Combined runoff 3.5L Ec=1.95 ph=6.0💧 #1 Height= 65CM Dist= 37CM DLI=32.4 Rough week really, apart from day 91 it's been so hot here it's played havoc with the grow. This is why i should have taken the scheduled break. I don't think the weather has done much damage but it can't carry on like that for much longer. This week could have been worse. I'm checking all plants incase the heat has caused any to hermie. #1 is shaping up quite nice. Has struggled a little with this heat wave.
