Wassup Juggalo,
I think what happend here is you ripped off the feeder roots. To explain the root's and its growth patterns im going to break it down into 2 parts. The first part- the thick white root's are your water root's, there main function is to find water and mainline it up to the plant, it also helps keep the plant stable from wind or bad weather, it's like yur plants anchor!. The second part- Are the small white feeder roots that branch off your main water root. These feeder roots function is to mainly supply all the nutrients the plant needs, these small thin roots are easly damaged by transplants as they rip and tear at will during transplants. I think what happend was when you transplanted, the feeder roots simply were ripped off from the water roots. This would cause a stall for about 5-7 days in which this time period, you should be feeding your plant hormones and vitamins. Ease off the nitrogen right now, for fast root growth you should have higher levels of P-K in your soil. Keep us posted and i hope this helps out man!!
Peace and love!
Roken!
