Underfeeding and Weak Nutrition
The entire plant, both upper and lower leaves, will show lime or light green in color. The plant will not eat, drink or show growth. It is time to follow the 8 Step Remedy.

Overfeeding, Use of Too Strong Nutrients
The leaves will curl downward. They grow very dark dull flat green and then the tips show signs of burn. It is time to follow the 8 Step Remedy.

Nutritional Lockout
You know that you have made recent PH adjustments. You might know you may have used too much of the PH Adjustment Solution. You may have failed to test the PH often enough. You notice the plants did not eat or drink because they did not consume the same amount of water they used yesterday. You see rust spots. The large lower leaves are prematurely dying and you are not in the BLOOMING or FLOWERING stage. It is time to follow the 8 Step Remedy.

Wind Burn
You had the fan blowing downward toward the upper side of the leaves, instead of blowing up through the node spaces or toward the lights. You observe the leaves becoming dry or even crispy, perhaps shriveling, and the tips curling upward. The leaves do not appear glossy, moist and vibrant. It is time to follow the 8 Step Remedy.

Water, Nutrition Solution or Roots Are Discolored Brown Or Have an Unpleasant Odor
You notice your water is becoming brownish in color, or smells distasteful. Your solution does not smell pleasant and appetizing like fresh lettuce. Your roots are not the same shade of white that they once were a week ago. It is time to follow the 8 Step Remedy.
