Today was orca day. Added it in for the last watering and emptied/cleaned the res. For some reason it keeps getting nasty after a couple of days? I never had this problem using just the dynagrow in the smaller res filling daily. I added protekt and mag pro when I went to the bigger res and filling every other day. I did add some hydroguard which I believe has made issues for me in the past. Maybe it's the hydroguard? I have a small fountain pump that I thought would keep the water aerated enough to keep the nasties away, maybe not? Dunno, not the end of the world, if I had the money I would order some more z7 and see if that helped but I'm out at the moment.
With the weather warning up I have cranked up the IPM been spraying daily/every couple days with dynagrow and neem oil. Despite that I found some little critters on the gorilla Bomb clones today. So I will continue spraying for a few more days and hopefully it takes care of them. If not I'll dip them in h2o2 before they get moved in with the rest of the veg wave destined for tent#2 in a couple weeks
