Which deficiency is it??? Need Help Please!!

[Nikolaus]

Hey guys anyone call tell which deficiency is it?
Started first with the older leaves. They're getting yellow, curved down and the veins are still very green.
I managed to get the temps and humidity okay. Watering every 2 or 3 days for now on...
Please help!
Doesn't seem like Mg deficiency to me...

Is that happening more at the top of your plant then the bottom?

Hi all !!!! :thumbsup:

I would look at a Zinc or Potassium problem myself.

Second post i seen in problems using Bonsi soil, I'm not sure about it but it looks like clay to me.

Maybe this will help http://www.rollitup.org/view.php?pg=faq&cmd=article&id=37

[Nikolaus]

The tops are fine, just the older leaver are turning yellow.
I thought about Zinc too, but i'm not nearly sure.
And they're flowering, so I think they need help pretty fast...

Test your runoff pH immediately!

[Weedhound]

I agree with Stinky the issue has to be ph. Good luck.....those are some pretty unhappy plants.

[Nikolaus]

Guys, I ran to an aquarium shop and got the ph test.
Well, you're damn right. The ph indicates little above 5!!!
So i got organic shell calcium to correct the soil ph.
Should i flush them all before the calcium??
Is that the right way to do it?
Thanks, i'm just waiting for a reply to save the babies!

[LolaGal]

I'd Wait for WeedHound or Stinky before you try anything. Hope they get better soon.:)

Follow the directions in here EXACTLY.
Your low pH has locked out all the metals. That's why it looks like a REALLY bad Mg deficiency.
When the soil dries out from the flush and pH adjustment, get that plant into a larger pot of an unfertilized potting mix such as promix that has plenty of lime in it, and give it tap water at pH 6.7-7.0. The soil in that pot has had all the lime used up and you are now seeing what the true pH of un-buffered peat is!

[Nikolaus]

Thanks!
Well, i done the flushing and tryed to increase soil's ph. Should i wait two or three days than replant it?
Actually the pots i'm using are pretty large already.
Isn't there a problem to change pots during flowering time?
I mean, i just add new lime mix soil to the old ones? Cause the roots are already all the way to the bottom...

[Nikolaus]

Just with the flushing and the calcium the plants woke a little happier this morning.
I'm going for the mix soil right now. Are you sure there is no prob on transplanting during flowering/growing period? Don't forget those are automatic plants.
Have a good weekend!

You can transplant during flowering, just need to not stress it.

I just transplanted my flowering plants are there doing awesome.

[Weedhound]

I agree.....plants benefit from good, fresh QUALITY soil no matter what age or stage they are at.....just be very gentle with them.

[Nikolaus]

I did it yesterday, i tried to be very gentle.
Will they stop growing for a day or two?? Should i water them more constantly right after the change? For a regular plant that's a hit.
The pots are way bigger and the new ph is 6.8 :)!
They smell quite good.
Any other advices?

[Weedhound]

They may stop for a day or two while they adjust. When you water or feed nutes, keep the ph at about 6.3-6.4 on anything you put in your pot. And keep checking runoff every few times. Plants are living things and they change......as does their conditions. Watching what they do in response to different things is what learning to grow is all about. :)

[Nikolaus]

okay!
Actually i guess the tranplants were quite well, except for one of them which lost more soil during the process. Those leaves are still a little down, but i hope she recovers.
The water here has a ph of 6.5 . Is that ok? I can buy mineral water for the 6.3 ph, but i guess it's not very good for it's minerals...
When should i give them nutes? Is a 10-10-10 alright?
Thanks man, your really helping!

[Weedhound]

Ease stress on them until they come back......just regular water and easy lighting; then re-introduce things slowly. Sick plants are like sick people.....they need special care.

[Nikolaus]

They're doing fine, except for that one that i mentioned. Almost all the leaves are down, some of the bigger ones are even burned.
I don't thing she'll survive. It's been 2 days.
Should i chopp her off so i can still have 3 or 4 joints out of her? Or should i wait a little longer...?
Hard decision.

[Weedhound]

Ok so two are doing fine and the one you had a bit a root trouble with is not....is that correct?

If the plant looks worse than yesterday (you said its been 2 days) then I would call it and harvest before she rots. If she look BETTER or the same as yesterday I would wait.

[Weedhound]

Also I just found out from Stinky that she feels tap water ph'd to about 6.6 is the lowest she will use ph on soil......I personally go lower but she's the one who knows a LOT more than I do so go with the 6.6 as Stinky says. ;)

[Nikolaus]

Unfortunally she's way worse...
Actually i posted 3 pics, but there are 6 plants living! 2 out of them are midgets if compared to the other 4. I guess that's genetics.
The fact is that the one which is dying lost too much soil. She's worse than yesterday.
I'll find out water ph again and tell ya right away.
So harvest time for the baby???

[Weedhound]

If you see this plant continuing to march downhill as you are saying.....I'd dump it even with proper ph. She may have contracted some sort of root disease or fungus and I'd get her out of your growroom if she looks that bad.

Also consider a good root product like Cannazym and/or sensizym (sp?) for your next grow to keep roots in their best condition.

Glad to hear the others are ok......sorry about the one.

[Nikolaus]

Tap water ph is 6.5 even.
I'll keep using it, guess it's better than mineral water full of stuff they do not need.
I also leave the water resting for 3 days before using it.
Just waiting your reply to harvest... :pimp:

[Nikolaus]

Thank you for your concern...
It's like a lost in the family. You probably been through this already.
I'll give her more 12 hours to get better...
