That second picture looks like a fuzzy egg, with leaves. Its pretty cool :thumbsup: .

Doing nutes you can either do it every time you water with a low strength dose, or every few times with a more powerfull dose. I like to use the second method, because it seems like i can flush the soil a lot more this way.

Someone already said the npk ratios, general hydro seems to be a cheap effective nute line. And fox farm if you want organic.
