Coco feeding when to start

Well you can't get any better nutrients than Advanced except their PH Perfect Coco specific,no more messing about with PH Pens.You may need some Calcium due to coco holding onto nutrients like calcium.That's why they do a Coco version.Check their website.Advanced cal mag also has extra iron and amino acids in it so it can't be beaten.You will need some.Their feed is 4ml to 1ltr so I give the seedlings 1ml to 1ltr from day 1 then 1wk later 2ml to 1ltr until you see the first true leaves then give full feed.Not sure about B52,its one thing Iv never used as it doesn't do a lot,its just B vitamins.It certainly wants full strength food now.Watch how much more colour it has in 7 days.You should go organic with their Iguana Juice.
