Your more likely going to have a nute problem or a lockout rather than a burn, I would check the pH run off I remember helping you before; new plants?
How was the other plants doing? You never gave an update like we all asked for

Also is that tin foil on the side of the grow box?
If so remove it; it absorbs more light and causes heat problems and is crap for reflection.

WHat are the temps like at night time?

same plants

I will get ph-meter this week I hope...

Yes Its Emergency Blanket, Its very thin..
The night temp is around 65F

Ok, now I remember, I told you in your last thread about the same problem you are having.... why did you go make another thread when you are having the same problem, pretty much it seems you did nothing to fix the things I told you that you need to fix.......

Its not heat stress anymore I think...

 

[MynameStitch]

I said something else besides heat stress If I remember correctly........

 

[IlluZiOn]

The damage won't recover and if it is still doing it then you will have to move it up a little bit higher.

?

The new lamp is about 31cm away form the plants, and lamp is not hot, I can hold my hand even on the lamp, because fan is blowing directly and cools it down.

The new lamp is Philips 100w Ceramic metal halide, 8800lumens.

 

[MynameStitch]

Your temps are too cold now, it's not heat stress; you need to bring your temps up; but that is a problem that will cause more problems, your problem right now is you need to get your pH tested as it looks to be more pH related; but temps don't help either.

Stitch, I believe he noted that his Canopy temps were 25c/77f so I would advise him not to raise the temperature at all unless his ambient and or root zone temperatures are falling way below that. I believe he needs to check run-off ph and see what the ppm of it is as well, maybe theres not that much food in the soil.

 

[DIGITALHIPPY]

its ph related and if u cut the problem off its harder to see...
so dont freaking cut the ends off

Canopy temps and room temps are a wholenother story...... not to mention he just noted a few posts ago that his night temps are 65F which is the remark I was saying was too low

Not saying his canopy temps were too low.

I know DH! I hate when peeps cut off the damage; it's so hard to tell what the problem is/was :/

 

[ackuric]

Stitch, you didn't say canopy temps nor did you refer to the night time temps, you just told him to raise temperature. Please be specific as to not confuse anyone, especially the OP. I'm sure he already is.

I don't see temperatures like that damaging his plants the way they are (65F at night) which is actually not a bad temperature, a 10 degree drop in daytime to nighttime temperature is within ideal range from every piece of literature I've ever had the opportunity to research. Maybe I'm wrong but, I have both read and experienced that colder temperatures only seem to slow growth at a range from 40-55 degrees Fahrenheit, and temperatures below that will completely stop growth and induce stress, both of which require recovery. Theres not enough temperature fluctuation in his setup to really consider anything temperature related as the culprit, unless the plants are sitting on a 50F degree concrete floor and the roots are shut down from their temps, which they appear not to be.

Just MHO, although the less fluctuation from day to night is overall better for plant health, I really do not seeing 65 degree temps at night causing that damage.

I bet his ph is high (7-8) but I can only base the assumption on the fact he uses rain water and never ph's it, and has yet to test his soils ph.

 

[MynameStitch]

It's very obvious and easy to see that right after he posted about his temps I made a comment about them........

I have seen soooooooo many problems with these temps when they are this size, it won't affect older plants as badly, but as for young plants and older plants, nutrients are absorbed at certain pH levels and nutrients are not absorbed properly at cooler temps, phosphorus is the first to be locked out and normally it's under 70F to 65F range.

It also depends on how much stored nutes the plant has to use it when the cooler temps arise.......
Why do you think cannabis shows the pretty colors when the temps get cooler? Most of the time strains need these cooler temps to show there colors and the colors you see if nutrient problems.

Nitrogen gets poorly absorbed when you overwater, soggy soil inhibits it's absorption rate by the plants.

I could go on and on, but those are some good examples......

If you don't believe me I can point you to a few members who can confirm about these temp problems easily.

I have both read and experienced that colder temperatures only seem to slow growth at a range from 40-55 degrees Fahrenheit,

Where did you read this from? I would like to see this and is it about cannabis or other plants?

I never said temprature was causing his problem, all I said was to bring his temps up; I always look for other problems that may arise if it is not fixed; I said his problem is pH related.

Where did I say his problem was temperature related? Not once did I say this I said in post #8 that his problem is what I said below..... I said temps don't help but I also clearly stated it was pH related.

Your temps are too cold now, it's not heat stress; you need to bring your temps up; but that is a problem that will cause more problems, your problem right now is you need to get your pH tested as it looks to be more pH related; but temps don't help either.

Like I said, when I post I check for all problems that can be causing it and future problems that if not fixed will happen, not just what the thread starter is looking for, I go beyond that.


Digital happy had no problem reading my posts..... as for anyone else rarly have a problem decipering my postings.... why are you getting so confused?

its ph related and if u cut the problem off its harder to see...
so dont freaking cut the ends off

Stitch, I read what i stated about temps in Marijuana horticultural books, try to just google it, every resource you seek will state what I had about temperature slowing growth at those ranges, and stopping it below them, and yes it refers to cannabis. Reputable resources that is. Did you know that low temps even slow h2o? Hence the joy of beautiful ice cycles in the winter. Of course lower temps slow things down, even your itty bitty fingers.

I live in Colorado with an EXTREMELY cold climate, I have never witnessed such profound problems that the OP's plants have exhibited in my life just from ambient night time temperature which I have personally had drop to 40-50 degrees on a constant basis, with both sativa and indica varieties, indoors and out, while retaining the most beautiful and lush growth you could imagine for the conditions. Plants can adapt, hes not freezing them. If his soil is overly damp, and cold, thats another story. No reason to even mention that to ME and say you can go on and on, i know about that, mention it to him. I appreciate all of your input and advice, and when you disprove my statements about temperatures, more-so with evidence, since I have seen cannabis plants live in colder conditions i'll swallow my tongue. If temperatures are affecting anything it is his root-zone, and therefore he should get a seedling heating mat or something of that nature, rather then trying to fight his entire setups temperature with much more costly equipment/means.

 

[MynameStitch]

You are going completely overboard now; like I said I am not saying his problem is caused by his damn temprature all I said was is that his temps are low; from my experience and from what I have seen I am going to go by what I have seen and my experience before I go by any book and that is the way I have been since I have been growing.

And not to matter; all strains are different too some can handle warmer temps and cooler temps without a problem.

if your plants are having problems and temps are low it may be a facter.

Read icky420's thread; won't be hard to find in the infirmary; check that thread and read it all then come back to me and talk about cold temps and if they can cause problems or not; he had his room temps cool and was showing phosphorus purpling lockout issues and I told him to rasie his temps and problem went away and they grew very quickly.

Problem is,speedy growth can mean different things to anyone, what may be fast to you is not fast to others

Where are these pictures of these lush green plants in these temps at? You have no gallery.......

 

[ackuric]

I'm not going to send you pictures of 6ft + plants outdoors or their stages of development as they are none of your business. you are asinine and using vulgarities which i find extremely inappropriate, grow up and act civil.

From Jorge Cerventes Book, since you are unable to do your OWN research.

Temperature both low and high temperatures slow the growth of plants. Largeu fluctuations in temperature more then 15 to 20 F causes SLOW GROWTH and SLOWS THE PLANTS PROCESS. IDEAL RANGE WITHOUT USE OF CO2 = 65 NIGHTTIME 75 DAYTIME.

His temps aren't too low. He would be wasting resources raising them.

 

[ackuric]

upon stitches request, check my gallery, the date on the photo is accurate and the plant was grown in Colorado's COOOOLD climate. Of course I had to chop her before the first BIG freeze (she withstood a few mild freezes with no hint of stress, just slowed growth for a day)

Find someone else to try to use to boast your ego thats apparently drained outside of these forums. Forum bullying isn't permitted or really excusable by any means unless its you doing it from what I see, and I've only tried to be nice to you in every sense of the word.

 

[MynameStitch]

First off; where did I say something quote un quote

they are none of your business. you are asinine and using vulgarities which i find extremely inappropriate, grow up and act civil.

Everyone around here ask's for pictures when people give out advice; sorry if I offended you; you are not the only one who I have asked and I am not the only one to ask something like this........


Another thing; I did not know trees keep there leaves in 40-50 F weather with so lush and green!; must be a freak of nature!

For an outdoor plant that is small; I grew bigger plants indoors.

I asked for pics with plants taking this cold weather........ you have yet to prove this. Not to mention your plant is WAYYYYY bigger than the dudes plant this this thread; small plants can't handle these temps compared to plants you are showing in your pic, let alone it was taken in the midest of who knows when, let alone it still looks pretty damn warm out in those pics!


I have no ego dude; I spend my time on here day after day and I am not even currently growing; I am here to help; not to boast my ego.

WTF I am in a conversation with you how the fuck am I bullying you!???
I am being nice and why don't you write in this thread what you wrote in my pm for all to see rather than sit here and keep arguing about stuff?

You are pissed cause I asked to see proof of your grows? where the fuck is that going with bullying you!? If anyone needs to grow up it's you; you act very snobbish dude getting offended because I asked to see your grow pics wtf; that is one of the first things asked around here when a new person comes here giving advice; so you grow the fuck up dude.



I showed proof to you by telling you where to find it.

65 is the cut off and his temps are in the cut off range I Have seen issues with temps in a little under 70F
So I know problems can occur and I am not going by his book cause I have seen it and diagnosed it and had updates so I am going by my experiece before I go by a book anymore. This is not saying You can't teach me something new, I am not closed minded by far; but all I am trying to say is I know for a fact temps under 70F can cause slow growth and cause purpling and color changing which causes slow growth and problems.

Update

 

[MynameStitch]

Have you done anything that I told you that you need to do?
Your plants will continue to do this until you correct the pH issue......

How close do oyu have your lighting too btw?

REmember what I told you about the tin foil? It traps in heat? But it also can cause hot spots, remove the foil dude.
