Well Bob, its alittle too late. I killed 2 sativas and kept my best. I topped the 3 2 days ago and once they start new life, I am trowing them into flowering. I am definetely going to LST the 2 sativas. they are big. 4 times the size of my Indica. I was thinkiing of Buying all fox farm nutes in a month or so when I start on my next grow of papaya and bubblicious that I got in the mail yesterday! I will consider the soil also. I need a dig. ph reader also. I think its just a pain to try to test soil.
