I would ... but ... there are some tell tle signs of nute burn already - especially the Sweet Trainwreck Auto taller girls.
New growth coming through with yellow tips ... which I assume is nute burn.
Careful with that one...yellow tips also appear when the plants are under nourished..tip burn is what it is, the tips will burn ..if they remain yellow and don't start to change colour to a more orange/brown,it's not over feeding, in the last grow where i under fed, this was exactly how the leafs looked, yellow tipped and lighter than normal in shade of green right across the plant. As you say it's affecting the taller plant more, i.e. the one that probably needs the most feeding. I hope you sort it out brother. :pighug:
 
For what it's worth, the GH Flora Nova nute line that I'm rather partial to so far, has a transition where the recommend mixing the grow and bloom nutes for 1 week, for the reason @Hazy mention I suspect. And @GrowPotCheaply has been using Flora Nova bloom all the way for years https://www.autoflower.org/threads/how-get-huge-autos-with-coco-and-now-autopots.46286/#post-867259

Personally I transition/switch when they show sex 3-4 weeks old. And I increase the recommended feed amount by 50%......And if that ain't enough to ensure yellow leaf tips, it is upped to 75% until I can see they are being pushed to the limit before backing off. I also add extra phosphor a couple of times a week, together with canna boost and the other addies.

Here's the Sweet Trainwreck Auto I was referring to ...

Burn or malnutrition?
 
Any chance you get it out from under the HPS so i can get a better look at the over all colour? Is it the new growth only or across the whole plant?
Newer growth only

The older growth has that ongoing delamination issue.

This grow has quickly become my worst nightmare.

Hans i do the same thing, i always switch to bloom nutes around 10 days after showing sex, so say they sex on day 15 i will introduce bloom nutes on day 25, a little nugget i found right at the beginning of my adventures in one of SB's grows. You see there is still enough N being fed to the plants to allow for the stretch to continue without any problems, the plants i grow average around 80-100cm, not bad for autos. You see i think the opposite from the convention, i think by delaying the introduction if bloom nutes, you may be in fact slowing down the bloom process, therefore increasing the finishing time. Using the early switch method, i have found i can bring all my plants in on the advertised time, if not earlier. Now here comes the disclaimer... I have only done this with DP genetics Just thought i'd throw it out there brother. :bighug:
Yeah I would definitely agree with you that keeping them on grow nutes longer can delay the bloom process... and therefore also extend the veg phase. So I guess it depends on what you're going for... I prefer to max out the potential of the plant and grow some monsters so not really concerned with finishing times. ;)
