im having serious problems with ph rising like wild fire. it raises about a half point every 5-6 hours and im going through alot of pH down. my plants are showing signs of stress and im constantly working so i cant always be around to lower the pH every couple hours. what should i do?

im using aeroponics; watering 15on/15off
nutes = sensigrow 2-part, hygrozyme, b-52
temp = 75F hum.= 50%
lighting = 8 2' T5 HO @ 6500K
 
temp insignificant on ph, what are your res temps? above 70 you probly got some kind of funk growing in yr water. do res change and keep res temps<70
