What’s going on? (Pics)

Hi all,

I’m a N00b and am on my first grow.

Plant has been looking good, but have gone out today and come back to it looking, well, judge for yourself!

It was full and branching outwards when I went out, I’ve come back and it seems to be almost closing?

Any idea? Water I’ve been feeding is ph 5.8, and it’s only had water, around 60ml per day. Growing in tropic vat mix with guano.

On a 20/4 light schedule, using 250w sinmaster light. Temp and humidity are good. Temp sometimes gets to around 31 but usually around 27 with humidity around 55-60%.

Any idea why she’s closing up? Broke ground on 7th July.

Thanks for your help guys!

Tropic BAT mix*

I have never seen that?! I've been doing this about 13 years all together and I've seen branches reach up for the light, but I've never seen a whole plant closed up like that?!

Can you tell more about the mix ur using, is it Coco, is it soil, any other information would help how close is your light, pH, excetera also what was the last thing you did that was different before it closed up like that

Looks like it is charged up on Nitrogen and reaching for the light ...praying

Yeah I mean I've seen the tops of plants do that but holy shit! ..that's a new one on me! (I suspect he's in some pretty hot soil)

P.s. to op, if it is soil you want to pH to 6.5, 5.8 is hydro range

Thanks for the reply guys!

I mean, not very reassuring that you’ve done it 13 years and never seen it! Lol.

Regarding the ph, thanks, I lowered it to 5.8-6 ish because I thought it was best, but thanks for the pointer, 6.5 from now on! (if that is correct for peat/coco mix?)

I’ve posted a pic of the ingredients of my medium, the light was pretty close
I don’t think it’s reaching, but you guys would know better than me! Though I assumed it would stretch its stem, but keep leaves
Folded outwards for maximum photosynthesis?

The last thing I did was water it at lights on (2pm), found it turned in at 5pm...other than that, nothing has changed. Haven’t given any additional nutrients, temp may have been warmer today, Maybe warmer soil as someone stated earlier?

This pic was her 24 hours ago

I’m guessing severe heat stress. The plant still looks hot in the new pic.

No. Peat/Coco is considered Hydroponic and 5.8 - 6 would be correct

Dude just because I haven't seen it doesn't mean much, but that is freaking weird..!

There has been a heatwave in England, which is typical on my first grow! Lol... but I’ve bought an air con, and keeping temps below 30, and a humidifier keeping humidity at around 50+%... it has seen around 32 max while closed up though, but not frequently. I opened the tent at 2pm, she was fine, I watered her with 40ml of spring water ph 5.8 and came back a few hours later to find her closing up as you’ve seen in the pics! If you guys are stumped I’ve got no chance loll

Turned like that in 3 hours if I'm reading you correct, from 2 to 5 p.m.! holy shit

Hold on let me get my conversion scale-out..

I hit those temps all the time in the summer but I have unbelievable air movement, do you have a fan, how close is your light, I would back it off immediately regardless

Btw Don't panic, Ive a feeling next lights on it may be back to normal ?

This is a learning moment for me, I'm sorry it's at your expense but I don't think it's very serious

I should add I'm not a Coco grower, in fact I despise coco, but I have 3x more years of Hydro experience then soil Growing Experience. Normally I don't get involved in hydro and particularly Coco growing issues but I mean this is so weird I'm going to have to follow this

You know who's a good cocoa grower there's a bunch but @Tim1987 comes to mind let's see if we can get him to take a look at this

Literally 3 hours! Detecting a hint of sarcasm there but I’m unsure loll

I’ve got a fan oscillating on it also if that makes a difference?

I like to be under 25 Celsius (77 Fahrenheit)

Is there a fan blowing between the lamp and plant?. If the air is hot and still that would cause a young plant to twist up. It’s trying to transpire more than it can drink.

Try to angle the fan to blow the heat of the lamp up and away some. And to not blow directly on the plant. Just above so the leaves gently shake a bit. But not the whole steam leaning.

Wind also will do strange things to a young plant.

I have an extractor fan, and a small pc intake fan, that run while tent is closed at night (as currently too hot in the day to close!) and during the day it has an oscillating home office sized fan blowing past it, temps never exceed 28 while open, and a humidifier putting some steam through the intake fan keeping humidity around 50%. I’ve moved the light a couple inches further away just to be safe, hopefully she opens back up!

Roger that, I’ll adjust the fan position as it has been shaking, leaning the plant as it oscillates

Not sarcasm, surprise! believe me I've never seen this?

Still don't think it's very serious I think it will be fine next time the lights come on

* sarcasm intended on the damn conversion scale tho, Celsius is like another language here in the states!

Also as Michigan Med said, try to get the fan between the top of the plant and the light to move the heat away as much as possible rather than blowing directly on the plant

Clip fan is perfect for this purpose

Good rule of thumb whenever anything weird like this pops up lower the heat and raise the light is First Response, next response is flush if I've recently added something and pretty much thats all the rules I have

I'm not telling you to flush because you said you didn't add anything but your regular water, I'm just saying that's how I react to weird things that pop up every now and then

Ok so since yesterday, plant started to perk up, then closed again by the time I reopened the tent. as you can see, first pic was 6 hours ago, and it now has opened up again.

I noticed the humidity was low, the humidifier was missing the intake and the tent had low humidity, along with the hot weather and air con struggling to keep the room cool, I’m thinking it may have been really hot and dry?

I have flushed it, and checked the ph from the run off which was at around 6.2.

Also, 3rd pic, this has been a symptom since the seedling had yellowing Leaf edges, and the closest thing I can see is boron deficiency, which would correlate with the low humidity... (humidifier was a recent purchase due to low humidity). I guess the low humidity and high temperatures have caused this?
