~5 weeks into flowering, stopped growing???

So this is my first time flowering. I am growing under a CFL and my plant is doing great. It will be 5 weeks into flowering on Monday. The thing is, it stopped growing completely. The hairs are staring to darken a little, but the main cola has been at the same height for about 4 days now. Is this normal? I have been suspecting that the plant is root bound, but if this is a normal occurence, then I guess I shouldn't worry much. Thanks!

this happened me on my first grow i thought they were root bound an got bigger pots , they didnt grow any bigger , yours wil probaly b ready to chop on week 8 or 9 , buds will swell up closer to harvest.

around week 5 the plants get into a rut and stopping growing so much, also a plant will only stretch upward so far before it stops and forms its main cola, so you wont be seeing any vertical growth now only fattening up buds ur fine man
