Hi, Some one I know has 4 cheese plants that are looking a bit worse for wear! They are 9 weeks into veg from cuttings. 600w hps from start on 18/6. The temp is high 90's during lights on and RH is really low at about 36%. The plants are some what root bound. I know they need to be cooler and the RH higher and also I know they could use some repoting (although they are in 1 gal pots). The biggest issue is yellowing leaves although the new growth is green as ya like. Any way any info would be nice.
