Thanks Lads
Hey Chimera thanks for the help, I have dropped it down to 5.6/7 as you suggested.
HOT !!!!
Our Day/Night Temp is around 28-31c all year, Humidity 60-100%, the growroom internal temp is avg about 29c, up to 31c on the real hot days. I am struggling to keep it down. Managing to keep the nutes at about 26c by constant circulation.
Any ideas?
