Weekly PPMs - What Is Your Feeding Schedule?

Discussion in 'Growing Marijuana Indoors' started by waterfarmer, Sep 16, 2009.

  1. I have seen a few suggestions online about weekly feeding, but very few. Here is the one I have mostly been using:

    WEEKLY FEEDING SCHEDULE: (ml per U.S. Gallon)
    Week 1 (rooted clones or 3 leaf-sets on seedlings) : 2.5 ml EACH Grow, Micro & Bloom
    Week 2: 5ml Grow + 2.5ml Micro + 2.5ml Bloom
    Week 3: 10ml Grow + 5ml Micro + 3ml Bloom
    Week 4 until 12/12 : 12ml Grow + 6ml Micro + 3ml Bloom
    Week 1 of 12/12 : 6ml Grow + 6mil Micro+10ml Bloom
    Week 2 of 12/12: 3ml Grow + 7ml Miccro + 12ml Bloom
    Week 3: 3ml Grow + 8ml Micro + 14ml Bloom
    Week 4: 3ml Grow + 8ml Micro + 16ml Bloom
    Week 5: 2..5 Grow + 7ml Micro + 18ml Bloom
    Week 6: NO GROW + 6ml Micro + 20ml Bloom USE UNTIL FLUSH!
    Flush 10-14 days before harvesting

    After limited success experimenting with Lucas Formula, I switched back to this feeding schedule again. But, recently I was looking for alternate suggestions and found only one:

    Week 1 - PPM: 0
    Week 2 - PPM: 0-300
    Week 3 - PPM: 3-500
    Week 4 - PPM: 5-700
    Week 5 - PPM: 7-900
    Week 6 - PPM: 9-1000
    SWITCH TO 12/12 LIGHTING AND BLOOM NUTES (this is just an example you don't have to switch to 12/12 now)
    Week 7 - PPM: 3-400 (note the drop after switching nutrients)
    Week 8 - PPM: 4-500
    Week 9 - PPM: 5-600
    Week 10 - PPM: 6-700
    Week 11 - PPM: 7-800
    Week 12 - PPM: 8-900
    Week 13 - PPM: 9-1000
    Week 14 - PPM: 10-1100

    These two schedules are radically different, as is Lucas from the other two. So this got me thinking. What do my fellow hydro growers shoot for PPM-wise, week to week through veg and flower?

    Thanks,

  2. really it depends on the strain and the water
    i never stick to one strain i should tho.., i always try to grow different ones
    however.. if i was using r/o water

    For my current grow im sticking to something about like this

    Week 1 - PPM: Pure R/o water only
    Week 2 - PPM: 0-300
    Week 3 - PPM: 300-500
    Induced 12/12 @ 15 inches
    Week 4 - PPM: 500-700
    Week 5 - PPM: 700-900
    Week 6 - PPM: 900-1100
    Week 7 - PPM: 1100-1200
    Week 8 - PPM: 1200-1300
    Week 9 - PPM: 1300-1500
    Week10- PPM: Pure R/o water only

    different strokes, for different folks
     

  3. why the drop after switching nutrients? just curious
     
  4. Interesting. Thanks for the input.
     
  5. I don't know. I just found that feeding schedule online as a suggested feeding schedule. The drop doesn't make much sense to me either.
