Yellow lettuce in hydroponics? Before adding more fertilizer, look at WHERE the yellow starts. Here are the 5 most common causes and how to fix each one.
1. pH too high (iron gets locked out)
2. No iron in your mix (new leaves yellow, veins stay green)
3. Low nitrogen (old, lower leaves yellow first)
4. Low magnesium (yellow between the veins on older leaves)
5. Root problems (warm water, low oxygen)
