I have done a good amount of research but would like some more input. 
      -Im using Sensi Grow Two part Grow/Bloom. 4 plants, Three headband clones about 3-4 weeks old, and a lemon haze seedling that is almost ready for a pot.
      - My plants are under a 600 watt metal halide for veg, HPS for bloom.
      - They are in a 4 gallon reservoir. I also have another 4 gallon res that pumps  by Vidx">water[​IMG] through the plant res. 
      - I have a  by Vidx">ph meter[​IMG], and ppm meter. The ph is steady at 5.8-6.0. No humidity/temp meter.
      \t- Ventilation is an inline fan, and a small fan blowing on the plants. 
      -Problems thus far include.
      \t1- Purple stems
      \t2- algae in the res (Fixed by using another external res, ancient forest, and some other things.)
      \t3- White spots on leaves
      \t4- yellowish-brown leaves
      \t5- brown spots on leaves
      Here are some pics. 
      \tANY SUGGESTIONS WOULD BE MUCH APPRECIATED!      </blockquote>\t

    Is your hydro STAYING at 5.8-6.0? How often do you check PH/PPM?
     
    Don't worry about purple stems IMO, from what I have read, some say its lack of nitrogen and some say its genes.  My plants that have purple tinted stems I know have lush new green growth so  I feel nitrogen is BS.
     
    Algae issue, just change your res every week and you SHOULD be ok but algae forms when light is present.  You could use BLACK totes in future grows or ghetto wrap it with duck tape so light doesn't get in.
     
     
    Nute LockOut PH Ranges
    (N) - 4.5-5.0
    (P) - 6.0-8.5
    (K) - 4.0-4.5, 6.0-6.5
    (Mg) - 2.0-5.7
    (Ca) - 2.0-5.3
    (Zn) - 5.7-8.5
    (Fe) - 2.0-3.5
    (S) - 2.0-5.5
    (Mn) - 2.0-4.5
     - 2.0-5.0
    (Cu) - 6.5-9.0
    (Mo) - 2.0-5.5

    You want your PH to be ~ 5.8
     
    If I were to GUESS whats wrong with your plant, its definately your PH because if your following some kind of guided feeding you only have to watch your PH/PPM. I THINK its locking out Potassium.
     
    I did DWC on 2 grows, while I did have a good end product. I recommend soil organics to everyone.  Saves such a headache, it really doesn't get easier.
     
    Any questions feel free to ask, also anyone elses input on nutrient lockout or if somethings incorrect please let me know so I can learn myself :)
