydroton and i have a seed and it sprouted yesterday but today the shell came off...i have Advance Nutrients 2-1-6 and it says to use 1.0ml/litre for seedlings/cuttings and i have it all mixed up in a 25 gallon pail with the ph at 5.62...just wondering when i should start to give it that mix from just ph water...

wait at least a couple days to make sure the third tiny set of leaves are starting way down in the middle
