hey guys, this is my first grow so I really wouldnt know where to start when it comes to nutes. I am growing 5 easy ryder (lowryderXak47) fem from seed. they all germinated fine and sprouted 3 days ago. they are a couple inches tall and are almost opening up their first set of leaves. I was recommended a product called nitrosol (liquid blood and bone) when I went to the garden centre so I got some. has anyone else used this? my main question is how long until I should start using the nitrosol and how much / how often do I use it? my babies are currently in party cups until they are big enough to be transfered outside. cheers guys
