Nutrient lockout

So I've got a couple autoflowers here, same start time, water and food out of the same 5 gallon bucket. Coco coir medium for both.

I do admit I've probably over watered the lady on the left, but probably the right as well. Different strains, so tolerance to my bullshit is different apparently.

I'm several weeks out from harvest, I'm wondering if its safe to do a flush this close when I'd be doing my normal preharvest flush.

Better to wait and flush 2 weeks out, or to flush em real quick and get them back on nutes until 2 weeks out?

I wouldn't flush them....just mix up new nutrient that suits you and run enough through the pots to rinse out any excess salts and reset your medium. Your plant won't miss a beat, otherwise, she's not going to like you. Your pic looks like she's short on P and K, which isn't unusual in flower.

What are you feeding them btw?

Sounds much more reasonable than the options I thought i had. I'll do that asap, appreciate the help.

For those two girls I've been using Sensi Grow A and B and calmag.
They both were perfect until this last batch of water and food, I raised it up and obviously went too high with it.

I went full strength with Sensi, after some asshole on reddit convinced me I was crazy for only feeding it at half strength (in soil), and claimed he has always had amazing results feeding it full strength. It took about 3 full strength feedings (a week apart) of Sensi Bloom to get severe N tox & lockout and I the entire grow I watered and fed until I got about 3-4 liters of run-off from 7 gal pots. I never had issues running that line at 1/2 dose once a week.

Well goddamn... I followed similar advice, and the minute I got past 30ml of each A and B per 5 gallon bucket of water my girl started to lock out hard, so im taking her back to 30ml because she seemed happy there.
Funny that the other two flowering plants there have been fed the same crazy high nutes and show no signs (so far) of lockout.

You think I should dial them back as well? To avoid the potential problem hitting them, or should I continue on with those 2 plants and see what happenes?

Thanks guys!

Some strains/phenos may be able to handle it but I personally feel better staying on the safe side by feeding them less.

I fed mine a week ago and they seem fine. It was a half feeding, i might feed them again, they are getting thirsty. i wouldnt change the nutrient schedule if someone told me to especially if they were doing well. I am using way cheaper nutrients than you tho "GH". It was also their only feeding so far they are forty something days old. I wont change it unless something is going on then ill ask

if it aint broke dont fix it
