pig-tail leaf curl

[MynameStitch]

yes blackmelo i agree as well

what i have come down to is this

he is using more peat than anything else...... but the other problem is he is using soil mixture too

so hes like growing with both soil and soiless and that is where the problem lies, hes in between the lines here and the ph he gets wont be good because hes growing with both soil and soiless has 2 different ph's

i think his plant wont ever get better unless he uses either soil or soiless one or the other

for the leaf curl is what im talking about

 

[sproutco]

your planmt has to much nitrogen and its locking out iron...thats the only explination for this then the curled leaves are one of the distinct cararistics of to much ntirogen

Nitrogen does not lock out iron. New growth would be yellow with iron deficiency. What you would see first is a lack of copper. I stated that pig tailed leaves are a sign of copper deficiency. Leaf ends going round and round. So mynamestitch, you may still be right about too much nitrogen and a claw like look to the leaves too. Sometimes excess phosphorus also causes copper deficiency. With copper deficiency, I would also expect wilting without chlorosis (yellowing leaves) but it is not doing that.

 

[MynameStitch]

sorry i should of stated my sentense better, ya i know nitrogen doesnt lock out iron..... my wordding was poorly i see where you get why you said that lol

did you see copper defieicney in cannabis or other plants?

i know copper does show yellowing leaves like that but its mainly on older growths

and it has a blue hue to it.....


for a fact i know its either water stress, over ntirofication

and i know its caused by his ph because of the soil mixture he is using, part soiless and part soil....... thats like mixing hydro and soil together and ive seen it done and they have problems lol

he is locking out some micronutrient which one it is?

it could be iron, copper one of those 2...... and the reason why your not seeing the full out blown copper if thats the problem is because its not caused by to low of the nutrient its caused by lockout......

after flushing this morning i turned the plant around and took some pictures . maybe these will provide some missing clues ? these are older leaves down low on the plant.

 

[sproutco]

should i get some other ph strips somewhere ?

Yes. You might try a pet store that has fish tank supplies. You might try getting ph test strips in the range 4 to 7 or something like that.

 

[green_grow]

o.k., wide-range ph testing kit from petcetera reads run-off ph of 7.0 . looked in on the plant just before lights-out and leaf-curl is, if anything, slightly more pronounced .

 

[MynameStitch]

the leav pig tail curl is caused by a few different things
this is why i havnt sen this before

your problem is this, your soil mixture, your using more peatmoss but added soil to yoiur mixture, therefore your ph for the plant cant be where it needs to be

if this is the irst time you used this mixture i would make it the last, either go soiless or soil

you need to buy a soiless mixture you cant make your own unless you know how to like adding most peatmoss and other stuff soilless mixtures come with


your plant is confused, and i consulted with a good friend who knows alot about cannabis, and he said i was correct, your plant did show moisture stress, the leaf curl under is sign of moisture stress

and considering that you added more to your problems
my advice is this
get it outo f that soil mixture for the time being i would keep your soil ph at 6.3 in between to at least somewhat try to be in the middle of soiless and soil ph

 

[green_grow]

thanks, stitch . i was actually considering pulling it out of that mixture and going back to the mixture that it vegged so well in (topsoil, perlite and soil booster). i wanted to hear from a veteran first though .
for the record, this mixture (peat moss & soil) was something that i concocted on the spot. dont ask why, just a rookie mistake. my question now is ... the plant is good and soaked from yesterdays flushing; should i let it dry out and rest a bit before transplanting ? i am thinking it may have been a bit stressed yesterday because in order to flush i had to take it out of the cabinet and into the bathroom for a while. whattya think ?
p.s. how do i get my ph down to 6.3 ?

 

[MynameStitch]

anything like that will stress the plant, but i would wait untill your plant dries out a bit to get it out of that mixture, once you replace it, add some dolomite lime into the mixture,

1 cup per cu feet of soil

 

[green_grow]

sounds good. will report back in when any changes happen .
thanks a bunch for the help.

 

[sproutco]

the ph strips i bought only measure as low as 6.2 . my reading was below that

Now your saying the ph tests 7. Make sure you are doing the ph test right. Here is a link: http://www.icmag.com/ic/showthread.php?t=32760&page=1

 

[green_grow]

yes, sprout ... the ph when tested with strips was below 6.2. when i used the wide range ph kit (using droplets in a test tube) it came out at 7.0 (maybe SLIGHTLY lower, judging by the colour). i followed the pour-through method , giving it a feeding/watering first. the only difference was on the 2nd test i didn't include any feed, just poured enough water in to produce some run-off .

 

[green_grow]

new problem ... plant has gone hermie on me . took a couple of close-ups but they are not good enough to bother putting up here. don't think there is any question though, even as a rookie i can recognize a tender young seed.

wondering ... are hermies smokeable ? i still have a fairly low tolerance so if hermies have a modest amount of thc maybe i should carry on and take this plant to the finish. the experience would be good for me , i think . are hermie seeds any good for future grows ?

 

[MynameStitch]

yes they are you wil just have to pick out the seeds if the pollen sacks burst, they can hermie half way late and not burst open bu have late nanners inmature pollen sacks

hermie either from genes or stress from this problem you have with ph issues
i wouldnt use the hermie seeds unless you can grow them without stress like the growing conditions are with your plants now

even then its not 100% sure they will not hermie, even femizned seeds hermie if they are not growing in 100% prime conditions

 

[green_grow]

hang on a sec ... i think i am confused . my plant is developing SEEDS, not pollen sacs. does that make it a hermie or does that make it a pollinated female ? (i had a male plant in another room earlier, and i thought i killed it early enough but, i guess not ? sorry to confuse things . if it is a pollinated female does that still make it smokeable ? are the seeds hermie seeds or 'regular' seeds ?

 

[MynameStitch]

there has to be pollen sacks in order to make seeds, yes it is hermie

plinated females are smokeable, you just have to get rid of the seeds if there is any in the bud

are you only using cfl's on the plant that has ph issues? the plant that is the first pic you posted in this thread?

 

[green_grow]

stitch; i am using a 150hps plus the 2 x 27w cfls . i have only one plant. the male was killed earlier. all pics are of the same plant. the cola pic above was taken a week or 2 ago. the pic of the seed in my palm was taken today.

 

[MynameStitch]

how close is the 150 and the cfls to the plant?

see some of the curling may be caused by heat issues too
that compact fluro is very close

compact fluros can and indeed do cause heat issues to the leaves and can be one of the causes of curling

but you have multiple problems herem, im just letting you know for future reference
