OK I have 1 bubblicious, and 1 white widow My specs Soil Ocean forest Perlite Vermiculite Worm castings Lime PH 6.5ish 400w 2000k hps with 6 23w (100w eq) cfl 2700k placed around plants Temps were 78-80f lights on, 71f lights out Rh 45% Fox farm trio nutes Only the bottom leaves are canoeing under, they are not discolored or burned from nute, now they were fine a week ago and I adjusted the ventilation and after that the temps were around 86f and leaves temps were around 86f with a temp reader I use for my nitro truck motors. I checked some stuff today and noticed the duct going into the garage wasn't pointing up, it comes out behind my fridge in the garage and I had the duct turned up so it wouldn't blow against the back of fridge hurting airflow. Anyway I moved the fridge and it straight and sitting against almost flush on the back of the fridge. I believe this caused hi temps and will find out tonight when lights come on. Would heat cause this, its only on lower fan leaves, upper and middle are fine. I can post some pics in a couple hours.
Hey! How far are you into your grow? It seems like we have a similar setup! I'd like to follow your progress to see how my plants are doing. http://forum.grasscity.com/index.php?/topic/1340042-JHo%27s-Shiatsu-Massage
