Hi, all of my 8 res are showing improvement, but on half the roots are very snotty looking whilst the others have gone very white and fresh looking. i just suppose they are at different stages of recovery. Top growth on all is still way better though the ones with the better looking roots are showing paler new growth.
i also have noticed quarter inch lumps of what looks like spam tin gelatin on top of the hydroton on a couple of plants, i dont know what it is or where it came from but it isnt atached to the pebbles, just sitting there. weird.
