So maybe drop like one or two single drops of ph up to let it drift up words the see what happens maybe?
Whoa what is happening!!!

Apologies in advance but what do you mean a 12hr flush? And by plain ph water do you mean ro water? Which would mean I would have to go out and buy 35 gallons on ro water since I don’t have a ro system yet.

i just noticed you are in a multi site setup. can you isolate these 2 plants by putting each one in it's own 5 gal bucket temporarily?Apologies in advance but what do you mean a 12hr flush? And by plain ph water do you mean ro water? Which would mean I would have to go out and buy 35 gallons on ro water since I don’t have a ro system yet.
then give plain water (tap, ro, well, distilled) without nutes. i think you overfed them which led to nute lockout. the flush will break that lockout. and then start back on lighter nutes.
the foliar feed with cal/mg is the fastest way to fix a Ca deficiency (the rust spots)

Oh gotcha! I can take them out yes won’t be easy but it can be done. So basically you’re saying take those two plants throw them in regular tap ph water then completely flush/drain my whole system then fill it back with regular tap water then put my plants that are in the buckets back in then start nutes all over again just super lite. Am I understanding that correctly? Will it affect my other plants though all the rest seem fine it’s just those specific strain ones that are doing it. However my tap comes out around 330ppm. That still fine?

not quite. can you get 2 5 gallon buckets with an airstone in each one? take the 2 plants out of your rdwc and put one in each 5 gal bucket as a standalone dwc until you can fix them. if you live near a walmart or similar, you'd need a cheap airpump, some airline, 2 airstones and 2 5gallon buckets.
that's kinda the problem with a multi site system. if one (or 2 ) plants have troubles, you risk messing up the other plants that don't have a problem.
that make sense?

Renute it and do it now Your plants are mostly jacked from the hot nutes this needs to be corrected before anything else.
Run your veg ppm at 450 and when you go to flower run the first week at 450 and then bump it up each week so that full flower will be about 700 ppms then lower it back down to 450 for the last week then to the flush.

Yep makes sense! Does it have to be a new stone as well? I say that because how the pot is set up is when you left the lid the stone comes with it it’s just how it’s wired in so is it mandatory to get one or no? If not I could just simple pick it up airstone and all and put it in a new bucket and be done.

Even if the other plants aren’t showing any signs at all they are all jacked? Not even one brown spot at all or anything else noticeable least to my eyes yet I’m still learning so. I became the typical noob and burn the crap out of my plants but hey least I got that outta the way right so now I know going forward what NOT to do. Haha. Unfortunately I can’t fix them right now I’m at work I work nights so it’ll have to be first thing tomorrow so fingers crossed. Thanks for the help! Also any suggestions on a ro system.

nope, i see exactly what you mean in that pic. yeah, just set that whole thing into a separate 5 gal bucket. then do a 12 hr flush on the 2 bad ones. it would be better if you could buy some RO water from walmart to flush them with since your water is already 330 ppms. and then use more RO water with maybe 300ppms of nutes ( instead of your tap plus 300ppms of nutes or 660 ppm total) on those 2 plants that are in standalone buckets for 3 to 5 days and i bet the new growth will start to look better. once they recover, put them back in the rdwc setup and away you go.

I think that the plant you posted is showing signs of low mag. All the plants are and will be different and have different tolerances. So even if they look fine maybe deep down the flowering ppm your giving your little plants in veg are hurting them in a way you cant see. Like stunted/slow growth for one.

You lost me. Hah. I’m so sorry. Am I to leave them in for 12hrs then put them back or flush for 12hrs with ph water with my tap at 300ish for a couple days then at add little nutes back or do 50/50 tap and ro or just ro water which I can do easily. I made this complicated did I. Damnit.

Oh I’m not saying there isn’t any issue yet I just didn’t see any I’m sure there is they are FAR from perfect. So outside of what rky said which is a great idea which I was going to do what would you suggest?

330 ppm is quite a bit for tap water. i agree if you're gonna grow long term gonna need an RO filter
i don't think you have any deficiency. doesnt make sense to have deficiency with 1000ppm of megacrop.
you said your pH has never been over 6, right? so calcium is completely locked out and magnesium is probably locked out too. so you have a whole bunch of cal and mg in the water that cant be absorbed by the roots.
i would reset your res with RO/distilled water, 300ppm of megacrop and a 6.2 pH
letting your pH drift up and down a bit is absolutely key. 5.8-6.2. then increase to ~800 ppm of megacrop as plants get larger. you'll never need more than that.

I think you need to lower the ppms .........and use r/o water or get r/o water from the store or invest in a r/o system ..when I tried tap with a high ppm I didnt do very well with my growing results,.......... I dont think you need to flush anything right now till begore the final chop is when I flush. In hydro that is ...flushing when in dirt in the middle of a grow helps if your soil is too hot. Flushing in hydro cuz the rez is too hot doesnt make sense to me.

for a flush you need to do it with RO or distilled. your tap is too high ppm to flush with in my opinion.
and then after the flush, i would also use RO water and light nutes (300pmm maybe) for the next 3 to 5 days and i bet your new growth looks better.

i was recommending to flush b/c he's obviously nute locked 2 of his plants. there's no way he'd have any deficiencies with an EC of 2 unless it was nute lockout.
a 12 hr flush will break the nute lock and then he can start feeding lighter nutes

Update: Well transplanted the one into its little hospital for now least for the 12hrs suggest and see how she does the other in question hasn’t gotten worse looks to be the same so if something does changes I have everything ready for her if she takes a dive. Had to make a little hat for the empty bucket so the lights don’t heat my water up. Hah. Got these other little ones showing yellow tops an some bottoms I wad told it was due to light burn or bleaching because I’m running all LEDs? Seems to be growing fine though so I dunno?. Thanks for all the help and suggestions from everyone! Oh, I’ve also purchased a R.O. System as well. Not the greatest but I think for now it’ll do the job. Hydro-Logic Stealth RO150.

Thanks! I think I’m going to do that and also let that one sit on the side lines for a little bit then change my res out with ro and nutes however I’m actually fresh out of megacrop I need to order more.
