Downward Tacoing on Purple Urkle

Hey I posted this in the csi humboldt thread because I thought maybe this was strain specific, but then I thought maybe it's not. So here I am.

So what's going on is I have these 5 purple urkles and some of them are doing a downward taco. I dont wanna say curling because it looks a little different from eagle clawing, but I might be mistaken. I saw it starting to happen, and thought well maybe it's too much water. So I haven't watered them in three days, but they keep doing it. So maybe not enough water? Maybe it's been the cold, because we have had some unusually cold nights here the last week. Or is it just over fertilization and this is just the typical eagle clawing? Here is a picture:



Can someone please help me out, and set me straight. This is my first time dealing with the purple urkle strain. My other plants are doing fine.


Edit: Info about the grow. They are outdoors in a green house. They are in coco coir with perlite. I usually feed them every other day with one gallon of vegbloom nutirents each. They are on day 18 of flower.

This thread mentioned something interesting.

" A note for the bio folks - as soil dries, the concentration of the remaining salts rises further exacerbating the problem. Leach (flush) your pots once in a while to get rid of excess salts."

I recently started growing in a greenhouse. This is actually my first grow under it. So my plants aren't getting rained on every day like they normally do. So they are actually getting to dry out, but I'm still feeding them like they are getting rained on. So as they dry out, there is an excess of salts? Maybe I should give them just water every other watering instead of always giving them nutrients?

I think it's the start of claw. Sometimes I get that in the corners of my room when they grow higher than the light ie lack of light. If yours are in good light then you should probably back off the nutes a little.

It's been rainy and cloudy the last 4 days, but I think you may be right about backing off. I gave them just water this time around to try and move more salts out of the root zone. Thanks for taking a look and giving me your opinion.

Rules to live by; Don't let your coco dry out...your plants will burn, and don't water with 'plain or empty' water. Always be sure your water has some level of feed in it. Feeding every day is the benefit and advantage of coco, it can and should be done, you simply need to adjust your feed with this strategy in mind. It's nearly impossible to over water in coco...not impossible, but very hard to do, I doubt that's your issue. Can you offer a picture of the entire plant/s? What are you pH'ing your feed to?

They actually uncurled and straightened out after I gave them water. I was expecting them to be permanently damaged like that. Like I said I just started growing under a greenhouse and before that they would get rained on a lot so I think that you may be right on to something as well. My ph is usually around 6.0-6.2. You think I can still feed them every watering until flush? That's been my style of growing since I started using coco. It's really just these new purple urkle plants I'm having issues with.

Will second that. That cupping for me has usually been the very beginning of excess nitrogen and likely a combination of weaker lighting, as when it happened in the past, it was on auto's that got to be too big and thus the edges would get less light and then i get that cupping, but i know too much nitrogen played a role in it as well.

Your girls look pretty nice...and yes, if it were me, I would feed every day...even during the 'flush'...just at a much lower %...say 25 -15%. I never use plain water. I generally pH @ 5.8, but you're close enough never the less...and your plants look good, so I wouldn't change that aspect of your program. Carry on friend, looks like you're going to have a nice go of it.
