Alright GB, I hear you may have your products? And since you already told us you have an Accurate8, tell us how everything worked out with your pH? Did it react quickly and drop like a rock? If it went a little too far, don't fret, it will come back up after the initial hit of aluminum wears off. If it isn't far enough just mix up a little more and gently pour it into the soil. One thing I forgot to tell you, do not get that on your leaves or smaller stems, it will kill them dead. Quickly! Like within 24 hours quickly.
Also, when foliar feeding, it is best to do it right before the lights come on in your room. When the temperature is at it's lowest. The stomata on the leaves will be closed at that time. Spray both sides of the leaves pretty good and let it be. As the temperature warms up the stomata will slowly open and the plant will begin taking in the nutrients, somewhere around upper 70's to lower 80's is the perfect temperature. Tomorrow, get you some clean water and spray them again, same time, with just pure water. That will allow the plant to take up what is left on the leaves and help clean the stomata and keep them functioning properly.
