Let's see and hear about your sick plants!!

[Dbelle]

Hi how's it going? Maybe you can help me figure this one out? Im getting purple-ish growth coming out of new shoots. Try and bear with me as I give as many details as I can.... I just brought a few plants out from indoors. I let them get adjusted to the sunlight for about 5 days or so, I then transplanted them to larger containers. They got a little droopiness to them, along with the purple-ish new growth, as you can see from the pictures. However, I did the same process to some more plants of the same strain, a few weeks earlier. The plants that came outside first, do not have the purple-ness or the droopyness. So what's the deal? The droopiness kind of looks like over watering, but none of the other plants have these effects even though they get the same watering. Is it Lightstress from the sun? If it is why would the other plants of the same strain adjust almost twice as fast? Is it nutrient problems? They all got the same exact mix, except for one difference....The affected plants got pelletized lime instead of dolomite lime. However, I added a bit more azomite with the pelletized lime for that Mg. Ok so I think that covers with. What do you think?

I have seen some very bad experiences with Azomite. Has more than 10% aluminum which they say is not available to the plant, yet, all the good elements they are are available to the plant. I think the stuff is toxic personally.

Magnesium from Dolomite will take forever to become available and you really don't need a lot of magnesium provided you have phosphorus high enough, which I would bet you need from the color of things and what looks like low energy....

 

[Dbelle]

I doubt it has anything to do with aluminum. The Down To Earth brand azomite I used doesn't list aluminum as a component. Also all the plants mixed with the dolomite lime are actually doing great. They aren't the ones that are droopy with purple new growth. So thats why I mentioned it might be something to do with the pelletized lime and the fact that, that kind of lime does not contain any magnesium. I also don't see how it could be a magnesium problem. Im just trying to think of everything. Maybe a phosphorus thing? There's definately enough of it in there, all the other plants that be been out here since may are doing great, great colors, great growth. Do you think it might be a lack of microbes to break down the amendments? Maybe I'll hit the new ladies with some tea. Now that I think about it, I'm not sure if I gave them any. What do you mean by low energy?

Azomite is mined. Read the analysis yourself. Twisted new leaves is usually calcium. Aluminum kills root tips. Calcium is only picked up by the root tips. See if the roots are white or brown and whether the tips are alive or not. I doubt the pelletized lime is working yet. The calcium in the dolomite is probably saving you. Probably a finer grind? Magnesium deficiency doesn't show itself on newer leaves. And usually Mg deficiency is due to lack of phosphorus or too much potassium. A lot of research shows that high Mg lowers THC.

Read up about ATP in the plant. Note that it is made up 3 phosphates, NH2, CH2 and O. It is the energy molecule. No K, no Mg, no Ca in ATP.....

 

[Dbelle]

That's interesting, I didn't realize that azomite was made up of all those elements, thanks for that link.

The dolomite was pretty much the same as the pelletized lime, it wasn't a powder or anything.

I don't think it's a magnesium deficiency either. As for P and K, the problem plants have the same amounts of P and K as the ones without problems. The only difference is the type of lime and the small amount of azomite. It doesn't really look like any P or K deficiency. Maybe I'm wrong though.

There's no twisting new leaves just some droopiness that looks like over watering and the purple-ish of the new shoots.

I've read up on atp years back when I got into all this. I got a intro to botany textbook laying around here somewhere, only got through the first few chapters I think.

 

[slownickel]

Pretty sure those new leaves that are twisting are suffering from calcium deficiency.

 

[Dbelle]

Ok so based on what I've told you so far, how would I fix the calcium deficiency? Thanks for your input by the way.

Not sure what you are using for a medium. Is this hydroponics? Medium?

I would try some calcium nitrate, that gives a very quick response.

looks like sulfur and maybe iron def. based on what you've said so far i would wait a few days for the plants to dry up some and get used to the new pots. water them sparingly till they start greening back up again before you resume full watering and feedings.

looks like transplant shocked em and overwater/under oxygenation.

just give em some time to dry out and catch up, you\ll be alright.

After seeing photos of couple of OG clones I feel better. Apparently this plant is susceptible to mosaic (for all you tobacco smokers beware) and I wanted to see if anyone had that experience or not as I plan to clone her. Interestingly enough, only a couple of branches demonstrate this trait.

I do not know of any deficiencies that hit the vein in a mottled fashion.

i've grown in the harshest (hardest?) conditions since my first day growing. i've never had anywhere near 1/10th of all these fairies and phantoms that seem to plague everyone else gardens. i'm talking all bagseed for the most part, random seeds from random plants.

never seen any broad mites, never seen any russet mites, never had any dudding, never had any TMV, nothing special or fancy. most i've run across are fungus gnats, spider mites (the worst mites of all really) thrips, ants, aphids, had a leaf hopper, some slugs and snails going to work on some of my outdoor as well as caterpillars and nematodes that kill seeds before they even emerge from the shell.

all of it can be recovered from. well all of that i said. never had any of those daemons and faeries plague my grows though. no clue how to fix those. but all the other shit i've run across you can fix relatively easy. the hardest thing i've had to get rid of are spidermites.

My first thoughts were some type of shock from the environment change. I've just never seen em turn that color, so I figured I'd make my first ever forum post since i been reading this forum for years, and see what other people think. Also, this is my first outdoor grow, so I'm just being extra cautious. Thanks.

It's peat, coco, and a bit of soil. Thanks for the advice, im gonna go read up on calcium nitrate and if things don't turn around in a few days, I might hit em with some of that.

Interestingly, I have a few plants of this same strain that are outside, waiting to be transplanted into the new pots and they are doing fine. So I'm starting to think that this particular strain is not liking something in my outdoor mix. Oh well, I'm not too worried though. Thanks.

Do you have a soil analysis? If you haven't included the right amount of calcium in your mix, this will hurt the grow. Peat is extremely acid and gives off a lot of potassium (azomite will liberate aluminum quickly in an acid pH). Without a good soil analysis, you are working with your eyes closed.

 

[Chunkypigs]

when I move plants outside this often happens, but I never see bugs. usually just happens to the top layer of the plant then it grows out normal again.

this plant is getting it worse than most with no sign of getting normal again after 4 weeks.
it's in a location that just gets partial sun at the edge of the forest.

chop all those damaged leaves off. the plant is trying to hold on to them and they do not do anything with all those holes in them.

looks like when you put them outside the sun is so intense compared to what was going on before that the leaves start to grow bigger. but since they don't have enough roots to support that rapid growth you get micro deficiencies. my opinion based on similar damage on other plants.

but at any rate whether or not you accept my diagnosis you need to get rid of those leaves so she can grow new ones.

Well the soil is just regular roots organic, I'm sure it's fine I use it all the time. The mix for the outdoors is a mix I got off a thread from this site. It's doing great for the plants.

Anyway, since I originally posted the plants are starting to do better. It must've been the sudden change in weather and light.

Honestly dude, I usually just use straight peat and soil 50/50, with a little bit of lime, some perlite, and I never had a problem with acidity or deficiencies. Ive heard that after a while peat starts to break down and become more acidic. But I've never had this problem.

Thanks for the suggestions.

What I think (and hope) is all Larry og

Ok. It's still happening to me I have them in roots organic coco/ soil, only a bit of veg nutes. Then into flower. They get a quarter
Cup of maxi bloom and 5oz calmag and every fourth watering a quarter cup of gen Organics bloom. Alternate with a 5oz calmag only watering. In a 55 g drum.

I thought it was overfert with the first run. Now I'm Not going over .9 EC. Runoff is 1.3

Bottom leaves turn yellow then crispy then dead. From the bottom up. Only certain plants.

Wtf?!?!

 

[slownickel]

Chunky, that is referred to as shot leaf. Pretty particular to cannabis. Seems like heavy potassium or magnesium causes it.
