Hello new to all this forum business so forgive me if I mess up

[LeeH87]

My plants are just starting week 5 of flower just gave them there first pk but I noticed a few days ago the leafs starting to curl can any one give me some advice please

 

[StoneOtter]

Welcome Lee, nice work to get them this far. How about a pic? How are you growing?

 

[Enr0n]

Yes pics and your set up, grow medium, nutes etc.. would help

 

[LeeH87]

I'm growing them in canna coco using canna a+b plus canna boost 40ml of each per 12 litre bucket hand feeding them. I just introduced canna pk to it aswell. I'm trying to up load a pic now but can for some reason it won't give me the option to when I try click on attack files

 

[013]

How often do you feed them? Probably just user error on the pics try the upload instead of attach

 

[LeeH87]

I feed them every night some times 2liters some times 3 depends how light the pots are. My temps are abit low I've got 3 600w lights in there and 3 radiators it's a loft grow and insulated but csnt keep the temps up it's about 20-22 lights on and 12-14 lights off could this be a factor. How do you upload a pic it tells me to drop image but don't know how

 

[Pat Puffer]

Find the "attach files" button. Click it...

Select your image. Click "done"

Wait for them to up load... Click "insert"...

voila...

 

[LeeH87]

Nothing happens when I click on it god knows what's up with it

 

[Pat Puffer]

Back out the site and log back in. So sorry for the inconvenience. It may work...i am clueless.

 

[LeeH87]

I took theese last night

 

[Pat Puffer]

Wow. Nice set up. Leaves curling, aye? I see it. You say your temps are on the colder side, though. My 1st thought was going to be heat or light stress. Most of the curling is happening on the upper leaves, correct?

 

[LeeH87]

Thanks mate Yes it's on the top leafs do you think my lights are to close to them

 

[Pat Puffer]

Taken from another site...

"...When the serrated edges of marijuana leaves curls or tipped up like that, it’s often a sign of temperature stress, overwatering/root problems or extreme humidity levels."

Extreme humidity is either too low or too high.

Watering habits are important but since you made it this far I think your watering may be okay.

What week of flower are they again? Have they stretched in to the "too hot zone" of your light(s)?

Hmmm...to compensate for the heat...

Have you tested the temps at the canopy or just the overall room temps. The overall could be cold but right under them lamps is probably hot enough to curl some stuff.

 

[LeeH87]

OK my thermometer is near the floor in my room so tonight I'll put it at the canopy area and test that. They stsrted the 5th week of flower yesterday. I'll check canopy temp tonight and grt back to you thanks for the info mate

 

[LeeH87]

Hey guys been busy the past couple of days that's why only just replying I checked my canopy temp and it was 39 degrees!! I've raised my lights as hight as I can get them now and moved my thermometer to middle of the room hanging jsut above my plants and got a temp of 27 I also turned my extractor up so it's sucking more air out.ill get some more pics up tomorrow and show you the leaves seem to be going back to normal. thanks for the info

Evidently your grow warmed a nearby wasp nest. At least you didn't get stung.
