PJ, I honestly think your yellowing was user error and don't think you can blame it on the product. I just pulled this Kush down without any yellowing at 8.5 weeks
I had run Floranova in the past and didn't have as good of results and didn't like the sludgy mess. I also felt like I couldn't get all of it out of the bottle! Floranova is also more expensive off the shelf. With Veg+Bloom I am paying around $15 cents for a gallon of nutrient solution these days and my plants only need a liter or two every other day.
