plagron 70/30 coco blend media
Plagron cocos A+B (4mL of each per gallon)
Plagron power roots (2mL per gallon)
Cal/Mag(5mL per gallon)
Fish Sh!T(1mL per gallon)
Orca: liquid mycorrhizae (1mL per gallon)
Power Si (silicon) .5 Ml per gallon
average Ph/Ec (5.8-1.2)
Average temp/humidity (76/60%)

Getting sufficient run off every feed, just not sure if this is a burn or deficiency.. so many mixed opinions.

I think its a Mg deficiency, but i could be wrong. Lets see what others think. What is the ph/ec of input and runoff?
Input is 5.8-5.9pH/1.2-1.3Ec
Runoff is generally very close to what the input is. 5.8-5.9pH 1-1.2Ec

One of the only things I can think of that I switched was having to use tap water ONE day because of an ice storm. Couldn’t get to Whole Foods to get RO water. I let the tap water sit out for 18 hours or more but noticed it took much more pH down to bring the pH to 5.8
Also, humidity has spiked once to 85% for probably an hour. Could that have majorly effected the plants in this way?

Hard to say with all the stuff you're adding. Are you following a feed chart of any kind?

If you're a new grower I would simplify things down to only your base nutrients (A/B) and CalMag if necessary.

They do look deficient.

I’m following plagrons feed chart with the addition of a few other nutrients. Very small amounts. I’m starting to think it’s a deficiency as well.

I'm not familiar with the brand of fertilizer but i would skip the additives and just run the A/B and CalMag if your base nutrients don't have enough. If you're not sure just add around .3 EC of CalMag to you RO water and run your base nutrients to get your total EC up to 1.4/1.5 EC and see where that gets you. Increase your feed if they continue to look hungry. The damaged leaves wont repair themselves. Keep your eye on the new growth.

that doesn't help us saying with few other nutrients. There could be verity of problems that a plant can get deficiency. Lights, air, temps, humidity, water source, nutrients and then the experience of the grower. @jguit has a point and it might not be a bad idea to do a phed water only 3x the pot size to wash off all the salts and a final feeding with the A+B and see how the plant new growth reacts.

Above is your answer. Something is locking out uptake of nutrients. I tried to figure out the NPK of fish shit but could not find anything. Everything else you are at like 4-4-4 on your NPK levels which is out of wack. Using Tap water would have increase the available Calcium and Magnesium so I doubt that had anything to do with it and it is a further example that something is locking out because it does look like Mag Def but if you go deep enough down the rabbit hole you can find mulders chart https://www.nutriag.com/mulderschart/. you can see what it interacts with. 4-4-4 is not so good IMO. Have too much P and a little low on the K. You need to be around 4-2-5 in veg

I posted exactly what nutrients I’m using and how much, temp and Rh, input and runoff ph/ec, & said I’m using 5.8-5.9 RO water. I feel like I gave you a pretty decent amount of info to go off of. I’m using a 4ft t5 for veg light, have a carbon filter, and 2 small fans on at all times for air quality. I appreciate the feedback though. It’s much appreciated.

I just read “Potassium silicate is probably the cheapest silica you can add to your lineup but adds extra K, which can lock out calcium.” I’m taking a strong guess that the Power Si I introduced two weeks back is the culprit.. thoughts?

I have a good feeling it's cal/mag for the reson being veins are green but yellowing in between and those spots starting out dark have a feeling your gonna start seeing some small spots that resemble rust but calcium could be tricky to diagnose unless you see rust spots the it's straight forward but could look different and still be cal deficiency

That's why I ditched organics and gaia green just ain't got time to perfect my organic growing and at the time ended up with nitrogen toxicity added the all purpose and worm castings 😵

pH in soil is 6.3 - 6.6
pH in hydro is 5.4-5.6

You are feeding hydro in soil. Get your pH up to 6 at least. For you, 5.9 - 6.2
That's likely why your organics failed. Organic is 6.5

lol, you can see what you posted and what the additional are. Plus, i was just giving an example that everything in the room can reflect the plant.

I think the Ro plus the si has a rule and the nutrients are used in an order. I don't that order so can't help much with that. However, me and @jguit both agreed that doing a flush followed with the A+B nutrients only should set you up straight again.

Some sort of coco blend media he said. It looks like maybe a 50/50 soil coco mix.

Take a look at Power SI. Should not add P if it is Mono Silica Acid. but this is shooting from the hip. Try using just the bas at 5= say 35 percent, Cal mag at 5 mills per gallon and SI at full does. They should come right back.
