I think your doing a fine job and theyre going to use up a pile of that N in the stretch and bud formation. Great grow.
So she's ok then ? I'm just going continue with the bloom for now until I get few lower yellows I have got a few clawed leaves deep in the canopy towards the bottom they small leaves on some popcorn bud sites think they are like that from lack of light though

Only n she's getting is from the bloom I'm giving her
If it's not an option to decrease N then make sure too flush properly and give her time to use up the excess N (you will see fan leaves start to yellow this is the plant pulling N from non-vital points to conserve for bud sites) nothing is more disappointing then potent bud that isn't flushed and cured properly.

Just drop the N down after shes done stretching and especially for the last 2-3 weeks too much N will make for some unpleasant smoke
This is not true- unpleasant taste comes from improper curing. In fact, current Colorado best practice is to add back a small amount of N in the last two weeks in order for the plant to finish strong.

adding back N means it had to have been dropped down at some point. I never said ZERO N. I said make sure to flush properly (at the end) not completely starve it and seeing as the plant does very little growing in the last 2 weeks you dont need quite as much food. Clearly you have never had bud that had nute build up in the roots and was never flushed or you wouldn't be so closed minded. Yes, poor curing is the #1 cause of buds smoking poorly but it is NOT the only factor.

Whoa, ease up tiger- simple misunderstanding, no need to get all 'close minded' with it.

The point of ensuring a lil N at the end- however you do it- is precisely to give the plant something to use up any excess nutes in its tissues before harvey.

In other words, we're on the same page...

The snap, crackle n pop weed is usually a result of growers who overfeed phosphorus at the end to get their plants to bulk up. Yes it works but only at the expense of flavor, potency- and good taste.

I've found that feeding moderate amounts of P throughout peak bloom does a much better job, and having a bit of N available at the end helps bring it all together nicely.

Sorry about thay I just wanted to clarify the importance of flushing when using synthetic nutes but I'm glad you said something because if I wasn't coming across clear about what i meant to you odds are someone else might have misunderstood as well. As long as we're all on the same page

In this case the N is in the flowering nutes so there's no room for manipulation of P or N without effecting everything together.
