    You'll also want a bottle each of pH UP and pH DOWN, so you can adjust the pH after you measure it. If you're short on cash you can pick up the General Hydroponics water drop test kit. It only costs around $7 and you can get it at your grow/hydro store or possibly a garden center. For the price, the drops are very useful and pretty accurate.

    Even 2 teaspoons for a gallon and a half of water (1/2 strength of what it says on the bottle) of the nutes I use will drop my tap water from pH 8+ down to 5. I didn't think they affected it that much either, until I actually measured it!

    Lol 1/4 of a teaspoon. What is the recommended dose that the bottle says?

    Also if you want you can remove all those brown crispy leaves from the bottom of the plant, just leave the yellow ones until they turn brown and crispy as well. They should just come off with gentle pulling.

    Did you pick up some pH stuff yet? Let me know what the runoff pH is once you do!

    they do this near the end of they're lives, nothing you can do about it, she's using all her energy to produces buds not to feed herself, reduce the nutes and only give her water the last two weeks.
