Some oddities with leaves

[Alliaana]

I'm a complete newbie to all this. A lot of improvisation went into the first two plants (including building the growbox from scratch between weeks 2 and 3). All things considered, as far as I can tell they've been doing pretty fine.
I know my lights are not ideal (better ones on the top of my to-do list), but should be sufficient. One of the plants (autos) looks normal to me...as normal as it always has.
The other one has always been ahead. Sprouted 3 days earlier and went into pre-bloom mega early. Around the end of week 2. Growing tall as opposed to the shorter one's bushier approach.
But now there's some maybe issues on the taller one. I'm having trouble finding anything that matches online. Especially since both the symptoms are very localized. One being "floppy", somewhat malformed top leaves on two of the side branches. And the other being some yellowing on and around one of the blooms.
Does this ask for any interventions?

It looks like it's re-vegging

 

[Johiem]

Temps, humidity, lighting schedule, planting material and feed/ watering schedule please. I would lean more toward a Ph, or lockout issue.

Can that even happen with autos? What could possibly trigger it?

25-27°C, 60-70% humidity. 18/6 the whole time. Got em in soil (biobizz lightmix with some extra perlite added). For watering/feeding...I tend to poke a finger in the soil and when it's just barely moist, I give them water with basic nutrients. Usually that's around two and a half day in between.

Yeah I think you're right. I don't think autos can re-veg. You said only 1 is an auto though right, so I'm assuming your other plants are re-vegging seeming as you have them on a 18/6 light cycle? Those single bladed leaves and are a tell tale sign of a re-vegging plant

Do you feed to run off? You could have a buildup of salts in the media that just need leached and reset. I give my girls a good rinsing about one a month if they are showing stress.

If you've got a photoperiod plant in flower and it's on a 18/6 light cycle then your plant is re-vegging, there's no doubt about it.

Oh, I meant both are autos, sorry if that was not worded properly. They're both the same - Northern Lights auto. Everything they're getting is the same too. Except the light. Got some LEDs lying around that I use for various other plants. So been wondering if they'd be up to the task here. Gonna finish these plants as they are and then start the next batch under the recommended lights to see how much of a difference there is

You mean whether there's water leaking down the bottom after I they get it? Very little. And what does flow out quickly soaks back in. They're in 15 liter fabric pots. Getting around 0.5-0.7 liter per watering now that they're bigger. Should I give more to make the pot leak? Or take them to take bathtub and flush the soil? I admit I've been a tad paranoid about over-watering as that's the fastest way to kill most of the other plants I've grown.

 

[Johiem]

Over watering is one of the easiest ways to kill them yes, but if you're added nutrients don't get flushed out whatever isn't used just sits there and can mess with your Ph. As long as you have good drainage and aeration in the soil, a good flush won't hurt them. I'd run about 20 liters of water Ph'd to about 6(or as close as you can get). I find the bathtub or shower stall most convenient if you don't have a floor drain. She'll probably show she's hungry till her next feeding but should perk up I'd think.

I don't have much experience with soil and autos, but from what I can tell, I would say you are going to be fine and will make it till harvest

Water volume isn't the issue, ~20% runoff with bottled nutes is the norm, but the amount of time you give to let the medium dry, between waterings.

That's just it, the "run off" isn't running off, it's being sucked back in.

Please note these are only guesses and suggestions about what I'd try. Microbes may help also but that could be difficult to advise on depending on where you're located. I use Recharge and love it.

If he's in living soil, no need for runoff, but if he's watering in bottled nutes, ~20% runoff is needed to remove residual salts. Do you water to runoff with recharge?

Yep. My yard gets the run off.
There are microbes out there that can actually eat the salts, Recharge has some(i don't know which ones specifically) and, from what I've heard, Dynomyco was made in one of the saltiest environments on earth just to make it tolerant to nutrient salts.

Well, never flushed any of these particular plants yet, so...sounds like a good time to get that particular first experience ^^
Soil should air and drain just fine. Is a light mix to begin with, added more perlite into it on top of what was already there and it's all sitting on three centimeters or so of keramzit expanded clay.
Gonna check the current pH of the soil when I come back home, too
Mostly I'm confused about how localized the symptoms are. I'd expect them to show up more "globally" As a whole she seems to be doing fairly fine (photo)

Welp, neither do I. Just figuring things out as I go. All things considered, it could have gone much worse

I see. Good to know, thanks ^^
I take it that the runoff flushes out what remained from previous feedings?
By living soil you mean compost and all that stuff, right? Just not familiar with all the terminology in English yet
If that's the case, then no indeed...no living soil. Just a mix I bought and a couple bottles of Atami fertilizers I've had lying around

Yes, runoff flushes out unused nutes.
Yes. Living soil means compost and stuff. Lol

Okies, did the flushing. Turns out my tap water is more alkaline than I thought even after filtering. Took eight big tablespoons of vinegar to get them 20 liters down to pH 6. The soil itself was still slightly acidic tho.
Took some more pictures while I had her out of the box. Some of the top leaves are slightly curled...too hot underneath the lights maybe? Could that also be playing a role in the yellowish spot? Given it's the closest to the lamps.
Seeing the size of various basic tents and boxes, I expected 150 centimeters to be fine for autos. Mistakes were made...but won't be hard to lift the ceiling as there's still space above. 2 meters okay?

 

[Johiem]

Your light height will depend on its strength, I don't think that yellowing spot is from the light. 2 meters, is that your ceiling height? I shoot for 18-20 inches off the top point, not sure what that is in centimeters, 60?ish?
Autos can be deceptive in expectation, everyone says they are smaller plants, and I'll agree to an extent. Indoors I've had 2 autos that have out performed some of my photo girls, so they can get sizeable.
Slightly acidic is what cannabis likes to grow in. Watering / feeding Ph around 6 is about perfect in my opinion.
Can you get a clearer picture of that top cola? You may have a nanner situation starting. Nothing perverse, she just may be trying to seed herself. A nice sharp pic should help determining. Should be able to resume feeding, aim for that same Ph but some variance is OK 5.8 - 6.3 is my preferred range. Were you able to find any sort of microbial product?

My lights are fairly weak and not made for these particularly sun-hungry plants. So Im using multiple and they are very close (never more than 10 centimeters above).
No, my ceiling is a tad over three meters...planning to make good use of that in the foreseeable future ^^
Just the growbox is made by repurposing bottom two thirds of a piece of furniture I made years ago for very different reasons. Lifting the ceiling and adjusting some more would be easy.
20 inches should be like 50 cm me thinks.

Oh, what could cause an auto plant with no access to any guys to attempt for seeds?
Gonna try to get a better pic when I come home. Two hours or so.
Getting anything in the next couple days might be tricky. Doing 12 hour shifts. All them nice stores are closed before I get in and after I get out of work. Could check online and have someone pick it up for me tho...if theres a good chance it would improve things

Okies, got a couple pictures with a better camera. Hope they help
