i've done well on my first grow. i'm prepping for round two. where i live we catch the water off the roof and it goes into a water tank; then is pumped into the house. we don't have wells here. water ph is 6.0 at 50 to 100 ppm( it's rain water) my gutters have algae or mold in them all the time and always will. i used this water in my grow and it worked just ok. i noticed the roots at week 13 turning kinda dark and seemed to stop growing new roots. the plants are about done and i'm looking for an answer on how to purify the water i'm going to use in the next grow.i use organics so h2o2 is not an option. maybe switch nutes? maybe h2o2 in the water for a day or two before adding it to the res with nutes? i grow dwc with 400w hps i vegg 7 weeks and am in week 7 of flower. water quality is very important in my dwc. what to do?
