Temp. is currently about 28ºC. PH I can't really check it - haven't checked it a single time since start, so what would suddenly change that? I might be asking a lot of stupid questions, but I gotta learn somehow

no problem, there are only stupid answers
lets start with the Heat as I don't think it is a problem, 28C should be ok, tho optimal is between 24C and 27C I just see small signs myself as Im hitting 30C
and it also look different, heat more make the edges of the leaves curl up
that more look like a PH issue, I have seen on my own plant`s, both when I add to much lime to my soil mix and it become to alkaline or when I grew in pure coco and did`t PH my water probably (5,6 - 6,2 in coco like in hydro)
I also seen it from pictures in here where people had problems at the end of a grow as there soil became to acid for the liking of MJ (nutrients build up in the soil, do a flush)
a PH that is off to much will make the leave`s curl up and down and also make the leaves cup upwards
a to alkaline soil is hard to correct, other then keep watering it with water with a lower PH
a to acid soil is easy to correct with some garden/Dolomite Lime or Mearl (oceanic lime)
but only way to find out what your soil`s PH are, is to test it with a soil probe or one of them cheap drop test kits (har dem i silvan)

Seems like I gotta figure out a way to flush and test the runoff.
Roughly 3 weeks till harvest, so I really hope they bounce back from this (whatever the cause might be).
Seems like I'm off to Silvan tomorrow!

What makes you say that?

yea some more then others are really effected if the PH slight off to much
I would get that cheap soil test kit in Silvan
http://eshop.silvan.dk/webapp/wcs/stores/servlet/vare/ecostyle-ph-tester
and see for myself, if its too low (under 6 in PH) I would then get some Dolomite lime and do a top dressing ( a few table spoons on top of your soil before you water)
that will take care of the problem until harvest come, IF we talk about a to low soil PH

btw
do you use normal Tap water ? as I believe our tap water hold more then enough Lime and is coming out about 7-8 ( 7,4 according to my local water plant`s)
check your local online

and I hope for your sake your not near that tractor that did tip over the other day spilling 4000 L roundup near a local water plant in the north of Sjæland

ooh yea, and about run off, don't rely to much on it, to many varies, just pass through your soil, what was the water PH to start with, how much nutrients/salt`s build up do you have, what is the PH of your soil to start with, IMO the only thing you really can use Run off to is to keep a eye on it and see if it go up/down and then do a prober soil test, a soil probe will tell you more accurate, if it is a quality one, the cheap test kit beat most cheap soil probes and is accurate enough to tell you if you have a problem on your hand and in what direction

Yes I use tap water. But it's a few days since I last watered them, so there should be no relation.
I just tested the tap water with my Hanna ph meter, and it reads 8.4. A bit high, but still within the normal limits of tap water.

yea but not the limits of MJ, sure the soil will be a buffer here, but 8,4 is still a bit too high IMO, in soil it should read between 6 and 7 with 6,5 as optimal
I use a bottle of GH`s PH down like 100kr for a bottle and last me a year soon and still 1/3 full I also had one of them small test kits like the one for soil but made for water also about 100kr and go a long way, but I now know my tap is coming out around 7,5 so if I use 0,5 ml PH down in a 2L soda bottle I end up around 6-6,5 witch I like as it seem`s like the alkaline tap water make it crawl up agin over a day
agin soil do work as a buffer, but will have a hard time with +8PH water
also when you buy soil in the future, make sure you try to find them with a PH between 5,8 and 6,5 as some cheap supermarket soil`s keep to much peetmoss and is to acid with a pH between 5,2 and 6

but first of all find out what your soil PH is, then act on it
a quality soil with a PH with in ranges and a very light and airy structure is a cheap and very good move if you want to keep healthy MJ plant`s
same is some PH down if you use tap water and its coming out at 8,5 tho if you Etc. use floranova every watering like 8 ml Im sure you will be close to optimal as it will make it go down a bit I know when I use the Lucas formula with 8ml micro and 16ml bloom in a gallon of water (4L) I get close to a PH on 6,5 with my 7,5PH tap water

Yea I know about the lock-out - been look quite a lot into it for when I start hydroponic after this grow.
I just tested my water with fertilizer and it reads a ph of 7.4. This is the same fertilizer enriched water I've been using since I started this grow - so that could very well be the issue
I have some Hy-Pro -Ph, I guess it would be a good idea to use that to dump the ph a bit.

yea get it down a bit, aim for 6,5
and you better be ready to be much more precise when you start on hydro or you will fail
a quality PH pen (dunno if that is what you have ?) and a Ec meter is a must IMO like a lot of research, soil is forgiven, hydro is`t
and I dunno about our tap water with hydro, some thing that have keepet me from looking more in to hydro, think I would invest in a RO filter if I would move in that direction
and a good nutrients with all the micro and trace elements is also a must as you don't have it in the medium, all the plant require you will have to deliver
tho once it works its amazing to see the results, I just don't like to keep a water tank on the second floor with neighbors under me and alkaline tap water with no RO filter and no PH/EC pens aso don't work either, so I will stick to soil and work with that, tho coco and hempy or maybe a small DWG pot is also options, maybe in the future, but it will require some investments

I have ph and ec meter for when I start hydro. I have calibration fluids for both as well. I got a complete set of Hy-Pro nutrients for hydroponics.
I think I'm ready for it.. time will tell!

No change. They still fold.
I haven't done anything to the soil since the start. Problem is that the place they are now, is a bit cramped and they are quite a bit unsteady (due to lack of a fan) - so flushing will be hard to do. But if that's the only solution, then I will have to figure out how to do it.
