There is nothing really you need to do in the start of flowering ie;week but at the end of week one get some advanced big bud add at 2ml per litre of water along with the base nutes add these for 4 week then at week 6 add pk 13/14 from canna,these two nutes will make a really big differance to your yeild.Go with 1.4 ec at week one of flowering,start of week 2 1.5 ec all the way through the flowering but flush at the end of week 4 with water for a day or so then back to nutes has soon has dry, then flush again at end of week 9 then chop let dry then smoke it.No matter what strain i all ways flower for min of 10 week sometimes 12/13,you will be amazed at the differance it makes letting your plants run for these few extra weeks.You should be flowering at about 2 ft tall if you have the height in the room,and they should throw you a min of 8/10 oz bone dry...................tyke
