A friend finished a batch that didn't burn well and was black when it did. I thought it was dirty with ferts and wasn't flushed prop. She stoped nutes 4 weeks on the next batch as an experiment, and low and behold it didn't burn and was black when it did! The water supply is from a aquafir deep in the mountain, I discovered that the water is extreemly high in iron and magnanease, the PPM is approx. 1100+. Could this be the prob. all the minerals in the water, will a reverse osmosis filter unit remove all the metals in the water? does she need to buy water? As well, she uses lemons to correct the PH because the PH is 8.6 out of the tap, could lemons be a prob? thought it would be betteer than chem.
