well this is how my res.. change goes. I take a water pump and pump all the old solution out of the res. once its out I mix a new solution in a separate rubbermaid tub. I then stirred it for about a minute then take the ppm and ph with my meter. once its at the level i like i take the water pump and pump it back into the res.. Ive been pretty good with checking the ppm & ph regularly which is to my surprise that you think it is a nute problem. I was thinking it might be heat stress. I have a therm/hygrometer that records the min/max humidy and temp levels each day. My max is usually around. 85-90 degrees 60-90% humidity. The min is usually about 20-30% humidity and 62-66 degrees. I have a exhaust fan(i think 172 cfm) that blows air out and I havent made a hole for the intake because there is a 3/4" gap between the floor and the door. Yesterday I raised the 600 hps all the way up to the max(had to drill it into the ceiling) and it was at about 17" away from the tops and now its prob about 22" away. Do you think I should cut a new hole for the intake? would that help with the temp? as I said from the pics of heat stress on this site kinda look like mine and the descriptions somewhat match.
