The specimen is in full flowering, fattening its buds progressively and releasing really strong aroma. We experienced slight nutrient build up, but we reacted immediately and the problem was solved in the matter of days. Because of the low temperature that we keep, the plant started to show colors. Soon the RH will be lowered as much as our equipment would allow. Since we did a little overfeed and there is plenty of nutrients in the substrate, we give only water with enzymes and humics in order to lower the salt build-up. We pushed the EC to 2.75, because we wanted to see how the plant would have react and the result was nutrient burn, which followed to discoloring on certain places. Thankfully because of the quick response the plant didn't suffer further stress and even regained some of the discoloration. Strong sativa dominance is occurring, which could strech the flowering weeks a bit more than expected.
Actually my very first use of Sugar Royal, indeed gave me that problem. My personal approach when the harvest could be seen behind the corner is to progressively star decreasing the nutrients. When the very last couple of weeks are at hand i flush really good, using flushing solution. Never had any problems ever since...
Have you been using Sugar Royal in other grows? I stopped using it bcs it didnt flush good and my nugs ended burning black and tasting weird. Normally i dont have this issue. I like to hear your experience :)
