problems with my water supply
Dear Ron, I have been growing hydroponically for some time now and have encountered some
major problems with my water supply. My tap water reads at 400 ppm. Now i am using general hydroponics 3 part formula and have encountered some problems. my feeding dose is the general purpose of 1 teaspoon per gallon of micro,one and a half teaspoon of grow, and one teaspoon for bloom. after i administer the micro, i test my ppm and it is 660 ppm, i then proceed to add the grow and my ppm is at 1130, after i administer bloom, my ppm reads 1330. my problem is that i started seeing signs of overfertilization (leaves curling down, claw like, very dry, brown spots, shriveling of leaves ) when i had my ppm at 1200, it would be simple enough to lower my ppm but i also saw signs of nitrogen deficiency (yellowing of leaves). Is this perhaps because the high ppm of the tap water is adding more phosophorus potassium, and is also blocking out nitrogen somehow. how much of each part of the nutrient should i use if my tap water is at 400 ppm, and my plants show overfertilization at 1200, and their are signs of nitrogen defeciency. i am growing tomatoes via geolite and am watering 6 times daily for 30 minutes each watering cycle and am growing in an ebb and flow table under a 1000 watt metal halide, my ph is between 6.0 and 6.7. Thanks |

I would say that it might be your tap water. You can try a water filter to eliminate the unwanted crap
that they put in tap water just to make it drinkable. Ron |
