Hello icmagers ,
New updates in my ph updrifting adventure.
Even if the 1,6 EC sounds too hot for so young ladies
my ppm fall from (1120 - .7) to (1080 - .7 ) and my ph
readings continue to updrift so based on
EC down ph up = weak nutes & that my ladies look that they can
handle 1.6 EC and that tjo with 12-6-3 per gallon take readings of
1,6 EC while i am taking the same readings with 8-4-2 i decide to
add more nutes to my res.

In 60 litres(almost 16 gallons) i add 24-12-6 GMB bringing down my
ph to 5,6 from 6 and ppm at (1280 - .7) or EC @ 1,8.
I know that this levels is By FAR extreme for these ladies but
i am tired chasing my PH .

I hope that they will make it and if they die i will switch to soil again.

Also one of my airstones almost stop bubbling
and i will replace , hydro is a hedake !!

Very short internodes these Shiva Skunks
Pic updates follow .






That's it for today , c u

[Mr.Jones]

looking sweet over there!

i just love to see plants growing in dwc

[tricky1]

Looks good.
I say to stop chasing the pH and start to grow plants.
As long as they do not show any deficiency and they are growing nice....

[erwingruber]

Unfortunatelly this ladies like me to chase something !!!

The ladies growing in RDWC with GH 3 parts in 16 gallons
@ 8-4-2 + a little bit more (24-12-6 to the 16 gallons)
The current readings of my ppm meter is 1230ppm(.7) downdrift from 1280

My ppm meter is reading a bit of high (after calibration) taking readings from
Lucas 0-8-16 @ 1610(.7) and 2,2 EC starting from R/O @ 10 ppm
while it must read 1400(.7) and 2,0 EC .
In the oposite position the calibration solution of 1413 read it exactly 1413 .... anyway.

After getting partial control of my ph raising my EC based on
weak nutes=little buffer capacity i have the folowing issue.

The sign's is there before but they was very very slight hardly to notice ,
the last two days i have some spot's on some of my fan leafs and they spread slowly from bottom to top from older to newer leafs.

I was checking following sticky and i think that i have a Ca def or a nuteburn

some pics to help you

Hello icmagers ,
I am here with some updated pics and as always my request for your
Help.

Today i put in my res about 10 litres of fresh plain R/O water my ppm
was @ 1204(.7) downdrifting from 1287(.7) in 3 days.My ph is more stable now and i try to keep it updrifting from 5,3 to 5,9.

I will post some general pictures of my girls that look almost good ,
but in detail i cab spot severe damge in the older-lower leafes.

As i describe in the above post based on the stickie i think that it is Ca defiance or nuteburns and i need your help here to indentify and solve my problem.

As my first step i lower my ppms adding plain R/O water to 1046(.7) a little bit lower form 1.5 EC (maybe my ppm is making high reading as i descipe in the above post)

My mother plant (Shiva Mother) is far behind from the hydro ones now , I can spot something on her new growth but i do not worry about her she is a fighter i will post pictures from her too any diagnosis it will be helpfull.

Enough talking let me let you help me with some photos.

possibly cal mag. looks like zinc to me. are they in veg? some potassium could help for the zinc def. if im not mistaken.

cheers, n goodluck.

today i saw in my grow a terrible mistake...
my res-not the controller- had almost 0,8 ec and i thought
was near of 0 ppm.. that was from last year because i never clean it. all my readings was wrong after that i notice.
2night i will change my water. i will tell you my readings
after that.!

by the way your plants looks much bigger. about the def you have
im almost sure that is cal-mag.i had it last year and was exacly like yours.!

cheers

[erwingruber]

@ dgkish
Yes the plants is in veg and yes probably you are right in both cases i must fix my cal mag issue.
@tjo
i cannot believe it !!
The remainings of nutes give 0,8 ec this is a lot of nutes.
Changing water is a pain in the ass for me too.

Well Hello icmagers ,
The plant's exploding with the roots inside the water , i leave them alone for 24 hours
and i was amazed from the one days growth.The Shiva Mother looks so small now

My girls drinking nutes like crazy they drink 100+ ppm in 3 days .Today i give them back 3 gallons
of fresh R/O water and i raise my EC @ 1,5 with fresh nutes.

I was planing to instal my scrog screnn 2 days before but i was away from my girls so i install
it today.The positioning of the plants is not ideal cause they are on the right side of my screen
so i will train them all 4 to the left.I believe that i do not have more time until 12/12 cause my screen
is almost ready , idealy i would like to see some female sign's before i filp them to 12/12 but will see.

Enough with the talking , i have some picture updates

The girls before the Scrog screen ... they have very very short internodes





The defiance is here but lighter i think.

Scrog screen installed



And the removed leafs with def signs

That's all for now , i'll be back with some fresh training pics soon.

I'm glad you're happy and the plants have recovered nicely and grow.

Today i chop down my balcony Big Bud from sensi and i have a pic for you .
This plant was the worst from 18 cuttings and it is going to the trashcan ...
but i change my mind and give it one opportunity in my balcony.
Survive from temps over 113 F /45 celsius drinking alone 6 liters of water on the hot days.
