First let me say, the plants HAVE been flushed.. after about 265 gallons of water & 6 hours. LOL. Let me give you guys a lil more info. Dolomite is in the recipe for Super Soil and is in our soil as well. Our Ph has been between 6 and 6.5 for the entire grow. Plants are in 4 gallon, or more. buckets. The bat guano we got is watered in every four weeks. The only humic acid we could find is a water-in type, which is also every four weeks. We also are using a bloom booster, 0-10-10, that says to use in combination with your normal nutrients. When deficiency symptoms first showed, we fed with a little fish emulsion. We have a Shiva Skunk, a lil smaller, that went on flower 22 days before the rest. She shows no signs of problem and has been grown exactly like the rest. We'll post a pic of her in a little bit. Thanks for all the help thus far.
