I know they look good, but its been that same height for a week now just getting incredibly bushy, I thought they were suppose to grow like an inch a day or something lol. Watch one thing I did notice with when they were stuck at like 2 inches and literally looked like seedings for almost 3 weeks way air circulation, and was basically it, the second I got my inline fan and a box fan they started growing rapidly. I never even used nutrients, just some organic soil and tap water, just started a nutrient feed last night and only suppose to do it twice a week.
The thing you have to remember is Marijuana is a plant. Just like how you see random plants growing just find in nature with no outside control. So the thing I keep looking for is "What isnt like out doors" I am literally trying to recreate the outside world in my grow tent. I have the soil median, I have the light to replicate the sun, I use a timer to replicate night and day, use fans to replicate air movement *But I have a sneaking suspicion they arent working as well as they can therefore not recycling the air to their potential which perhaps could lead to co2 starving*. And its with this mindset that I have fixed ALOT of problems. I literally started with them under the light nothing else. then as time went noticed things, every day just about im adjusting something. If you have had a plant stuck at 8 inches for 4 months its good and bad, obviously you can sustain it in your environment, however there is an issue hindering growth. Maybe some kind of root lock?
