Nancy Drew and the riddle of the sick plants 2: Electric boogaloo!

Hello again RIU, it seems like my plant problems from previous experiences isn't yet over (see https://www.rollitup.org/t/need-help-identifying-issue-in-multi-strain-grow-soil.831240/ )

However from last time some developments have happened, and for once I've actually got some proper pictures this time so I thought I'd throw 'em out here and get to the root of this problem (I should be taken out behind the shed and be shot for such shitty puns) before I flip it to 12/12 in two weeks or so.

Basic information;

Plant Age: 3.5 weeks.

Soil: 100% dark soil with a medium amounts of neutrients, I can't give away the brand because it would be way to revealing, suffice to say it's considered to be the gold standard within the local community of growers of both ganja and other items, it usually adjusts itself to pH 6.5-7 and stays there.

Yes I know I should've used Perlite and preferably some kind of clay or even sand, but I did not and still do not have access to it, used it on previous grows to good success.

Humidity: RH at 25-30% roughly.

400W HPS, the canopy is far from the lightsource.

Temperatures are decent, 27c/80f.

Pot size: 3 Gallon

Neutrients used (2 feedings, not consecutive feedings, water in between);
Hesi Root Complex
Hesi SuperVit
Hesi Powerzyme
Hesi TNT Complex
Hesi Bloom Complex (Running out of N on one plant)

Watering have been every other day, let it dry a bit, soak the roots, tapwater is pH 7.5-8. (pH down have been procured).

Runoff water have been tested at pH 6.

No pests have been found.

I've added crushed and slightly roasted 6 eggshells total and added to the top of the soil of every plant today to counteract calcium deficency, picture added of said crushed eggshells.

Alright, with that out of the way let's get to the pictures, they are of 2 plants, I have three other that are similarly affected but these two are the worst hit and as such, best for diagnosis, a Reserva Privada OG#18 and a Kali Mist (might be Western Winds, no practical difference).

Here comes first 10 pictures, 1 of the eggshells, I know there's a 10 message limit to each post, so I'll have a followup post with the last ones.

And let's have a few more pictures shall we?

Forgot to add! The reason they look so droopy in the pictures are due to the fact these were all taken before their feeding today, which was the second round of neutrients, they've perked up quite nicely now.

dont water every other day if there not drying out, they need a wet dry cycle. How long have they been in the 3 gallon pots? Do you have a ppm pen ?

Hi Booms, I do only water then when they've dried out, as can be seen on the pictures above, and they've been in the 3 gallon pots for about 2 weeks, no I do not have a PPM pen.

HOWEVER, after a sudden realization I've found out that I've dosed all my neutrients, Hesi and otherwise at 1/10'th strength, 10% god damn fucking percent, I had my measurements mixed up all this time, where the schedule said 50ml I've put 5, where it was 20 I've put 2, for the love of god, I feel so stupid, so I suppose these are deficencies all around, I've mixed up another 3 gallon bucket with proper 100% feeding strength.

If your soil is so good, why the problem? A good soil needs no nutes added for the first month of use. Blaming your nute strength is not the issue you need to tackle. Either your soil is off or your water qualilty is poor.

Telling us what soil is to "revealing" is kinda dumb! Revealing of what "secret"? LOL

BTW, you only need to use the ROOTS every 3rd or 4th feeding! HESI gave that info out to large scale (commercial) users last year. The Power Clean (zyme) should be every other or every 3rd feeding. Same info as above.....That'll save you some coins down the road.
Swap a liquid Kelp out for the Super Vit and save on that overpriced item too....Better yet, if you can get it over there,,,Sea Green!

The Bloom is higher in P and K and you DON'T need that in veg!
