The 36% potassium (as K₂O) can help support cell wall thickness for that perfect crunch, resistance to wilting under grow lights, and post-harvest quality. Without adequate potassium, lettuce tends to become limp and can lose market value more quickly.

If pH is too high, iron locks out (causing yellow leaves). If too low, calcium locks out (causing tip burn). For hydroponics, keep pH between 5.8-6.2 for the best balance. In soil, aim for 6.0-6.5. Check pH daily in hydroponic systems — lettuce responds quickly to pH drift.
