yes was using homebase tomato food 4.0-2.0-6.0 had no problems using that on its own, but then i changed to dutch pro no info on the bottle i done exactly what it said on the tin, it says nothing about npk on the bottle i used half what it said on the bottle for first feed, and the full dose for the second feed, it says its for autos this is my first grow so i am confused should i just go back to the tomato food,,,i did flush before i changed to bloom and booster,,,,,,should i have used the booster already still have 4/5 weeks left

That isn't bad c.doc, just cut back a little on the ferts. Go back to 1/2 strength and slowly work your way up to full. You have 4/5 weeks left, that is plenty of time to pack on some weight. No need to rush things. I always burn mine a bit trying to find her breaking point.
