    New to coco... heard various opinions on it regarding feeding Official line from Advanced Nutrients was to feed with half strength feed then water then half strength feed then water I have also been told to let the pots dry out inbetween waterings I took the weight of the pot filled with dry coco on the bathroom scales Now i have heard from the guys at the hydro store that you should feed coco constantly rather than watering inbetween So lets say for example week 1 of veg the ppm has to be 300ppm Should i say feed 0.5L water 4 times a week for a 20L pot? Will the plant be able to take constant feeding in coco? Do i not need to worry about flushing out inbetween waterings like in soil? I have just been told different things regarding this and wanted some clarification on what people are doing? Also, should you completely saturate the coco to start with before planting your 1st seedling Thanks brothers :)

    I used coco last time and gave nutes with water every day in flowering mode. Hope that helps.

    don't worry. There's plenty of ways you can do it, none is wrong as long as you keep these basic guidelines:

    - flush the coco and charge it with at least a low amount of nutrients, before first use.

    - Always water till runoff, at least 10% - this is most important, especially if you always feed, and even if you don't. The more you feed and the harder the water, the more runoff you need.

    - Flush every now and then with much runoff. Once every 4-8 weeks should be enough if you maintain runoff correctly.

    - Use dry cycles up to the point where the roots have filled the pot. Then you can start watering as much as you like (even multiple times a day for maximum hydroponic efficiency - that's what the guy above was talking about, going hydro. However, I do not find this necessary, unless you're recirculating, and even then - keeping wet at all times is asking for trouble, in my opinion. But I'm not that experienced, only one coco grow).

    - get an EC/TDS meter.

    At the moment i am doing a 300ppm mix of advanced nutrients GMB with the sensi cal added and some roots excellurator I have a 20L (4gallon) pot and i am giving her 2.5L per week so that she dries out 1 feeding a week as she is just very small right now I have found that it takes about a week for the pot to dry out this amount of water as i weighed it dry with bathroom scales beforehand and i am trying to do a dry/wet/dry/wet cycle to encourage good root growth Im just worried as i have heard so many different opinions and i dont want to nute burn her as i have been used to soil before Thanks

    if you happen to notice a burn after feeding, you just have to flush it immediately and then feed it again with a lower amount. The burn will stop at once. You can water when the weight is about 50%, they say. Or a bit less.

    The schedule you asked about above sounds about right (if you're converting at 0.5), but some plants like the highest ppm to be 750, so you have to see for your strain what its limit is, and apply the method from the first paragraph.

    are they seedlings?

    seedlings are the hardest thing to do in coco IMO, if you got that right the rest will be easy.

    see again... many opinions i just want to know: -how many times to feed per week -what volume to feed per week -constant feed or water in between? i can follow the nutrient calculator for everything else Oh yeah, and should i supplement with sensi/cal @ 0.5ml/L (approx 100ppm) all the way through growth and bloom using advanced GMB Thanks

    Ok ash... constantly feed it is... I have a nutrient calculator to follow so that is where i am getting the ppm's from Im just worried about overfeeding/underfeeding my plants and getting the correct amount of water in there Im slowly working it out as i go along Thanks for the responses

    well start off using a little underfeeding is easyer to correct
    start off using just a little in the water n then crank it up when you see how they respond
    just use your head, liltle bitt of commen sense n it be fine

    would you care to elaborate?

    It's actually some pretty flexible guidelines. What didn't you approve of?

    not that i dont approve you laid it down fine

    just the points you made about flushing and these dry cycles
    dont know what coco your talking of but usually if you flush it you wash away all the micro activity, should always have a nutrients in the water just less if you need flush it, and you say keeping wet all the time is asking for trouble im saying the oppersite.

    dont take it the wrong way its just just a discussion
