    Any bugs? I found some web on the plants yesterday, and something that could be bugs, but i cant scratch them off. Its like very small black spots

    My problem is: My plants are 3 weeks and two days into flowering and generally looking good, but now one is really starting to yellow. Still only the lower leaves of the stem, probably up as far as 10-15 cm. But the higher leaves also has a brighter yellowish green colour than the ones of her sisters.
    I've taken some pictures to help.

  2. Anyone? Its more yellow today, but no bugs to be found. Ive been looking all over with a 30x magnifying glass :hello:
  3. Try not to fertilize the next time you're watering, check ph vaerdien og klip de yellowing blade af, det kan ogsaa vaere den mangler oxygen. tag en dag ad gangen det skal nok loese sig.

  4. super, har købt ph måler idag. Men lækkert main cola right?
