The Adventures of Bubbasquanch and Mango Smile

Day 49 (F21) - Think stretching done? Mango Smile (MS) leads in height at 30" and Bubbasquanch (BS) at 21". PPFD at tallest cola now at 950 ppfd but most other colas under 850. Kootmed's Jacks Feed chart still being followed: daily (per gallon) = 2.5 ml Armor Si + 3.6 grams Jack's 5-12-26 + 2.4 grams Jack's Cal-Nitrate + 1.2 grams Epsom Salt and weekly (per gallon) = 1/2 tsp Real Grower's Recharge + 2 tbsp Molasses. Also, not sure why but the nice, mango smell has gone and I hope it comes back. So tempted to add some flower booster or maybe increase Jack's dosage to 125%. Since there's no sign of nute burn on leaf tips, maybe they're not being pushed enough. PPM of current nutrient mix is 1100 and ppm of runoff is 1650.
