When to start at half strengh??

So I see most nutes come with some type of schedule....but with that siad what would you consider to be "week 1"????? Obviously you don't wana be giving a tiny little shrub boat loads of nutes cause there so delicate at that stage in life

What nutrients, medium stage of growth etc? Need more data to give any advices. There's to many factors to consider, what medium? amount of light, temps and humidity and stage of growth is necessary to give any advices.

It's like asking how much food do I need when metabolic rate and nutritional requirements is different for every single individual.

Dont follow schedules, follow the plant. When I grow in soil I've never had to go above 0.6 total EC in flower. Feed-->feed-->water is what I do. Cheers!
