Its my first grow ever so take what i say with a grain of salt........looks to me you prob should've trimmed her up real nice before flowering. Or fuck it maybe during flowering if its Really that bushy.....i had the same problem when i topped my main plant about 16 times. So i had like 32 main colas. It looked ok until it started to get really bushy and leaves started to overlap one another. It got to the point where all my top nugs looked great but when i moved the t op colas over there were a shit ton of premature buds. Looked like light never touched them. all the hairs were whitwwhite not orange like they should've been by now. So i trimmed it up and in 5 days they looked a lot better. Nugs seemed to bw growing at a faster rate.... moral of the story is those nugs at the bottom or middle are not gwtting enough light.can I give nutes again or continue the water flush? From roots to tips. I did something wrong.
