Week 2
During Week 2, the plants continued their transition out of the post-transplant phase but began to clearly express a higher nutritional demand. While root development was progressing, all plants showed visible deficiency symptoms, mainly lighter foliage and chlorosis affecting leaves.
The 1st feeding of the week was maintained at EC 1.1, which quickly proved to be insufficient for the plants’ current growth rate. In response, the EC was gradually increased to 1.6 for the last feeding of the week. Over the course of the week in order to better support vegetative development and address the observed deficiencies. This adjustment led to partial improvement, although the issue is not yet fully resolved at the end of Week 2.
Apical growth remains active and responsive, new growth appears healthier and more vigorous, internodal spacing stays under control, but stems are still relatively thin. This confirms that the plants are still in a catch-up phase following an initial underfeeding, rather than experiencing nutrient lockout or stress. The contrast between older pale leaves and fresher top growth supports this interpretation.
Close monitoring of leaf color, stem thickness, and overall vigor will be key going into the next stage, with further adjustments made only if the plants clearly request it.
