    I just started 2 seedlings in coco coir, i ordered General Organics nutrients but they were back ordered and will take about 2 weeks to get to me. I know with soil you dont feed for the first weeks, is it the same with coco or would i need to find some temporary nutrients to get me thru the first 2 weeks?

    What type of coco?

    Id feed from the beginning.

    Yep, you'll need some nutes right away. Straight coco has no food in it that you didn't put there. Any full spectrum nutrient will do...Since they've JUST been planted, I'd dilute the nutrient by about 25%, feed, observe, and adjust accordingly, to avoid any possible nute burn. If it's not impractical, I'd also add a little B vitamin to the water for the first few waterings, to help cushion the shock of transplant.

    You need to feed from the beginning with coco.

    I'd use Sensi from Advanced Nutrients. That works for me everytime.

    good luck!

    Its not really about percentages that does not tell you anything about the water that they are actually drinking from. It is all about PPM's. I use Cocoa Core and Perlite 50/50 Mix. Started feeding the day I put them in but I watered from the top and my PPM's started at 350. That was I ppm'd my rez to 100PPM with Cal/Mag and then added nutes. If it was to high I took water out and added fresh water from my Reverse Osmosis. TO bad I cant upload a Video of mine at 8 days old. But seedlings about 250ppm-350ppm depending on strain. Also make sure to PH at 6.0 in Cocoa core. That works the best with that mix. Check out some pics from when i started out at about 3-4 days old and some from a few weeks into flowering.

    Thanks for the info guys, i still have not gotten my coco nutrients but i am feeding her a 10-10-10 1/4 strength dilution of some liquid fertilizer,+ a molasses tea with some mycorrhizae. Im hope this will keep them happy till i get my GO.

    Actually regardless of medium, plants have all the energy they need for the first 2 weeks (sometimes more). Besides tap water (290 ppm) I don't feed any nutes for the first 2 weeks or until I see the first sign of yellowing.

    Coco doesn't have nutes in it, but ph 6 tap water should be all you need for the first 2 weeks. Before then, its very easy to over nute, and at 2 weeks I start with just grow nutes and tap water, working my way up to using cal mag and that's it. 1x a week I use liquid karma.

    Hi guys im in the same situation as bob. My seedlings are 2weeks old they look just fine only gave them tap water until now. I have the general hydroponics flora bloom/micro/gro trio and calmag. I was wondering if i should start all 4 of those at the recommended dose for seedling right now or start with less then go up. Thanks

    Don't feed them for 2 weeks until you see the true leafs come out because it has all ready nutrients in the seeding it self

    You can use the Lucas Formula With GH Flora series except you don't use the Flora grow. The Flora micro has enough nitrogen in it to handle vegitation. Lucas Formula is 8ml Micro 16ml Bloom start to finish if your running autos I would start at 4ml Micro 8ml Bloom .....

    I now this might be a old thread. But I am growing 2 autos in coco. I have GH nutes, so at what week would I start feeding 4/8?

    Johnnygrows420 Well-Known Member

    This is my first grow with coco and autos but yeah it's dialed in....I use GH Flora Nova Bloom GH Cal-Mag AN Bud Candy and the first 2 weeks GH Rapid Start. ....Lowlife Auto Hindu Kush 20160302_211638.jpg

    I'm on my 3rd attempt on coco. Fail, fain and probably fail again. How much should I let the coco dry? First day I feed 500 ml... Sensi Voodoo B52. I'm feeling I overwaterd it every time.
