Curling twisting leaves at same level

2nd week flowering, all is good...plants are manifolded so all nodes are pretty equal....lights kicked on today and for some reason, most of the leaves 3/4 up from the bottom are curled and twisting, going crazy...leaves above and below this level are fine. Temp dropped to 60 last night, 71 with lights on....and it's the plant closest to the fan..but I don't know why it would only be the same node on each top??? Same plant had done this before with bottom row of leaves and was fine after I cut them all off. Three plants total, Same strain, only one has the problem. The budlets look fine though.

Have you tried moving the plants around so others sit close to the fan and you can see if it happens to them instead?

Oscillating fan I hope and not a direct blast of air hitting that one plant maybe? Plants get wind burnt too.

What kind of lights/reflector you using? Looks a lot like leaves getting slowly cooked in a hot spot.

Not any kind of deficiency so it's got to be an environmental problem of some kind.

I found a great spot to download FREE POT BOOKS . I downloaded a grow bible first and getting some more. Book looks great and complete like the real one I have here. No web site but just a page of links. Just right click on what you want and then "Save Link As" to download so they don't open first as many are 50+ megs. They got lots.

:peace:

400w HPS open hood, 76 degree avg temp at top of canopy (62 at night) 38% avg humidity, oscillating fan, leaves lightly dancing, Fox farm ocean forest soil, Fox Farm Tiger Bloom nutes every other watering. 7.5 Gal pots, 1.5-2 Gal water @ PH around 6.2-6.3 every watering. 3 plants total...same strain, all manifolded the same, same water/feeding schedule, 2 growing more lush than this one, all tops exact height, and 10-14 inches from bulb. This one has been a little less bushy for most of their lives, and the curling has happened once before....it was all the fan leaves on the bottom nodes (Since manifolded to 8 symmetrical tops, it was 16 fan leaves in total at the 3rd node each.) I plucked them and it was all good until I went In yesterday and found that all fan leaves at the same node of each branch (like before!) had curled twisted and started drying up. I figured if it was environmental I would see some curling on the other plants....or maybe on some different modes not just the same level. Very strange!!!! I am going to draw a rough pic to show what I am talking about. It feels like some kind of strange mutation rather than anything else.....?

Example drawing....sorry about the terrible handwriting and drawing skill...but you see what I mean, the plant is all symmetrical so I can pin point exactly which row of nodes is curling.

I've been scouring my grow bibles and looking online and can't find anything that fits your situation. When things go south on plants it's usually a class of leaves. Grow tips when micronutes are screwed up, older fan leaves when macronutes are screwed up and middle fan leaves all over for all sorts of reasons but not just the middle of the plants.

Might have to lollipop them and hope it doesn't move up the plants.

im guessing

you've over fertilized

you didn't mention how much fertilizer per gallon your mixing or what EC/ppm your mixing it

Your whole garden has heat/moisture stress.

Even your good leaves are curling down.

Phosphorus problem? Toxicity or deficiency? I've only fertilized once...about 4 days before this. I'm not sure much about nutes...this is my first time even giving them a try. Wanted to get soil down good before trying to boost growth. But on the bottle it said 2-3tsp per gal for general feeding. So I did about 1.8 tsp (measured with an oral syringe for accuracy) and gave that plant a gal and a half. NPK ratio 2-8-4. As far as heat stress, I had a little trouble with that a couple weeks ago. But since I started flower it hasn't gone over 79 degrees F, and 55% humidity. The lights kick on in about 15 minutes so I will be able to see if anymore twisting/curling happened over night. Could it be too cold at night??? 60-61 degrees. And it's definitely not the "whole garden" it's only one of 3 plants doing this. The other two are growing perfect. I'm fact I was going to do some light defolliation tonight on them and clear up some excess shade. Aside from the one plant having the leaf twisting....the lower budlets are about double the size of the other plants in the same location, I'm sure because of the extra light penetration from the leaves fucking shriveling...which is cool I guess...but I would rather find and fix the problem, and do the defoliation myself. The next watering is nute free...so hopefully if it is a P toxicity then it will help clear that up. Thanks for all the help everyone. I'll post more pics in the next hour when the girls are awake.

Hey, so it's been a few weeks now. Repotted In 7.5 Gal standard black pots, Fox Farm Ocean Forest as before...started feeding FF Tiger Bloom fertilizer, alternating every other watering with Molasses (figured It could use the extra sugar since I pulled all it's leaves!!)...it's end of 6th week 12/12. Two days ago there were a couple bananas on two of the tops, I plucked them...not sure what else to do, it was my first time having them pop up and I just wanted them gone!!!! Everything seems fine except what few leaves are left...they are starting to die off a little early....but it's all the plant has!! they are maybe 2 weeks from harvest so I will post some final results for everyone...this has been pretty gnarly haha. I actually have one more question I am kind of stuck on if anyone still here has any feedback... should i start flushing like normal with the other plants that are fine? Or continue feeding it a little longer to make sure the buds ripen all the way and do a shorter flush? (I am doing two weeks for the others.) Or just keep going and see what happens....
