usin the ferts as it says on the bottle,im usin bio-bizz ferts,i flushed the plants with fresh water about a week into flowerin(thought the yellowin was over-fert) to see if it would improve the yellowin but never done them any favours i dont think.
temps never below 65f and never above 85f,humidity various from around 38-40% upto 59%,swapped from 250w mh to 250w hps for flowerin,done a ph test a few days ago,reading neutral (shitty single ph test kit)
plants watered usually every 3 days when the pots feel light,there in 1 gallon pots,exractor fan fitted in grow space,which i left running 24/7 from the word GO,but past few nights decided to switch the fan off when the lights go off to try and keep a bit heat in the grow space and keep the humidity at a good level,cant think of anythin else at the mo
