Aside from the spike in macros, Jack's 321 don't look that bad now, lol.
no way your plants had def while feeding those insanely high numbersWhat is your opinion of the 3,2,1 N, Ca and Mg? Like the elevated levels and your knowledge of things? I've used GH @ 0.7 for years with only minor issues, mostly deficient from what I remember, so I know the girls can drink a strong drink if tasked to.
show me a pic of the magnesium defAre you of the opinion that most/all nutrient brands are in lockout dosages? I reduced GH to 70% strength, but I know growers us AN as is, same with Botanicare, and I presume [email protected] to be in the same ranges as the others. Either way, I've kept my schedules within the ranges you shared, but I believe I have a minor, but progressing Mg deficiency. I adjusted my feed mid week from 50ppm to about 60-65ppm with hopes of preventing further damage.
yes, most of the instructions are based on the higher levels of nutritional requirements needed for garden vegetables and replicated with some version of the work done by Hoagland, stiener, arnon and maybe two moreAre you of the opinion that most/all nutrient brands are in lockout dosages?

I can 2nd this I've been running 321 for years at full strength from clones to 10-14 days before harvest lockout is the only problem I've had a half strength dose of nutes with some recharge always fixes it I do the recharge every 2 weeks now so I don't run I to problemsno way your plants had def while feeding those insanely high numbers
more likely lock out
Not sure about that Mg problem, looks more like windburn to me.Here are 5 pics of my issue.
That would make sense if directly in front of the fan, but these pics are from top and bottom.Not sure about that Mg problem, looks more like windburn to me.

those are not from mg defThat would make sense if directly in front of the fan, but these pics are from top and bottom.
Edit - RH is down to ~50%. We had a wicked humid summer, but that's gone. still, this plant (original from seed) was vegged in high humidity.
Not Mg def. "Leaves turning yellow, or even white, with the veins remaining dark green is the best indicator of Magnesium deficiency". I have had this problem and it is not what you are experiencing.That would make sense if directly in front of the fan, but these pics are from top and bottom.

The EC ironically stays put throughout the week. Well maybe slightly downward, but negligibly at best. It's just the PH that spikes. When I first mix, I'm adding recommended dose of GH silica and also the fulvic/humic/kelp mix also has an upward pull, but I'm assuming after about a day, the base starts to take effect and it pulls the PH upwards near neutral (6.6-6.9).are you soaking the rockwool overnight before using it?
id soak the rockwool over night in 5.0 ph solution before using it
does the EC in your reservoir go up or down over a three days span?
try soaking the RW over nightafter that day(ish), a strong dose of PH down (1-1.5ml/Gal) gets it down below 6.0, then I just observe and correct as needed. Maybe the spike during that first day after mixing is causing my issues? I've read that those brown rusty spots on leaves are due to PH swings.
Edit - Usually when first mixing, I send a feeding through the medium and check PH again and get it right, but then there's one more feeding that I don't check before/after. It's the following day that I notice the spike, so at most, she gets one feeding that's possibly high PH.
Edit2 - I never prep my rockwool. Just soak in feed that they're currently getting, or sometimes plain RO as I'll be flushing the pots after transplant with the feed anyways and that will displace whatever's in the RW, so it gets reprogrammed so to speak.
