Must be trying the 18/6 light method. Causes way to many hermi prob for me. It certainly doesn't justify the ten or fifteen dollars per lamp increase in my bill at 1000 w per. Why have anything but a 24hour light during seedling and veg? No nutes, this is good. So many newbies see their first set of leaves and go right to work overdoseing their babies! They, should come back allright. As for your fourth attempt, I'm going to point you in the right direction! Now pay attention!! this is going to be invaluable. If You want a good grow as well as the knowlege that will last a lifetime, get online and order The Cannabis Grow Bible by greg green. I've purchased, read and shelfed, many books on the subject over my 35 + years of growing weed. This is the only book I've ever used as a total guide. This book covers everything from germinating to hash oil production. It has easy to comprehend chapters on gene manipulating, cross breading gorrilla farming hydro, soil organics, a quick guide for diagnosing your plants problems and 700 plus pictures to help you understand. It has a huge glossery and bibliography. I have changed MOST of my old methodology after getting this one. I've had it now for almost 4 years and it has never made it to the book shelf! peace.
