@Lala3, any nutes formulated for coco from a reputable manufacturer i.e Canna, General Hydroponics, Advanced Nutrients theres a bunch. I would suggest spending a bit of time researching ones you would like to try and also reading up Grow weed easy, a good source of info to get you started. You've got great genetics (Sensi), but thats not enough. Environment is equally important.
I agree with @@Fingers 100%. Grow weed easy is an excellent source. Research it, if the seedling dies, get more info for the next one. Get some tools like ph pen, tds pen, ph up/down, and some nutrients. Amazon sells full beginner box sets of nutrients for almost all those companies that Fingers suggested. Also, get some starter grow plugs. Good luck!
@@Fingers, I'm using coco, I haven't got any nutrients yet i'm planning on ordering some today but don't know which, I don't know ph or how close lights are aaah sorry!
