pk 13 14

Discussion in 'Advanced Growing Techniques' started by gorrilla, May 1, 2004.

  1. i have been told to add pk 13 14 5 weeks into flowering but on the back of bottle it says to add 3 weeks before harvest
    my problem is that on 1 of my plants there is bud everywhere
    and the other four there is not much at all what should i do
    should i add it to all the plants and count down three weeks to harvest
    or do i add it to the ones that i think are ready
  2. on a 8 week plant 5 weeks into flower and 3 weeks from harvet is the same time.

    if you want to use it in the standard way then add it 5 weeks in as its hard to tell just when the plants will be ready. harvest when you would normaly, amber tric's etc. pk wont change the due date by much if any and its only nutes anyway so letting it longer than 3weeks after use wont do it any harm.
  3. You can give PK 13/14 during the 5th or 6th week of flowering, but only during one week, together with your basic ferts.
    I did a little experiment by giving already minimal amounts of PK 13/14 as soon as the first flowers appeared and the plants liked it!
