deficiency or heat stress

Temps during the last few daytime hours of the last few days have been in the lower 90s while the humidity is consistently in 25-30 range. Completely organic soil containing FFOF, dolomite lime, N bat Guano, alfalfa, kelp, feather meal, oyster shell crushed and flour,coco, perlite, high P fish bone meal, Organicare Pure, azomite, chicken compost, ewc, and greensand. I saturate with almost every watering to keep the root zone nice and cool. I'm getting pretty vigorous growth shoots still which leads me to believe it's potassium related? It looks like it could be magnesium maybe? Any input would make a world of difference as I'm not very good at diagnoses. First two pics: bc blueberry
Last pic: delicious black russian

I'm not seeing the classic heat stress signs of upward turned leaf tips/edges. Hard to believe you are deficient on anything given your recipe. So I would guess that something is locked out from an excess of something. Did you compost your mix for a couple months before using?

interesting prune-job.......a topiary :) goin' wit Bugeye here. that's no super soil, its.....Uber He-Man Soil. too mucha somethin' ............toxic in itself, or blocking uptake of another nute.

That's a deficiency. Looks like a Nitrogen deficiency in the first 2 but I'm not 100% I was just reading about this stuff last night. The last picture for sure looks like Magnesium deficiency.

Looks like high P.......How did you place the soil in the pot,,,,,straight mix? In alternating layers of your "hot" soil and a mild soil?

The N levels looks fine....

Hmm,,,,at what ratios did you add the Organicare (what one as Botanicare has this in several differing NPK ratio's?), High P bone meal, Chicken compost (whats the NPK of the chix comp?) and Guano (whats the NPK of the bat poop?)..???? Per cubic ft/how much?

I think your problem lies in your ratios.....

Read this link, it should help a little maybe?

I am using the rev tlo base mix without the use of blood meal or the soft rock phos. Exact recipe without those two things. Bat guano 10-1-1. I'll have to check the chicken compost. Soil cooked for 60+ days, kept moist, turned every other day.

until yer a SS expert, get your mix analyzed, or invest in a kit, imo.

Hmm,,, not all the information there is correct.....Not bad, but a cpl of things they say/show will simply create more problems.....The problems with user submitted information,,,same as here......I'm not perfect either.....so I don't supply broad across the board info posts on every problem you can encounter.

Can you tell me what is incorrect? Just so I can know for myself too. I like to read and do a lot of research and I thought it was pretty accurate but I'm no expert.

Rev's? I think you missed the layering part.....That's a hot soil you have there and I bet you used the high P Organicare too.
I would not have skipped the Soft rock phos.
Like the "Don" said...unless you know exactly what the npk's are of what your adding,,,,getting the soil analyzed is a safe way to go...

I also tend to see some pH trouble there,(squinting and shaking heat thoughtfully). Mmm maybe that's a low Mg problem in relation to everything going on......also.

SURE, np.

1: I find the color pH chart as misleading.....In hydro I have learned over the years that if I keep my swings between 5.8 and 6.2 that my hydro's do the best. I pH to 5.8 - 6.0 and let it go for 24 hrs....I feel that lower pH's are worse and effect the plant faster....I only run DWC in the colder months for fun and nutrient testing.
2: The big "low N" pic also shows high K.
3: P def,,,,purple stems can show P def,,,BUT many strains express a "purple" in the stems. Main and leaf. Not a reliable sign and should not have been listed first. Some strains do this with excess K and in the leaves too...The use of a high P like Peters (20-20-20) can, and will lead to overly high P problems!!!!! FAST.....correcting low P should be done with prudence and small steps.
4: The low K pic is good. This problem is sometimes mistaken for heat damage and over fertilization.
5: The Mg listing is good, but I don't like the leaf on the right in the first one....It has other problems going on there.
6: The Ca pics could have more as the ONE they have only shows one way a Ca def looks....(looks like the plant had mites too and that can appear like a Ca def to the unknowing).
7: The thing with micro nute problems are that they are kinda rare.....if your going to list them tell people. Have them more complete and show the stages of the problems development.....same goes for the macro's,,,show the stages!

Like I said,,,all in all it's not a bad posting, But sometimes these can be confusing to novice growers....
Example of: 98% of the time I see to much P as being called to little N.....usually from the use of high P bloom nutes. Adding more N will do nothing to solve that problem.....

I know, I'm a picky old bastard.....It comes with time "on the job" :wall:

Nice link though....It will help. :clap:

No, no, you're not a picky old bastard! I just love to learn as much as I can and I like to learn correct info from people that have been growing and know what they are talking about since I want to grow amazing :leaf:. So actually thank you for clearing that up cause you never know, I could need all this info someday :) Hopefully all this info helps Aleamoni as well!

hey bartender..............a one peat, a one perlite, a one poop.....................

some lime, some epsom salts and rock dust....... two feedings of bat-shit gravy during flower.
let it dry out between waterings, assure fresh air. start there, and then experiment and get fancy. I returned to easy-peasy organic every time. trouble-free grows are money in the bank. plant stress is what eats gear and profit, not low yields due to inadequate nutrition.

Could it be that they need a re pot to the next size? The reason they are hacked to shit is because I needed a ton of clones in a hurry for an experiment. They were quite a bit larger. The soil recipe isn't something I just cooked up, it's exactly as the rev gives in his book, I just left out the srp because imo the azomite is more than sufficient. I left out the blood meal because I find it hard to believe it's all organic given that it only comes from a few places as far as I understand. Anyhoo, I've used this soil for the clones I took weeks ago and they are just exploding
