look man try not wory is the first thing coz u and the rest of us av problems of some degree on every grow unless ur sticking to the one strain that u av dialed in perfectly! but if not then probs will come n probs will go, its probly just a simple case of over watering, no big deal ! try av good air circulation via oscilating fans and if u aint got a PH pen then invest there ten pound on ebay that way u can make sure that part of the grow is taking care of as PH is very inportant and this can b regulated for as little as ten pound PPM pens trucheons etc r a lil more expensive and i am under the asumption that most growers dont use them though i wish i did av one, anyhowz chill out do ur homework and u will make it to the end !! on my last grow i had a number of problems wiv my 2 girls but they still yielded 6 and a half dry ounces of potent bud !!! good look grow on !!!
