promix BX with 25% added chunky perilite
grown in mini hempys from clone to veg @ 4to 1 perilite /vermiculite then transplanted to promix 1 week ago
added maxi & calmag to RO then PH'ed to 6.0 & bubbled for 4 hrs to mix well ppm was 980 (not sure of the conversion cuz its a cheap chinese ppm meter )

I have 5 OG kush plants that were transplanted 1 week ago into 2 gallon plastic grow bags . they are monster cropped clones (taken 2 weeks into flowering ) that while in mini hempys grew great for me .after 4 or 5 days in the new mix they slowed down & the new growth is deformed & the leaves are cupping in . I watered them when first transplanted the waited till yesterday to water again cuz soil seemed dry & the bag was lighter . i noticed the leaves about 3 days ago but figured a feeding would help . these plants look healthy even after the probs they went through with my bad water but they have slowed down , look waxy & the new growth is curling up or cupping .
they are in my veg cab under a 150 watt HPS & 4 27 watt CFL's on a 24 hr light cycle .
they have a fan blowing on them 24 hrs also . i have a 110 cfm fan drawing from the cab through double layered carbon filter sheets with 2 4" x8" passive vents covered with furnace filter to keep the crap out of the cab .
the plants are 15" away from the lights & temps are from 78degrees during the day to 69 or 70 at night .
they have only been fed/watered twice sense transplant once right after & once yesterday .... not drowned just watered till moist ... no runoff at all .

any clues here ? ..... was reading that cupping & waxy leaves are from environmental issues but everything else in the cab is doing great . this is only happening to the OG kush & only sense transplanting . they're big enough ... 8" high or so that i don't think the promix is a prob .... no real nutes in it . but i'm lost here right now tryin to figure this out .
will get some pics up after the camera charges up but figured i'd post this till then .
thanx guys .... i hope its nothing major after the probs i just went through with my water .

oh yeah ..... been checking for bugs constantly cuz of having aphids on my first run & spider mites on my last run .... but no signs of any creepy crawlys so far .

Ok guys heres some decent pics of the problem . the leaves are deformed & cupping ... they look real waxy .

a full shot of the cab so you can see how big the girls are & how far from the lights they are

 

[dansbuds]

according to this chart my ph should be 6.5 or i'm not getting the cal mg & p . or is promix NOT considered soil ???

 

[squarepush3r]

heat or over/underwatering

 

[dansbuds]

bump .....

 

[Buffoonman]

I'm having the same probs with my OG Kush the leaves are curling upwards as though its heat stress or wind burn whilst none of the other strains are doing it. Its a mystery as I'm using the same set up and never had this problem before.

 

[dansbuds]

I'm curious about the PH issue between hempys & promix . if promix is fed like soil then my ph of 6.0 is causing my probs cuz its not getting the cal. mag & P that they need .

 

[Scrogerman]

That margin cupping & leaf twisting looks like heat stress issues to me bro! possibly water stess too, as your high temp is is only 78 id say more likely that. Looks like you have defciency, your looking at a soiless ph if im not mistaken, lower PH than soil!!! The Promix & the Maxi will come with a recommended PH. Promix BX is Peat based so its gonna be a lower PH as far as i know! 6.5 is too high for you id of said, but i dont use promix myself tbh!

EC of that mix is 1.3 -2.0, bit of a difference there isnt there.

Aim your fans at ya light instead of directly on them maybe, scratching my head a little from the info youve given.

What are your Run-off numbers, PH & EC, in & out? Why are you not irrigating to run-off?? Unless you have it dialled-in your not going to be able to see whats happening with no run-off bro! Check the run-off bro & water/irrigate well.

G'Luck with it mate!

 

[compost]

I haven't done micro before but those leaves all look like reveged leaves. I could be wrong but do most of the leaf sets only have one blade on them?

 

[bigwity]

surely that looks like a ph problem if its only in one plant buff i mwould guess it likes a diff ec and ph. my cheese cuts always turn up at the edges in late flower

 

[bigwity]

try a good leech and just plain water for a few days see if it changes if they look waxy n green it sounds like they are full of nutes N makes them go green while P n K make them shine up and thicken, in my experience

 

[DrLongbottom]

Do Not do anything drastic.....there is nothing wrong with your plants. You are getting distorted leaves because you took your cuts from a flowering plant (2 weeks in flower). What you are seeing in the stress the plant received from the revert to veg from flower. Unfortunately for you this is going to lengthen the amount of time that plant must veg before you can flower it out or take more cuts. You should try to get into the practice of taking cuts in veg and this will not happen to you. DLB

 

[bigwity]

sorry i didnt see that they were taken in flower my bad, i cant see the pics. i would wait it out in that case

scrogger ... what do ya mean by water stressed ?
i'll boost the fans to get better airflow ... but don't really think heat is the prob ..... but i've been wrong before !!!
my ph has been @6.0 from the begining .
wasn't watering till runoff cuz i didn't want to overwater them ... have had that prob before .
def's yeah thats why i thought my ph was off but ...... dunno
still have a few bad leaves from the water probs i had a couple weeks ago .... but looking today some top fans are discoloring now too .

I haven't done micro before but those leaves all look like reveged leaves. I could be wrong but do most of the leaf sets only have one blade on them?

these plants were growing fine & healthy till i transplanted them from hempys to promix ... thats when the curling & slow growth appeared .only the new growth has a few spots with 1 leaf .. theres acctually 2 leaves just 1 is really curled .

surely that looks like a ph problem if its only in one plant buff i mwould guess it likes a diff ec and ph. my cheese cuts always turn up at the edges in late flower

but why only after transplanting to promix is my concern ... before that they were growing great .

i'm sorry dude but thats not it .... there is defenatly something wrong here . this plant is not healthy & gets worse every day . i take monster crop clones all the time & they grow great for me .... i'd rather do it this way cuz of all the branching it gives me .

try a good leech and just plain water for a few days see if it changes if they look waxy n green it sounds like they are full of nutes N makes them go green while P n K make them shine up and thicken, in my experience

thanx witty, this is exactly what i'm going to do . gonna leach it with RO ph'ed @ 5.8 for a couple days & basicly gonna flush it till i get enough runoff to see whats coming out of the bottoms of the bags . that should really give me an idea whats happening in the promix .

man this is getting aggrevating ... first i find my water is fucked up & have to switch to RO & everything was recovering nicely till i transplanted these into the promix bags .... its all ways something lately .

thanx guys all your ideas help out one way or another . i'll get this if it kills me .

This is utterly normal revegetation. Don't change anything, it's fine! It will be a couple more weeks before the plant structure really starts improving, though, and I would expect a big hedge to result because it seems to stay stunted in vertical growth while it grows a crown of primordial branches from that stub of a stem. Here was mine:



If you're that concerned about the curling (which seems mostly a cosmetic issue but also like it would lengthen the time it takes to reveg) I would seriously halt feeding completely. It appears to be a sign of overfeeding, specifically Nitrogen. You could also try backing off the light to reduce how much growth the plants are trying to make. Too bad I didn't save middle pictures, but I had plenty of curled growth for a little bit when the plants were adjusting to a rich soil from the standalone rockwool cloning cubes. I think perhaps using clones from smaller branches versus larger branches would make a big difference here.

 

[bigwity]

also make sure your soil isnt clogging in the bottom of the pots,

 

[Stress_test]

I literally hate those forms.

I don't think your problem has anything to do with the clones being cut from a budding mom. I have seen some weird effects but never anything like that.

Anyway leaf edges curling up like that is an indication of heat being a tad high, over watering, or over feeding.

900 ppm is way too high.
Looks like nutrient burn.
I run most plants at about 600 ppm... Heavy feeders get 750 tops, light feeders do just fine on 500 ppm... Speaking of ppm, what brand is your ppm meter? Mine uses a .5 conversion factor but many use a .7 which causes discrepancies.

I went back and looked in the OP for temps and distance from light, but didn't see em mentioned.

I am using the same cloning setup you do. It's really common to see these indicators shortly after transplanting. I would say your Ph is tad bit high, but confirm that from somebody who uses promix. I am thinking it should be a little lower.

Normal reveg is all I see.

OK, if your interested bro!
Water-stress is just one of the many stresses that can affect cannabis, & it has several implications, as i found out last year for the first time.(i have pics somewhere, look exactly like your curled margins)
As far as i know the curling leaf margins(like you have) is one possible sign of it. Im not saying that is that but it is a possible indicator. Over & Under watering plants will cause it, drought conditions can cause it etc, it causes a build up of Abscisic acid or 'ABA'(not good at that time) & will slow growth & affects shoots & growing tips/margins etc. Try a search on it yourself bro, theres quite a bit of info out-there, but most of its complicated as usual.

theres not many things that will cause the leaf margins to curl in that specific way, water-stress is one of them(just an idea), heat another, looking at your plants im seeing a couple of problems.

Were your plants rooted & growing normally before you re-potted them into the promix?
This is a reason why people are mentioning the re-veg(understandably), but the way i took it was your plants were growing normally before you repotted them. Is that right? if it is it aint nothing to do with taking cut 2 week into bloom(before commencement of flowers), ive done it many times with no problems, but it aint ideal & i didnt havent to wait 2-4 weeks for a re-veg either.(rooted normally 7-10 days without fail).

Big Wits sugestions of a leach etc are cool, pretty much the way id go. But i would definately be irrigating to Run-off, just so you can check EC/PH etc & see what the plant requires next. Its gonna be difficult to overwater that promix bx id of thought, its full of perlite(+ you added the Chunky perlite on top 25%).

I wouldnt panick anyway mate, i think they'll come round, but imo you should be checking your run-off EC & PH numbers, do you understand how checking run-off works? read up on that i would. Its the only way to get an idea of plant requirements!

Good Luck mate, i think youll be just fine, stay cool.
