    I have 2 plants growing in an small 1m by 1m by 1.5m box. It has an extraction fan on the top, passive intake vents on the bottom. 2 x 250w LED lamps + 5 x 20w Florescent. Humidity and temperature are kept constant at 50% humidity and 22 Degrees C. The entire room is covered in reflective Mylar.
     
    The plants are about 2 weeks into flower but the taller flower was showing these signs before flower. The leaves of the new shoots aren't healthly looking and droop quite a bit. The older (bottom) leaves are turning pale and the stems are going red/purple.
     
    I have been watering with a nutrient solution produced inhouse by the person I got my equipment from. But I have been following the dosage instructions. But the last time I watered I was using normal water (pH 6.7) with 30ml added Wondersol.
     
    Any help would be greatly appreciated.

     
  2. Temps and humidity are good but if your getting like solid purple areas on the main stalk that is a cal/mag deficiency. In mid to late flowering leaves will naturaly die off as the plant is drawing more food reserves from the leaves to help produce buds. If you start losing fan leaves to soon or to fast then you may need to bump up the nitrogen feeding just a little bit for a couple of feeds.
