Battling the initial soil setup.

LED's 3000k, 320w 3 per 4x8

LED's 3000k, 320w 3 per 4x8

Figured.
For some reason LED’s seem to cause mag deficiencies.
No hard evidence, but a good bit of anecdotal discussion if you google it.
Some discussion on the LED sub forum.


I basically ignored it. Moved my lights up, added deep red which may have helped.

Yah know... I have read that same anecdotal evidence on reddit a few places and others online. Maybe it is somehow true? What could cause this... I will need to re-read all of magnesiums roles. Hmm... So theres a chance the LED's make the cal and mag go out of wack or be in more demand... This is interesting.

I agree with Rico Fermented Plant Juice is great stuff, and all natural. I am looking for some of the Boking 14 Comfrey is the best cut and drop also you can use a white clover cover crop. Just my 2 cents.

 

[CodyPomeray]

12 boking 14 cuts bought will figure out cloning them down this winter and get ready for spring. Good tip! Been using white and red clover for years, this year switched over to a 14 sprout blend, seems great so far. The mg issue is subsiding a bit, still see some Ca issues. Going to top dress a bit of stuff tonight and see how it goes.

I don’t want to put out false information, but I am getting more and more convinced the lights are causing it. Your plants look like mine will. I’m not convinced it’s an actual deficiency. More of a transference problem. The plants are perfectly healthy, except for color.

Trying to read through this now...but rough hypothesis.

Led's emit a spectrum of light different than HPS, and therefore push the plants to need more Ca and Mg than normal.

 

[h.h.]

I read the abstracts and the conclusions. I may skim the text for any obvious inaccuracies. Much is often research. I don’t try to understand it all. Just what suits my needs or sparks my interest.

Like you said, “rough”. No conclusion. I’ll take a second look at it later on.

 

[Rico Swazi]

I mulched my outdoors plants all year with comfrey and had very dense buds, much denser than normal which I believe was from the potassium.

Comfrey and nettle have replaced any alfalfa I used to buy
those along with intercropping legumes and grains has shown me how little nitrates are needed for my particular soil to produce healthy food and herb


I believe the real magic of comfrey, for lack of a better term, is the microbial breakdown of the leaves which in turn helps to foster healthy microbe populations in the rhizosphere

Hope your plants are doing better
pics would be nice and I know you stated you cant remember exactly what is in it, but a description of your soil mix to the best of your memory would be helpful


interesting about the led lighting changing nutrient uptake

 

[CodyPomeray]

kelp meal, crab meal, fish bone meal, alfala meal, worm castings, compost from my pit, oyster shell, glacial rock dusts, gypsum, guano, diatomacious earth, little magnesium sulfate mixed into pure coco, and promix 4 and roots 707 mix. Flipped and cooked for a month almost.

I think I forgot dolomite and a few other things, but not sure. I kinda just went in and bought everything i remembered.

Plants are looking a bit better and a bit worse in ways. I think I am dealign with a bit of light burn from the LED's, someone confirm? Yellowing on the tips there.

These things are still demanding so much cal mag, more than I am used to. I got a heavier watering to do tonight with 90ml instead of 70ml of calmag. Maybe it will help. I top dressed mocha bat guano and some EWC on the last watering, that will be breaking down over the coming weeks and helping out as we move to flower.

Overall, they are growing, cant complain, but they need some help. I need to read more but that paper I linked, in my uneducated reading of it, said certain spectrums make calcium in more demand (i think)

I will need to reread that paper and look into magnesium.

**Edit** Water is generally 6.3-6.8 when I check. I try to not add too much ph up or ph down as I assume it will fuck up the mykos, azos and recharge.

 

[bsgospel]

For once I have a suggestion that isn't calcium. Too much Mg, not enough K. Your P and Ca are well represented. Micros might be conspiring, waiting for a drop in pH.

 

[CodyPomeray]

What should my water be ph'd at? I know in proper organic soil it doesnt matter, but wondering If I am being too aggressive around the 6.8 mark. Too much mg you say eh? Interesting...

 

[gardener60]

There are numerous growers that ph around 6.8. I think that is because of the strain. 6.2-6.5 keeps you in the ball game. Consider using epsom salt I read some where it is not really a salt. I have to research this again. Epsom salt was named for a bitter saline spring at Epsom in Surrey, England. It is one of many naturally occurring mineral salts, a compound of magnesium and sulfate. Just my 2 cents.

mykos, azos and recharge ... oh my!
throw in some big bloom, cal mag and pH fixation with up and down and it is no wonder you are battling, chasing your tail on this one


I suggest a grow with your home grown worm casting/compost and very little else.

Start there and then add store bought 'things' (if necessary)
That will give you a good idea of where you are throwing your money away




I didn't see any mulch on top of your soil, other than the start of a living mulch? crushed leaves from your yard would work nicely , worms love them and they can provide some nutrients like calcium and potassium (species dependent) but is not to be relied upon for that purpose. Mulch shades the soil keeping it moist so the worms work near the surface and feeder roots.







hoping you win the battle my friend
