What's up with those curved leaves though? Might be due to a nutrient deficiency, since they're growing in nothing but coco coir. My seedlings are growing in a mixture of coco coir, lava rocks, perlite and commercial potting soil for acid loving plants with added fertilizer. Therefore, I didn't have to feed them yet.
I had no problem acclimatizing them to ambient humidity. I removed the moist sphagnum moss when the seedlings had shed their seed coat. A couple of days later I would open up the plastic bag they were in, and seeing they didn't wilt I removed the entire bag shortly after.

Damn it I repotted my plants out of emergency as I think their soil situation was no good and they kinda need a reset for new roots to grow cause the pH/nutrition may not be helped, but they are having yellowing leaves and losing them..
It's like their babies that just keep crying, idk what they want
(Although i completely understand that repotting alone is plenty stressful)

A study was published a couple months ago that isolated DMT from Erythroxylum pungens, pretty interesting: https://www.ncbi.nlm.nih.gov/m/pubmed/30056276/

My plants have a few times dropped all their leaves and appeared dead, i just kept watering as needed and eventually they sprouted new leaves and are once again massive. I think it happened to ferrel as well a few months back.

Interesting, also the other alkaloids seem to be vasorelaxers.

Thanks yea it could always be that they go deciduous but it would be good to know hold mature plants need to be before they even do that (and under what conditions, and whether the leaves yellow before they fall in that case)... to help tell the difference between that and real problems.
At least one of the plants is growing new small leaves, I am not sure if that happens when they go deciduous - doesn't make sense to me.
Good to know to keep watering as needed. If it's really about nutrition and pH i may try azomite at some point.

Mine didnt go deciduous, i forgot to water them they dried up and all leaves died and fell off, ends of the branches shriveled up they looked done. After a few weeks though they came back.

That's exactly what happened to my bigger E. novogranatense plants about a week ago! Some of the leaves recovered though after a proper watering, but quite a few growth tips and leaves had shriveled and died. The next couple of days a lot more leaves fell of, but new ones are slowly appearing now so I'm sure the plants will bounce back.

yeah thats actually great, but how big are these plants we are talking about?
I trust that smallish seedlings are quite a bit more fragile and not really so built to go through something like that?

I had my Erythroxylum spp. plants go deciduous multiple times, even when they were rather small. Sadly I only started documenting their progress half a year ago. I did a little digging through my old pictures and posts, to hopefully give an insight in what going deciduous looks like, at least to my plants.
For example, this happened on the 21st of March to my E. novogranatense. You can clearly see the bigger leaves had turned yellow and were about to fall off. It's a very gradual process, and it seems to take forever for new leaves to start growing. However, my plants always come back with a vengeance, and get more bushy due to the growth of new side branches. It could be a nutrient issue, considering I only gave them worm castings sparingly. They would react positively to a fresh top dressing though, but it wouldn't speed up the recovery.

Giving them some homemade worm castings and acidifying the tap water made them a bit happier. They're still in regular commercial potting soil though.. One of my E. novogranatense dropped almost all of its leaves and is now slowly recovering. In the process it's pushing out new side shoots. The other one isn't actively growing at the moment and is losing some leaves as well. But they always recover and it's normally followed by a growth spurt.

On the 19th of June, those E. novogranatense plants had recovered. Now one of the E. coca decided to go deciduous.

Poison Drink said: I discovered the feared spider mites have reappeared in my grow tent. They were mainly affecting the E. novo's, hence the brown edges on some leaves. Already gave them their second dose of pyrethrum spray.. But they definitely like the warmer weather and higher humidity, since they keep on growing! The recent repotting might have a share in it too though. One of the E. coca's lost most of it's leaves but is now after a long time pushing out new growth. A reappearing phenomenon it seems..

And a couple of weeks ago they looked like this, before I forgot to water them in due time that is.

Looking nice man make sure you pluck a load of leaves, when you stress the plant like that the alkaloid production increases, and on the flip side if you dont pluck they will lose all their potency.

Any sources which confirm your thesis ? Especially the complete lost of potency.

Well I collected all the fallen leaves, but I treated the plants with pyrethrum a couple of times recently, so I'm unsure what to do with them. Also, some Erythroxylum spp. seedlings.

I thought pyrethrum was broken down by light in 48 hours. Thats pyrethrum though not permethrin or decamethrin or any of the other synthetic derivatives.

Stick them in your mouth and chew like a mother fucker would be my choice, or freeze them in a baggy and save up till you can do an extraction. Maybe a tea?

Well, then. I guess it's one of those often repeated myths like with the cuttings that can't be rooted. The increase of alkaloid production when plucking on a regular basis makes absolutely sense but I seriously doubt a total loss of potency in plants which never get harvested.
