ZiG, if you're just in the rooting stage, spraying the clones with plain water should be ok (or so I've read -- I'm no expert). Before they root, you shouldn't give them any nutes.

As for little sicko, the Ph of my tap water was worse than I remember: 8.7! Has anybody ever heard of such a thing??? Sheesh. In fact, it was so high that I had to resort to vinegar. I also bumped up the SuperThrive a bit, to about 1/8 teaspoon per gallon instead a drop or two a gallon. The SuperThrive alone lowered the Ph over 1.5, and a splash of vinegar did the rest. Some people recommend against vinegar because they say it's not stable enough and your Ph will gradually creep back up. I find it's almost as stable as a commercial Ph-Down solution, at least in my limited experience, but it does require daily monitoring (which I'm doing anyway).

The PPM of my tap water was a little higher than I remember as well, about 160. But since I'm aiming for a PPM of around 1000 to 1200, it's still not horrible, and hopefully that 160 contains CaCO3, as stinky suspected.
SecondNut Reviewed by SecondNut on . OMG I can't tell what is wrong with my plant! [pics] Dangit. This is my first hydro, and evidently I'm screwing it up. Attached are 6 pics that show the sorry state of affairs. I've already pruned off several very crispy leaves, which is why the plant looks so sparse. I've tried searching through the problem threads, but I haven't found any pictures that quite match what mine is doing, so I'm asking for help. Some details: I switched over to 12/12 about a week ago. A couple of weeks ago I went to using distilled water, because my tap water has Rating: 5
