Overnuted, now what.

I'm growing White Widow Autos. Five.
3GAL containers in 3/4 BioBizz lightmix 1/4 perlite.
2 1500 W LED
1 150 HPS
5x5 tent.
humidity 45-50%
temp +- 76

We are in mid bloom.

I switched to Maxibloom powder as an experiment
I used 1 tsp/Gal as directed.
I failed to mix the powder well enough and wound up over-nuting some of my White Widow Autos.

No expert, but it doesn't look like a horrid case.
The day after I saw the signs and did a 2-gal flush. That was yesterday. Today I felt underflushed and ran 4 gals each through them.

I keep a handle on my pH, I used distilled mixed with tap gives me a perfect 6.3-4-5 range.

My plan is to give plan distilled H20 the rest of the week and then try 1/2 MIXED REALLY WELL of the same mix.

My question(s) are - I read about overnuting, and they talk transplant ewwwwww. I think I'm ok with my plan. Anyone? Should I try 1/4 first instead of 1/2? Should I stay away from the hi power ferts?

Hep me.

You burned them. Whatever you did do less now. You should be cycling feed to water or flush once a week.

No point using plan distilled water, it won’t achieve anything. Allow water to stand for 24 hours. The amount of water used to flush is not a guide to go from, but measuring the run-off with an ec truncheon/meter. At this stage of flowering you should flush with a very weak solution 1.0-1.2 until the ec runoff falls to around 1.4, if using synthetics. This flush should be done in one session and ensure pots are up off the floor. Do not start feeding regime until they are ready for next watering, then use sparingly. Biobizz lightmix is a little acidic, so give it a quarter strength of calmag when you resume feeding. Your last photo suggests this.
