  2. Check your Ph.

    Looks like the start of nute burn.

    Also, see the "clawing" on the blade tips ???

    That means its getting too much N.

    Id back off on those heavy nute feedings for that size of a plant.
    Go with 1/2 every second watering.

    It will clear up, give it a week or so.

    It also looks like its time for a transplant soon.

    U dont have any classic pest damage bro.

  3. I'm gonna go with my buddy Freakbro on this and say check your pH.

    Believe it or not, pH can tell you everything about whats wrong with your plant because certain nutrients tend to lock out at certain pH levels.

    Heres a graph for better clarification.

    You see, even if the nutrients are availiable in the soil, they may not be able to be distributed to the plant if the pH is too low. This is the reason that Nitrogen, Magnesium, Calcium, etc. problems are so common and tend to occur together, its because they both begin to lock out at about the same pH which is around 6.0-5.5 (for soil.)
