Nutrient Schedule Question

  1. Hi, first post on the website (hello everyone) but I have been lurking for a few years and generally have found answers without needing to post. But, I've been thinking about manufacturers nutrient schedules lately and have a question. I will start at the begining though.

    I'm growing in coco with a 2.4m x 1.2m x 2m tent. Two MHL 600w bulbs for veg and two HPS 600w HPS bulbs for flowering within air cooled reflectors. Using Canna Coco A+B for base nutrients, RhizoBlast. Cannazyme, Cal/Mag, Epsom Salts, Bud Candy, Big Bud, Diamond Nectar, yadda yadda.

    My question is, when manufacturers say 20ml for week X of growth/bloom do they mean 20ml every watering or 20ml for the week i.e. if you water twice a week add 10ml in the first feed and then 10ml in the second. I water with nutrients everytime so I could be adding to many nutrients or not enough at the right times. I find the manufacturers schedules confusing on this matter.

    Also, during the Bloom phase I have 7 - 8 different nutrients/supplements going into the mix. I always make sure PPM's are within recommended amounts for a particular stage of growth and I cut back on the base nutrients to achieve this. But should I be braking the boosters and supplements into two rounds per week i.e. always add base nutrients and add bloom boosters into week X "feed 1" and then base nutrients and supplements into week X "feed 2"?

    I hope that all makes sense and hopefully someone can give me closure to this question. Thanks in advance.

    Coco should be fed daily with nutes to 20% run off or you will eventually develop salt build up. Your pH should be 5.8 - 6.0. Feeding daily replenishes the nutes and pulls in oxygen to the root zone. Personally I would eliminate most of the expensive additives - waste of money. I don't use any additives - just the basic nutrient and silica blast for strong branches and cell walls.
