Here's the skinny

Three five gal rezzes, 400watt hps, Ph between 5.5 and 6, air temp 74-68 water temp constant 64. Using dynagrow Grow nutrients recommended by local hydro store at recommended strength, 7-9-5. 12"long airstones in each rez bubbles aplenty. Good ventilation and air movement. Been about four weeks now and only 6" tall, but with three opposing leaf sets and two inch shoots from nodes. Stems r 1/8 to 1/4 inch thick. Definitely growing but seems slow to me. Using tap water, maybe chlorine? Any way to dissipate chlorine from water? Roots healthy, change water and clean rez twice a week no algae or slime. Water level just touching bottom of pots.

New to playing in water so be gentle. Getting digital Ph meter today. Light is three feet above plants in grow cabinet. Any suggestions and ideas welcome.

I had similar issues my first DWC grow ph would not stay steady plants growing very slowly,finally figured out that the ppm,s in the tap water was around 225 or higher from the start. Not knowing what was in the water causing the high ppm was exactly what was keeping the ph from staying steady and would not allow the roots to uptake,i installed reverse osmosis filter system got ppm down to around .025 at.this.point the i adjusted the ph and it stayed 5.8 for a month never had to change it,but with reverse osmosis the calcium and magnesium is removed so you must add cal.mag . As far as root rot from water temps being to high mine tirned brownish yellow so all i did was add a.tablespoon of hydrogen peroxide and within a week roots were white again
