Claw & Dimpled Leaves Problems

Hi Guys,

I am having slight issues with my babies...

3 are k-train from GHSC & the other is Big Bang from GHSC.

2 of the k-train & the Big Bang are growing nicely in size but all have a dimpling/bubbling effect on the leaves, some of the leaves are pointing up (Canue shaped), some pointing down (Claw shaped), some twisted & others just look fine.

The other k-train is lagging behind in size but also has the dimply leaves, I would almost call them wrinkle lines.

My set up is as follows:

2 x 600w HPS placed about 12-15 inches from the plants
2m x 1.25m x 2.5m Budbox Tent
Carbon Filter + Extractor Fan with 4" ducting
Ocilating Fan running with lights on, but not off
20 Ltr Pots of Batmix Organic Soil
18hrs on/6hrs off
Temps range from 60 Degs with lights off to 81 Degs with lights on
I am not sure of my humidity as I don't have anything to measure with with?

From what I have read, claw leaf is caused from either over watering or over nutes. I water them with 1 liter of water (PH of 6.5) every 3 days or whenever the pot is light & have not yet used nutes as the bat mix is full of 5 weeks worth of goodness.

My ph was slightly off for the first few weeks as was using the cheap test tube ph kit, but have been using a digital one for the last 2 waters & both times ph has been 6.5.

Any suggestions please?

Tks

Sorry guys/girls...

Forgot to upload photos...

seems like a slight ph issue to me.. whats the ph of the soil? have you phd the runoff?

Thanks Flojo,

Am planning to buy a soil tester kit today, I have not yet
tested the run off either, plan to do this at next watering
which will most probably be tomorrow.

I am thinking of just flushing them anyway, I have 8 x 20 ltr pots so thats
320 ltrs of ph'd water :~(

Ahhhhh......

I ph'd the run off and it was 7.0.

The ph of the water I used was 6.4.

What should my run off be?

Thanks

you want the runoff to be in the neighborhood of 6.2-6.5

there lies your problem... flush em out with 6.0 ph water and you should be good to go

Thanks Flojo...

Will flush tonight, a shame as they have only been in the bat mix for 2 weeks,
I assume I will have to start using ferts once flushed as flushing takes all the
organic nutes out?

no it doesnt take all the nutes out, it does take some, but it never hurts to start slowly supplementing with nutes to make sure they are getting everything they need

thanks again flojo...

Should I do a full flush (3 x volume of pots) or
should I maybe try 1 x volume of pot and
monitor the runoff untill it is 6ish?

Sorry for all the questions

Hey Muff.

The thing I like about your grows is your concerns are warranted, but you have great looking plants that just need some tweaking. That's all.

This grow is a good street, and FloJo is right, right right!
Get that run-off sweet.

When I see these girls, I want to know humidity.
You need to know that as well.
...and the only thing missing from your 'run down' of the situation, is RH.

Is this a tropical environment? What is the RH?

The cabbages you have growing here look great, monsters in the making.
Lovin it.
But what is the RH?

Where are they growing?
Not on the path...

ya man id just flush em out with 6.0 water a liter at a time until the runoff is about 6.2-6.5 do this to all of em, then mix up some light nutes, ph it, and feed em so u know they are good on ph and have all they need

Thanks once again for your help flojo... Will recify tonight

Thanks also mammath... They do look like cabbages don't they

I have never thought of rh to be honest, what do I need? A dehumidifier
I assume?

I wish I lived sub tropical, they are grown in a xxl bud box with
2 x 600's...

One last question mammath...

What type of dehumidifier should I buy?

My issue is that I have my extractor fan running 18
hours a day and my ocilating fan for 18 hours too so
any adjustment of humidity will be taken out of the
text by the extractor fan?

Or am I just not getting it ?

Cheers

Yes, I think your humidity is right up there, on the high side.
You'll get away with that during veg but not in flower.
First, I would purchase a RH gauge so you know what it is inside your box.
Second, run that extractor 24/7. RH could be just building up over the dark cycle because of lack of ventilation.
All should be cool then once you sort out the PH issue.
Plants are going to be beauties.

You starting a journal on these ladies?

Hey Mammath...

I have just purchased a new temp/hum reader, it is currently showing at
55% humidity but it has only been in the tent for 10 mins, will report back
later :~)

From what I have read, I need 50-80% for Veg & 35-50% for flowering?

I have flushed two of the pots with maybe 4/5 liters of ph 6.0 water each
(They are 20 Liter pots) & the run off is now 5.9 & 6.0. A bit low, but I
plan to give each of them a 1/4 strength nute boost so will use ph 6.2 - 6.3
water with this to raise the run off.

Saying that, I'm not sure about the nute boost as I have only used 4/5
liters of flushing water so the bat mix should still be effective I would have
thought? It is supposed to be good for 5-7 weeks before nutes are needed.

I hate the thought of over nuting my babies, so think I will give them a chance
to come back on their own before I start adding things

I am pretty sure the correctly ph'd water is having an effect
as I have a El Nino from GHSC, she was only about 4" high
compared to the K-Trains being 12" high when I posted the
photos, but she was 3 times as stocky as them, she has grown
3 inches in 7 days...

Fingers crossed, she is going to be a beauty.





Cheers

You really want to see what the RH is during the night cycle when your fans are off, that's where I think it's been building up. Then re-measure with fans on to see the difference.
Your plants are super green so they're getting plenty of N. Have you been feeding them or just relying on the bat poo in the pot?

I have been relying on the bat pooh until now :~)

This is the one I have

----------

Plagron Batmix:

Bat Mix is the ideal natural potting soil. It contains bat manure, which is well-known for its unprecedented richness in nutrients.

Also contains white peat, baltic peat, sphagnum, irish white peat chunks, black peat, worm castings, organic manure and 15% Perlite.

Bat Mix provides your plants with everything they need, especially in the blooming phase.

Will last 6-7 weeks before any further feed is needed.

pH: 5,8 and 6,2
EC: 1.4 and 1.6

----------

I put the girls in the 20 ltr pots filled to the brim with it at
maybe week 4 from sprout... They have probably been in it for
4 weeks now.

All seems ok though, apart from the ph problem obviously.

I would just keep relying on the bat mix for now. They don't look like they need any more ferts.
They may even be running a little hot, fert wise.
Just flush 'em like FloJo recommends and keep us posted on their development.

Edit: I did notice you said your 600w's were 12-15" away. You may need to increase this distance a little because that's pretty close, and temps could be higher right under the light at the canopy.
This heat and light intensity can also cause foliage to freak out a bit.

Good call on the light heights, was thinking that myself... Some people say
1 foot above, some say 2 foot above?

It is pretty hot under there so I have moved them to 1.5 foot for the moment.

In other news, the rh whilst lights were on was 61% & the rh whilst lights were off was 73%. Ok, for vegging, but no good for flowering, will have to invest in a dehumidifier.

Two of the plants I flushed yesterday are showing huge improvements so hopefully the rest will follow.

Will post some pics tomorrow.
