I heard the term hypocalcemia, but forget what I read at the time.


I found this helpful chart...

I believe that you are supposed to flick and squeeze your plant to see if it contracts, to test for hypocalcemia. 😁

I think I had this at school. Every time my french teacher poked her finger at my temple, my eyebrows contracted. Is there an audible connection to the term 'you boy' ? :)

They seem to of turned a corner. You did something right, or the size of them is giving them a bit more localised humidity. Many of my struggles revolve around little plants in big spaces, and vanish once they start touching.

I heard the term hypocalcemia, but forget what I read at the time. My thread, if I get it up, is just some pics and ideas, to see how others feel about it. I know now what you will say I think :)


I don't get my PPM numbers from a meter (meters give EC). PPM is calculated based on mixing ratios. I guess your biobizz is about 5% calcium as CaO which is 3.6% as elemental calcium (without the O bit, or Oxygen/oxidised). If you put 1ml of 3.6% in a liter, you get 36 PPM. I'm not really calculating anything here, it's just moving the decimal point. 5-6ml you say? That's the best part of 200PPM then. I have seen people hitting such numbers, but it's some way above last years survey average of 91 PPM.
The real issue is the N quantity that calmag likely has listed. Is it about 3%?
Do the math with me.. 1ml of 3% in a liter, is 30PPM. You might of been sticking in 180 PPM of Nitrogen. That's some heavy hitting.

I feel you bro, in everything you said.
Yeah, the first change in how i managed the environment was the first foward step. And like you said when i increased the light power they got worst, add to much water (in reality was just a big watering to saturate the pot and see for the first time its weigth and feel) and they got worst..
They got better after the huge dose of calmag, (i know i know about the huge nitrogen spike and its problems in flowering, but they need it bad for the flowering stage and i dont have anything else and pretty much everything i find have nitrogen in it) but also raised the light in heigth a bit and and tried lower wattages at the time, combine that with foliars of silicon, seaweed, potassic soap and the talked pinch of calmag and something must have made them feel better, in the case of the worst one.
Also with so much calmag i tried to somehow make some of it holds for a bit more time in the soil, i think my newb mind is thinking somehow well?

I tried to find more specific information about the calmag and didnt find it, even foliar measuments i didnt properly find so i went with good sense and use that pinch of it. I can only contact them directly and ask.

For example today right before ligths out, they are droped, the Mazarilla is even more than yesterday and the Killer. Major difference in both comparing to the worst and flowering one, they were much ligther, i point at half the weight from when i saturated the soil and now im wondering, they are bigger and entering the stretch stage, transpiring more, rh at around 50/55% to promote more root uptake, the difference from the weight from yesterday to today is drastic and i feel it imediatly, i guess they must need watering. The Gorilla is still quite heavy, and they all got the same ammount of water.

I was wondering if i should water them and as im writing this i came to the conclusion that i will water them but since the soils are moist, im going to bottom water them around 5 or 10% of the total ammount of liters of the pots, if tomorrow i feel they drinked it all, i will bottom water them again, until i see they need even more, or less, i did this in when i got the RA, a good moist soil promotes them but also promotes good roots and grow so i will try this "pulse" method.

Btw, the link to where i read about the Hypocalcemia, sorry if i shouldnt do this, if so please delete it

i tried the suggested apps.
Some stranges readings like the results not changing at the same distance but dimming down the light. Close readings comparing with the results that Mars provide, but now how i translate this to actual grow?
So, i choosed that spectrum because is what i feel is more comparable to this light
Right as they are, around 70~76cm distance and power at 60/65%, right beside the Gorila

30cm distance like Mars guidelines and in the middle but at my powet of 65%

So if i will take the phone app into consideration (i think i could calibrate it according the above Mars maps) i gave them too much light in the start, the Killer and the Mazarilla are receiving a bit too much wich i kinda agree and the Gorila should be happy but she is the saddest for now (since sprouting).

Maybe with some days of proper distance and power they all recover and shifts for the better?

Before lights out

Tomorrow i will try to calibrate the best with the Mars chart and see what i get but for now, taking the apps with a pinch of salt, anyone opinions?

Well, since i feel the force that the plants applys in the droopes lwafs stems when i raise them up, i guess why can say that they are contracting?:D
We are joking but who knows

Set it to high cri 3000 led and set the number of hours lights are on. Those readings you posted are way too high.
Take any claims with salt, especially Mars.

Will do mr dots, the hours i already did it but will measure with the 3000k spec and post what i got later..

Meanwhile the Killer in the left back and the Mazarilla in the front right seems to have take good the yesterday watering, but the killer is showing me show white tips in the new growth at the cannopy.

What do you mean?
She looks fine to me.

The leaves might be a little pale, but they look healthy.

It could be some light bleaching or nutrition issue, but I don't think that it's anything to worry about.
She'll grow into it.

She just needs lots of LITFA...

This is my seedling...

And two seconds later from a different angle...


IMG_20220130_233603.jpg



I've always found the first set of leaves to be a lighter green than the cotyledons and the camera angle and lighting makes a huge difference in the way the plant looks.

The dark green cotyledons means that she isn't pulling nutrients from them, so I think your baby is just fine.

I think that's a good idea.

I downloaded the app and compared it to my lux meter.

I had to reduce the app calibration by 49% to get the same reading as my lux meter. That's Huge !!

I would think that calibrating your app using the Mars numbers is a good idea.

They should be a lot more accurate than an uncalibrated phone app.

Be very careful with that hypocalcemia stuff. That guy moves forum to forum getting banned. I spotted he was back yesterday, with just one of his 8 posts not attacking someone with different beliefs. I'm not sure hypocalcemia even exists in plants, and my search engine wasn't sure either. Some of the pics used there were posted here when he didn't have a clue, but was impossible to talk to. As he has moved forum to forum he has left a wake of bad posts behind him, unable to correct them due to post bans and outright bans. He currently thinks it's Boron. Something he did speak of in that thread. You can see the cogs going round in his head, as you see him go around the internet. I said repeatedly it's P, which is still swimming around in his thoughts, being seen on his plants, but denied as the problem. As yet, he has never shown a decent plant. The one pic of a fixed plant, is very suspicious. It's a side by side, perhaps not a day apart, but at different levels of illumination and each side of a feed. It's not conclusive of anything

Thanks on the advice bro, i taked that with a pinch of salt like some things. I didnt take properly seriously because like you i didnt find much about it online.

I guess is one of those cases where someone speaks in a way that looks inteligent and knowledgable of something when in fact is not

Exactly that, that paleness and since she is 3 days old and pretty small. That paleness is strange because the leafs look darker in the middle and paller on the outside and i was expecting a bit of more rapid growth. She is dommed, rh is around 65/75 most of the time, temps like the tent. The dome is not 100% clear so i dont think is too much light. The soil is not so moist so i guess maynr is something ph related or something like that

Today, the Gorila on the back right looks better than yesterday, it doesnt seems so crashed, is droopy, and the leafs appear to be kinda funky still, but is more perky than the past days, the stems are not clawing, also still no resin in her, even whenni rub the fingers i just feel the slightest tiny bit of stikiness and the i notice the popcorns are fattening up slightly every day
20220131_235920.jpg
20220201_000441.jpg

The Killer on the back left reached the height of the Gorilla and will be taller, the leafs are more drooped than the earlier in the day, but looks good appart of those slight burned tips. I didnt cliped the single first leaf and is still there, rubbing the perlite, matter of fact i thought that all the close to the soil leafs of all the girls would be bad because of the waterings, they didnt.

The Rocky in the front left, is not clawing so much so she got out of that overwater and looks good, she didnt perk up alot today neither drooped a lot, either way she is not 100% happy.

Incredible enough the Mazarilla in the front right, is more drooped than yesterday and is more drooped than the sad Gorila, maybe she didnt like the watering yesterday, wich was not alot, just around 800ml of water but i guess is a bit of too much and to close to the previous one because some of the roots that i was seeing in the bottom of the pot browned up, but they also shriveled and now im in the limbo of if its because of too much water and they drowned or because of the direct contact with the dry air, by how she looks, i guess is the first one and i know that this girl is prone to mold in flowering because i have it when i grow her in the same pot along with a Killer, only her got mold, and the killer in that grow taked overwatering better than her and in this grow seems the same, also they look consistent overall from one grow to another, props to you and your good seeds my friend.
20220131_235913.jpg

Today i manage to have a better environment inside the dome of the coco experiment. Always above 65% maxing out at 75~80% and i get a surprise now in the end of the day, she is praying, also she greened up that paleness to what it seems a more healthy green, she is not stretching much so i guess what i did today will be done tomorrow and maintain it until she can support better the lower rh of the tent. The temps dont drop like in the tent and they seem to be a constant of around 24. I will leave the seed attached, it will be fun if the cotylodons hold up until later stages like the other girls (still green except for the Gorila) and see the shell still there :D
BUT I NEED HELP WITH HER, anyone have opinions what could be those yellow tips on the serrations? The strange thing is i only noticed them now that she greened up a bit :confused:, or im just "stressin" up and it is probably nothing?

............. Mr. Dots, i followed your advice and changed the spectrum to high cri 3000k, the hours were already adjusted.
Indeed the results are lower and seem more realistic

Any considerations?

At 30 cm from the light like the Mars guideline power 65%
Screenshot_20220131-235829_PPFD Meter.jpg


At the Gorila heigth (right back) to the middle of the tent, i guess you get the idea, distance of thw light is around 70cm
Screenshot_20220131-235800_PPFD Meter.jpg


At the coco experiment wich is around 90cm or a bit more from the light
Screenshot_20220201-001133_PPFD Meter.jpg

I know in the meantime i raised the light distance, over water them a bit, etc etc but with how much salt i can take this into consideration?
The Gorilla is in full flower mode, wich can hold much more light, and indeed she seems to be slowly recovering after i raised the light. But at the same time the Mazarilla and Killer that are in late veg early flowering stretch maybe should be happier, and maybe stretching a bit lacking a bit of light? And the Rocky that is further away after get 100% of the overwatering should i expect some stretch reaching to the light?

I know its a guideline, but what you and others think?

It was a very convincing post. No hint of being anything other than a professor until some way through it, when he questions himself. Then returns to form at the very end, with some 'everyone is keeping the truth from us, only I know now' stuff.
It's the guy I called in, but I guess he's on a post ban.
This is the thread where it all started. The pics are there in post #1 https://www.icmag.com/forum/marijua...led-deficiency-before-it-takes-over-the-world
Perhaps the most banned person on the internet. His last thread of note was his new extraction technique, making a product he wouldn't show, using a technique too dangerous to share. He has had a number of bans since then though.
CosmicGiggle calls him Drew, after his Drewsif account.

to be honest in my grow
everytime i raised the light the plants near enough overnight stretched up to it
my tallest plant is now at 45" and 5" from the light at 100%
it spent its life in the middle of the tent in the sweet spot so that may have contibuted to the extra growth
its growth is excellent with no bleaching
you could be having problems with watering as i found without the heat of the hps the pots dont dry out the same
i still struggle with balancing this(but then i am still a nube myself)
i took these pics just now for this post

sorry about quality its lights out and i just used my phone
but it lets you see what i mean
these are at 64 days from seed 12/12
as different strains they will grow to different hieghts but i think they have a good bit of stretching yet
they look excellent so far
i like the app whats it called?
hope the ganja gods watch over you
