It happened to the small one then the meadum one then the big one. i had bin putting cal/mag in 40ml for 12 gallons. This is outside should I put more in? Or is this somthing else?

  3. I've bin adding some kelp and it's a thick brown. I dug up the small one hers a pic image.jpg

    It looks to me like root disease is causing the deficiencies. Sorry to say...

    I use cali magic at 4ml/gal. You shouldn't have to add more - it's there, they just can't get it. More won't fix it - also indoor/outdoor you mix ca/mg the same.
  7. Rez change yesterday added more cal mag and the new growth is looking a lot better then The new growth in these pictures. Also these damaged leave haven't gotten any worse. Since the change.
