I've been following this thread on and off for a few weeks now as I'm growing Wonder Woman as well! Mine were vegged for 5 weeks from seed and are now into the middle of their third week of flowering and looking great! Started with 10 and 5 ended up males which were tossed! Two more turned hermi about two weeks into flowering and they too were tossed. The remaining three are all very similar in growth and appearance. Short, stocky with deep green, almost bordering black leaves that have heavily serrated margins.
I use Humboldt nutes and the ph will always rise in my res. tank, even just over night! I use a meter as the sticks just seem to vague and left up to interpretation for me! They're running (also 13 Swiss Cheese) under 4- 1K HPS , open hooded lights in 5 gal grow bags with mix of 65% perlite, 20% coir (coco), and 15% peat. Hand watering with a drain to waste method and nutes at 1200ppm. Temps run around 82F to 85F w/ lights on, and 72F to 75F lights off. Have cloned two of them as well as two of the cheeses as they are growing awesome! Will drop some pics ina couple more weeks as they near finishing. Take care & good growing.
