flowering seems like its taking to long

hi everybody so hears whats up i am growing 4 plants each in a 10 gallon smart pots each plant has there own 400 watt light .....the leaves all look very healthy my stems are big and fatt my room stays about 77 during the day and 68/72 for night temps i am using dutch masters A/B ..plus sea weed and cal mag ..my ph 6.2 i like that for soiless my flowers are coming along but the seem to be goin way slower than what im used to.............reason im wrighting this thread is maybe there is some factor im over looking ...any brainstorms on what could be causing this ?

First off. How many hours are the lights on? And is the room Totally dark. What strain are they? Are they an Auto strain? How long ago did you flip them?

and secondly you need ph at min 6.4 to 7.0 anything under will produce lock out in soiless mediums have you in any way stressed them out so its repairing herself before the journy to completion also what kind of power are you useing

What is considered a soiless medium? I use Coco Coire, I always thought that was soiless. Coco is supposed to be between 5.3-5.8 PH. As is Rockwool.

i dont know what kind of power should i be using ?...lol no stress there jounry been a smooth one thats why im finding this so odd

Ok. Here is a mistake I did once. I moved lights and such when I flipped to flowering. And I left one light connected to a timer. This made it where I almost always had a light on during lights out.
Just an idea.
