The various nutritional supplements tested (P, NPK, and HA) elicited distinct changes in cannabinoid content in the flowers as well as the inflorescence leaves (Figures 1, 2). These effects were organ and compound specific. For example, while neither P nor NPK treatment altered THC or CBD levels in the flowers, they did in fact lower THC and CBD content in the inflorescence leaves. For example, THC in the inflorescence leaves was reduced by 16 and 19% by P and NPK supplementation, respectively (Figure 1A). The reverse effect was observed for CBG, where although neither P nor NPK treatments affected inflorescence leaf content, NPK did significantly increase CBG levels in flowers by 71% (Figure 1D). NPK lowered CBN levels in both flowers and inflorescence leaves by 38 and 36%, respectively (Figure 1C). Surprisingly, HA lowered THC, CBD, and CBG levels in both flowers and inflorescence leaves. This trend was also observed with the minor cannabinoids (Figure 2), where HA treatment significantly lowered the levels of THC-C1, THCV, CBC, CBL, CBT, and DHC1 in both flowers and inflorescence leaves.
