Question What causes green leaves to fall off at a light touch?

Is there a deficiency that causes green leaves to fall off at a light touch? I was moving a plant out of my tent today and must have dropped 6 or 7 leaves between 4 plants. I wasn't being rough, separated all the branches before moving them, but they were dropping off. I reached back in to adjust a branch that was stuck and just my elbow touching a leaf on the way in caused it to fall off! These appear to be healthy, green leaves. I cannot find anything searching because it's just people talking about yellow leaves falling off during flower, which should happen, but green ones falling off at the slightest touch means something is wrong, at least to me. I grabbed a photo, but to me it just looks like leaves.

The stems appear to be white, but that is the flash reflecting back. If I don't use a flash it looks like I smeared vaseline on the lens.

Hmm, I'm growing in coco and have been doing 3-4 small waterings a day. If it is overwatering that seems odd, but odder things have happened.

Yeah.... honestly, I'm not sure what it could be? You seem like your the type to know if you were overwatering. It would have to be pretty wet. I've never grown in coco so I can't offer much more than a guess.

I'm sure others will chime in who will know better.

In the mean time....

How established are the plants root systems? Are they newly transplanted?

How's the humidity in your space? Is it excessively high or low?

The plants are very established, they are 1 auto and 3 I guess semi-autos who have been going since June and are flowering. 3 of the plants didn't bud like the 1, I had to turn them to 14:10 on the lighting ratio to get them to cooperate, but I've seen trichomes appearing since then so I think they are finally back on track. The humidity I would classify as low, the tent itself 24 hours highs and lows were 47% and 34% I believe. Temperature max of 82.4 and low of 71 in the past 24 hours. The tent did have a major issue with over crowding, because the 3 didn't flip on their own and got to my lights before I thought to ask for help. I moved one of them out of the tent and used some cotton string and zip ties to bend the main stems back so they aren't touching the lights themselves which cleared up a bunch of airspace. The leaf falling off issue was appearing before that though, it's been happening once a day probably for about a week. It was just noticeably worse having to move one of those plants, everything seems to grow together. I took a picture of 3 of the leaves that fell off I'll edit the first post. Thanks for the help too man.

Hmmm.... those leaves look healthy enough. I don't think it's a deficiency.

Sometimes a plants stems and petioles can grow a bit like celery. I'm not sure if it because of not having enough air flow or overwatering, perhaps both. When they're like that the stems and petioles snap very easily instead of bend. If they were overcrowded and only the leaves that you touch seem to be affected.....maybe this is what's happening.

I'm not sure how long you've been enjoying this wonderful hobby, but sun leaves kind of snap off real easy with a lot of varieties. Others seem to not want to shed them so easily.

If you look at the way the petiole is attached/connected to a stem, it really only takes the two outside edges on top to tear bad enough and the leave is gonna come down.

I image the larger the leaf, the more water within in the leaf and the longer the petiole..... the less of a tear or snap it will take to accidentally buck the leaf.

Not sure if that's what's up with your situation and please don't be offended if you find this info elementary! I figure I'd just throw it out there just in case.

Your welcome for the "help"!haha I can at least help you bump this thread up in the hopes that someone else might chime in for you.

Its not a problem though.

This is my first grow, I have just tried to research before asking questions, so all that is great information for me thanks. It was seriously overcrowded before and that might just have been it, not enough room or light to go around. At this point I am just going to wait them out and get some Stonington blend from Coasts of Maine to give some other seeds a shot as well. Everything this run is a learning experience, if I get enough to stoned too that's just gravy.

I've been at it for like 30 yrs and still learn new stuff each grow. Too bad I'm kind of lazy these days and forgetful on top of that! Mainly lazy.haha

You have the right attitude though.

One bit of advice I like to give new growers is less is more! Except for time spent with your plants and research.

Update the thread if anything changes or no one else posts. You got me curious how it goes!lol
