Hm. Leaf edge curling?

[Koskesh]

My rh remains in the 30's from start to finish I've never had that problem so I'm afraid, with all respect, I disagree.

My veg room gets as low as 30 in the winter. One of my strains doesn't mind. The other, like I said, will curl up just like his when I transplant from the domed tray to pots. Placing a clear plastic beer cup over the clone fixes it within minutes.
A lot of things are strain dependent my friend, I'd bet my best mom that if he raises RH to 60 it will improve instantly. Nothing to lose, eh, OP? Much safer to try that first, rather than immediately messing with your nutes, or other stuff you can't undo.

Like other have stated, that plant is young, and looks FINE. Let's not shove our foot up her ass just yet... but wtf do I know

 

[HeadyPete]

my rh is 20s in winter and I never see that....

 

[realspringer]

well said K....Im still laughing my ass off at your way of putting that one....lol

 

[Weedhound]

Jones mentioned it back in a previous post regarding this same issue as well. Thanks for the info guys.....I'll ask someone I trust but I must say I've never had a problem unless rooom temps were also cold.

thanks again.

 

[Koskesh]

well, lol i'm not saying they're wrong, or lying about their RH - i do see some LOW rh as well sometimes.. just saying i have a strain that does that, so why not try the LEAST INVASIVE surgery before the triple bypass lololol

respect to all, i'm sure you know your shit... dude if you don't wanna try upping RH just move the light up a bit so she ain't so dry. did the people saying they have low RH say what kind of light they have and how far away it is? everybody's room is different as well... ok i guess that's more than enough for my 2 cents lol

I have no idea what you know. Here's what I know. This poster wrote in and asked about a problem he felt he had. I agree there is an issue. You don't. so why do you keep coming back to this thread? You've stated your opinion..... and now again.....rudely........so thanks, appreciated; all cured; now please go away or at the very least have the decency to let others post their opinions without the beneft of your judgements on them.

thanks.

PS....at any point in time if Nathindica would like me to I'll stop posting here......i'm not here to argue but don't care to be mocked either.

 

[realspringer]

hi HP...I dont disagree with your claim one bit..I was only trying to bring out the fact that different enviroments have different affects on certain strains...The exact plant/clone from a mother grown in identicle system and all things being equal...other than set and setting..will more times than not ..exibit different "anomilys" for lack of better words.. 20% rh ? Do you have to manipulate your traces for the additional transporation rates in that kinda enviro??? Just curious..cuz I've had to"get stingy" with them a time or two as compensation?? peace..rs

 

[Koskesh]

lol didn't think i was being rude, nor mocking you mate. And i was responding, as you said, to the "problem he felt he had".

Not sure what you're so angry about, but you're the one being rude, weedhound. But since you just kicked me out of someone else's thread I must be missing something important - guess I'll be going

 

[Weedhound]

I apologize but I took the foot up the ass thing as more than a bit rude.......especially considering said poster wanted to try what Pete told him and not just leave it ......which is well his right with his own plants. And I don't have the slightest right to kick you off anywhere so I apologize for that as well....it's not even my thread so I'm full of shit there all the way. Of course you can post here. You have as much right to post as I do. But rather than answer with a rude joke, designed to demean someone, why not just say you don't agree instead of foot up the ass crap in the future? I would certainly appreciate it.

 

[Koskesh]

yeah you're probably right lol, sorry if my jokes came off rude - anyway no hard feelings.

time

i still say up the ph a tad, rh of 30 shouldnt be problematic unless its a very slim leafed sativa.

 

[Nathindica]

Im glad everyone is getting along again.

Now, time to stir up this thread again.

I put 1/4 tsp per gallon epsom in my rez. I also put it under a 600 HPS so hopefully see some faster growth. What I got...

... is a calcium deficiency. Camera is charging now, so I'll be posting pics in a couple hours. Looks like a pretty definite Calcium def. to me. Started on the lowesst leaves and is working its way slowly up. might this be from the upped Mag in the epsom locking it out?

So upon first sign I emptied the rez and put a gallon of distilled and a gallon of tap in there. (i only had one gallon of distilled) I set the pH to 5.5 because on that little colorful pH nutrient uptake chart I have it says calcium in hydro is absorbed at pH levels from 5.4-5.8.

I let the plain water run for lights off plus a couple extra. So plain water ran for about 8-9 hours. Then i added lucas at (0-2.5-5)

Was I right to put nutes back in to get everything back on track? Or should I let plain water run for a day or two until symptoms subside?

I still have the soil mentality "when in doubt flush it out" Is this the same idea for hydro?

plain water or properly balanced nutes to fix the issue?

 

[Nathindica]

oh and just to clarify about my pH...

I set it to 5.5 because the plant moves it to 6.3 about 24 hours later. Is this normal fluctuation? Does this kind of fluctuation mean the plant wants more nutes? Am I right in thinking that kind of fluctuation means the plant is eating more than it's drinking.. therefore... hungry?

What kind of fluctuation am I looking for in a 2 gallon rez waterfarm with 1 plant?

And arcticsun- And according to a pH chart I have... 5.5 is within the acceptable range for hydro... is this incorrect? Since it looks like Mag and Cal are absorbed on the lower end of the scale, I set my pH to 5.5 so the plant gets everything it needs in the swing up to 6.3

I'd really appreciate some comments on the way I do things, as it IS afterall my first time with hydro so I'm trying to build up a routine. Anyone grow by pH fluctuations here and want to enlighten me?

 

[Nathindica]

PICS...

Besides the possible cal deficiency, This plant just doesn't seem to be as happy anymore.. as you can see in the pics. Perhaps its the shock from moving from 4 cfls to 600 watts of hps? The light is over 2 feet away...

However to cool that light I have a cooltube and a 6'' vortex in my cabinet... which pulls a lot of air through the space. Could this be from too much ventalation? too my air passing too rapidly around the leaves? Is there such a thing?

Anyways the real problem here seems to be in the rez. It seems like the problem accelerated a great deal when I added the epsom to try and fix a magnesium deficiency.

Thoughts? And it would help if anyone could answer ANY of my questions in this thread. I know a ask a LOT of questions... I'm learning! I really appreciate everything everyone has contributed so far here. I've learned a lot from the dialogue.

Anyways let's see if we can get this Jack Herer happy again!

 

[glacier]

cal deficiency? are you sure? to me it sort of looks like you've had some water splashing on your leaves, i've seen it happen with my waterfarms.

those pictures dont really look that bad.... how are your ppm's? has your PH been swinging like that for a while? or is it a new thing?

 

[Nathindica]

Unfortunately I don't own a ppm meter for now. Only a digi pH pen. My pH has been swinging like that since I put the plant in the waterfarm. Almost like clockwork right now. 5.5-6.2 in 24 hours.

I soaked, rinsed, soaked, and rinsed again my hydroton to make sure there was no dust left. I left it on for 2 days just to make sure no dust from the clay ended up in my rez. So its not that...

Do you find that when you take a plant from flouros to HPS it gets a little unhappy and saggy like mine in the pics? It doesn't seem like it's 'reaching for the light' anymore. Maybe a little intimidated? How long does you light shock usually last if any at all?

And I've been watching the leaves go from slightly discolored to seeing these spots. So the progression tells me its in the nutes, not just some splashing. Although I haven't used a waterfarm before so I would'nt know what splashing/burning looks like....

i had plants from an old grow that looked bad from a little water splashing on the leaves. it looks very similar to your problem. droopy leaves, and some rusting. it was a combination of splashing on the leaves and PH issues similar to yours that caused that for me.

 

[Weedhound]

Didn't you mention to me that you washed the dust off your hydroton but didn't pretreat for proper ph? If so, i'm sure thats your issue and it will continue until the hydroton finally gives in.....which takes awhile.

keep adjusting it back but do a LOT of res changes because you can get a build up from too much ph adjusters and that will cause its own problem. Changing the res often will help with this and also help treat the hydroton as well.

Your theory is not correct I'm afraid....usually a rapidly rising ph in a system will indicate nute BURN, not hunger. So I would also drop your ppms at least 100 and see if that makes a difference as well.

good luck.

 

[Weedhound]

Generally you have to readjust and pretreat your hydroton AGGRESSIVELY for about a week......just one of the little tidbits about hydroton that I dislike.

How close is your hps to your plants? could be heat issues in there as well.

 

[Nathindica]

When I soaked the hydroton it was in pH adjusted water. I didn't realize it would take so long for hydroton to stabilize. Hopefully I'll see it calm down soon and stop jumping around so much.

My HPS is about 2 feet away if not a bit more. Haven't measure it precisely, but my eye tells me its a bit more than 2 feet away. Even with the cooltube that 600 puts out a lot of heat. it gets up to 78 F in the cab but the vortex has to be full blast to keep it below 80. I'm thinking of downgrading to a 400 soon.

Sorry weedhound but I just need some more clarification on that pH/feeding questions. From my understanding, pH and ppm move in opposite directions. As ppms go down, pH rises. And of course the inverse is also true. So if that's the case... doesn't rising pH signal its eating more than its drinking? If what you're saying is true... I'm just completely lost and confused on this whole pH flucuation thing.

If the plant was burning... wouldn't it be taking in more water than nutes...causing pH to fall?

and again THANK YOU to everyone who is helping me out in this thread.
