Hi buddies! Hope you all right. Im breaking my head trying to guess whats happening to some of my girls. Problems become harder to guess when i try to contrast information with the grow store guy and an experienced friend...

Some plants started to sprout them new leaves in a light green / yellowish colour, usually that lime green golour is normal in new leaves and becomes darkers as the leaves grows, but this was not the case.

First of all symptoms appeared in some Bodhi Seeds Lemon Lotus i germinated a month and a half or so with no problems, from yoghurt pots 10 days later they went to 3litre pots with fresh new soil (Canna Professional + light mix), while in the 3 litre pot i topped them and prunned them in terms of open the plants and make a kind of bush structure. After the second prune and shibari them they grew for a couple days and then looked like stop growing. the new set of leaves started to grow more yellow than normal, i thought that this couldnt be a lack of nitrogen cause its a mobile nutrient and it will start in the bottom part of the plant, but botton fan leaves looked like a bit more pale than 2 days ago, so i decide to give them so Bio Vega (Grow fertilizer) in a 350ppm dose. (Small dose, I start with R/O water, Cal/MAG till 200ppm and then put the feeds on it.) But the next they they still blocked. Then i though it could be a lack of micro or quelates, so i sprayed and water them some Bio Vera (Aloe Vera with Molibdene, Manganesum, Iron... blabla). Nothing happened in the next days, except some plants from clone started to show the same palish colour in the upper leaves. They were in 3litre pots for 20 days, so i decided to transplant them 5 days ago to a 11 litre (3gal) pot with fresh new soil with some food on it (All mix from Biobizz), watered them with somo H&G Roots Excelurator (Root Stimulator) and they still block, not growing, not yellowing more at all (or at least way slow), alive, not drying the soil at all (thing thats make me think they are block, but why? Looking for info the most closer thing is a lack of iron but how and why? Never had this problem and im always using the same method, never had lack of iron in any of my plants.

I phone called a friend and i told him whats happening and he told me the same, looks like lack of iron. Im not 100% sure. So yesterday i sprayed again with some Phosphoric Soap as a soaking agent and some Acti Vera as Quelates. Went to the local Grow Shop to show some pics to the guy from the store asking for help and he started to ask me set up and temps question... bla bla..., everything is on fleek except the fact that i water little water for so many plants and they never have all the medium wet at all so they can't eat all the food from the soil. (I repeat, always watered like this and never had problems, but gonna start to water more.) So he guess the problem comes from here and thats all, he recomends me to use some Formulex via foliar spray today, and another application three days later. okay so i did formulex spray today, gonna wait till tomorrow but plants look exactly the same.

This is Formulex:

N - 2,29%.
P - 0,87%.
K - 3,36%.
Ca - 1,85%.
Cu - 0,002%.
I - 0,040%.
Mn - 0,010%.
Mo - 0,001%.
Zn - 0,0025%.


This is Acti Vera

Mg - 0.01%
Cu - 30mg/kg
Mn - 321mg/kg
Zn - 70mg/kg
I - 3420mg/kg
B - 191mg/kg
Mo - 30mg/kg
Ph - 4.15

I absolutely spray lights off.

Okey so, there's some data of what im using and room temps and the steps i did for the last 3 weeks etc.

Temps Min 20ºC
Temps Max 28ºC
Temp Media 24ºC/25ºC

RH Min 50%
RH Max 80%

Fans are working all day, room feels right, not so cool, not so hot and you can breath in perfectly.

I used Extreme Gardening Azos and Mykos for transplanting to the the 3 litre pot with Canna Porfessional Soil Light Mix

I water with R/O Water, Cal Mag till 200ppm/400us, H&G Roots Excelurator, Atami B'cuzz Silica Boost and Ph 6.0-6.5 always.

I did a couple waterings with Xtreme Gardening Tea Brew (Kelp, Humic Acids, Compost and Earthworm castings.) This is bubbled with airstones for 48 hours and dilutted 1 litre for every gallon.

I did one watering and one foliar spray with Acti Vera.

I did one feeding day to all the plants with 350ppm and other feed day to the Lemon Lotus aswell (The most poor looking of them all) with another 350ppm. (350 is the total ppm i got Mixing Canna Bio Vega (grow fertilizer), Roots, Silica Boost and Cal/Mag)

If i need to add Ph + or Ph - they are always from organic sources.

I always measure my Ph and Ec

I did watered so little water, 21 litres for 70 plants every other day. I didn't let them dry at all (don't let the plant dehidrate), but try to keep the soil moist but not super heavy watered. I always did like this.

All my other plants, the ones that are not showing this syptoms, looks fucking perfect, the ones that look bad they all look like afected by the same lack/excess/virus/fungus/microbe/whatever shit it is...

First gonna show you how they looked the first week in the 3 litre fresh new soil pot with azos and mykos. (3 weeks ago aprox)

Okey then they grew for 4 days or so and then stopped growing fast, slowered grow af and started to yellow in the new sprouts. I got no pics for the next weeks except just after the transplant. But now you can notice the pale colour. Gonna share some pics with natural light and some under MH.

This is Lemon Lotus next to a healthy plant just for compare the colours.

The Last pics are some clones that also started to look palish and yellowing at the upper part, from top to the bottom

They are Rez's Sour Diesel "RIRI" cut. What the fuck, SOUR DIESEL? PALE GREEN? Of curse is not genetic related and of course they need something extra or something less... I had never seen my plants doing this, not from seed, not my own selections, nor selected cuts like riri.

Fuck i feel like a fucking murderer when my plants looks like this.

Whats happening? You all know how a Sour Diesel's Green Colour should look like, it's not supossed to be like this... :( :(

Hope they recovery pretty soon, stopped watering them 3 days ago so i can wait the medium is dry. But still moist.

The way the yellow starts at the bottom and works up reminds me of just a nitrogen deficiency, but I have no idea why a strain you've been running already would suddenly show a shortage. And you can edit in 3 more posts once you hit 50. Hopefully somebody with more experience can tell you what's up.

MrGanjaMan

I heard that if you do not saturate you soil each time you water, that you could run into iron deficiencies.
Maybe chronic underwatering is your problem.
 

AgentPothead

I don't think it's iron because iron tends to show in the newest growth, ie the middles of the top leaves. These seem to be yellowing bottom up, which implies it's using up the nutrient from the older leaves.

Thanks buddies for answering so fast, hope we can get to a conclussion and save my babes.

No no, the yellowing started in the newest leaves, in the upper part of each stem, then the plant became yellow on the lowest part, i guess because its blocked and obviously cant use or metabolize nitrogen.



I heard that if you do not saturate you soil each time you water, that you could run into iron deficiencies.

That could be a possibility, but i never had this problem before and i use the same ammount of water always, more or less.

But yeah, in this moment is the most possible answer if its not a toxicity/fungal/sickness problem.

Just this guy, ya know?
I dunno man, iron tends to be the freshest new growth, not an entire leaf at a time like that. And I'm not seeing the darker green middles like it would be if it was late stage iron. But hopefully somebody who does this more can chime in :)

Yes, you are absolutely right in this, thats the only thing that makes me doubt about the lack of iron. Theres no green in the entire leafs, not even in the middle, all of them are yellow entirely.

Cold roots. Cold will cause all kinds of lockouts.

They need to be off the floor for at least an inch (like on top of a folded crate). The floor is too efficient in conducting cold to the pots, especially indoors where they're not heated by the sun.

I grow outdoors in the stuff you walk on and amend it with Animal manures. Your way seems so complicated. Lots of parts to keep together.


Tanzanian Magic has a good idea ... and I see yr big pots are dry. Whomever (above) said you've got to water more may be correct. I always water on a goodly amount thinking that the water has the extra task of taking oxygen to the roots. (Like, the water displaces air around the roots. As the water flows thru it draws new air, and thus fresh oxygen, around the roots).
Watering like this will flush out excess minerals too. I think maybe you also have a mineral imbalance caused by buildup ... no matter if yr pH says all ok.


Hope you are successful ...

Hi my friend, thanks for you time and answer.
I don't think this could be an option since I'm growing and flowering in the same place 3 years ago, never had a problem for low Temps, nor in the roots. Also, this winter is beign hotter than last years, not very cold yet don't know why.



You sprayed them with that foliar spray today? It will take a day or three to show any changes I'm guessing.

Yep, yesterday with Acti Vera and Today with Formulex, both days with Phosphatic Soap as a soaking agent. All other plants looking pretty happy! Will see how the poor ones develope and will spray them with formulex in the next three days.

Regards.

Thanks for the answer!

Yess you are right, every run I do I realise that less. Is more. Yeah if you take a look to the under rh pics you can see that lemon lotus (the more yellowish) are dry, that's because I'm letting them dry out before I water them again, because they are blocked and can't absorb anything, and that's why I'm foliar spraying them, I spect tomorrow or past tomorrow to water them again. The other ones as you can see like Riri are little bit moist, I watered all them except lemon lotus yesterday (50 plants in 3 gal no counting lemon lotus) with 42 litre water. I can't get enough, but they looked pretty happy today, past tomorrow I'm planning on water them again 56 plants with 62 litre or a little bit more, you guys think it's enough?

Thanks for the info, I'm always afraid of overwatering, but I'm gonna be afraid of under watering as well since today.

Regards.

I had the exact same problem, and your plants looks exactly like some of mine...
It turned out that for some reason the soil I bought didn't pass any quality inspection and some bags were poorly mixed with lots of shitty hot compost that first gave me some sign of K toxicity and then I had a huge PH drop in the soil

I fixed it adding PH up to the water, watering with ph 7 water and keep the nutes in the right PH range made them green up and completely healthy...

hope this will work for you....
Check the PH of soil...

I'm going to say a sulphur deficiency mixed with a nitrogen deficiency. You need to water water them well. To treat the sulphur problem get some epsom salts and give the plants 2 maybe 3 sprays over 7 days. Epsom salts are pure magnesium sulphate, great for treating sulphur and magnesium problems.

Well if you try this for a few plants, you can find out. If you place 5 plants on a folded crate, and they improve, you'll know what is/isn't the cause.

And it doesn't need to be more than one or two inches, it's the ground that is conducting the cold like a copper wire can conduct electricity.
