i have plants in veg that are about 10 inches high and i wanted to start flowering,they have been vegging under t5,s for a month,it got a bit cold so i alternated them under the hps and the t5,s,then i noticed my leafs looking waxy and the sides curling up,as well as some new growth haveing a brown tinge,they look nice and bushy,but that wax look has me worried,im thinking salt build up because of change of water this time of year,or the cold it got down to 62 but not lower,any suggestions,thanks.i also sprayed for fungus and that.sorry no pics dont know how to download,which is to bad because i hear computer sex is the new thing lol.
