  8. NO! Dont back off the watering mate. 2l every 2 days isnt even nearly enough for a 20l pot of coco. You should be feeding to run off every day at least once. Twice is better.
    Coco is hydroponics not soil.
    The more volume you give it the better.
    The problems soil growers get from wet pots is actually caused by a lack of oxygen.
    Cant over water coco. Youll get plenty grief from drying it out though.
    Check the ppm and ph of your nutes and run some through the pot.
    Collect the first run off and check the ph and the ppm of that.
    Then you should see why the dry cycle is a bad idea.

  12. Nah just up the daily volume mate and itll sort itself out :)
    Shouldnt really flush coco unless its a fair fuck up. Just unbalances things.
    If ever in doubt go for a few days on half strength and it should clear up any related issues.
    Ph 5.7 for veg, 6.3ish for bloom.
    500ppm (1e/c) is generally about the right strength. A little more for bigger plants.
    They dont need much to keep them happy like :)
    How many plants ypu got there anyway, hard to tell.

  15. That could be a ph problem also. If you water them and they are still dropping then I would investigate the ph

  20. check your run-off

    if you've been underwatering/underfeeding up to this point and letting it dry out, your run-off ppm is probably over 3000

    if thats the case, you'll need to flush it out a bit with calmaged h2o and get those numbers down.

    might i suggest some light reading...
