Female WW seedlings need to be saved

[gertrude420]

Ok So a long overdue but nessecary update !!

So i washed the soil of the roots, and stuck them in this hydro setup... with 100 watts of flouros for about 10 days.... Then i flipped on the MH 1000... It took them awhile before they adjusted and started growing roots... and after 1 week of MH and plain water I added Dutch Nutrient formula. 500-700 ppm in ea bucket, and ph down so ph is between 5-6 ph...

The 2 big plants are sweetooth #3 clones
The rest are white widow female seeds seedlings.
I only lost 1 white widow through this mess!!!

So here are the pics...

There is some sort of deficiency, havn't taken a look yet on here to figure it out...

Maybe something to do with the p.h. so i will make a thourough check for ea bucket, and the ppm of nutrient solution as well.

The plants are looking far better Gertie, I take it removing the plants from the soil and putting them in the hydro buckets had something to do with it.

I'm having some serious trouble with my seedlings right now, their burning up and they havent even had any ferts this really blows my mind, its from the bottom up just like fert burn but they've had none at all, I'm kinda stumped I'm going to have to start a thread after I write this.

Glad to hear that they perked up they look 100x better, Peace

ya its prob the same thing as me... hows your ph... i just realised that for the longest time of me growing i would always think of the nutrients when i had a problem, when infact it was usually the ph all messed up from organics and what not..... something to keep in mind....

I don't know I need to check it it kinda slipped my mind, waht ph are you using for you dro?

I think it might be chlorine related you can smell it in the water.

 

[gertrude420]

chlorine evaorates doesn't it ? once it comes out of the tap

i got to get an exact ph reading tomorrow morning.

lots of people recommend leaving water out for a night or even 24 hours for the chlorine to evaporate, it takes a while.

Has the new growth gone almost completely yellow? Sorta looks like that but pictures can be decieving. I think you might have both iron and manganese deficiency. This is my first time seeing mn def in the cannabis infirmary. If ph is ok and your adding these micros, check for root damage.

hey gertrude , glad ya saved them . take it slow and read and ask questions till ya know were all here to help ! many blessings , hidingtree

I don't know if your asking me but some of the new growth has started to go yellow but I switched the water to botteled spring water last night with a little expert gardner bloom ferts and I think their doing better but time will tell. The roots look fine they were in great need of a transplant and they got it last night, so time will tell for mine.

As for the chlorine I used to have fish and yea if you set out most tap water after 24hrs all the chlorine will evaporate, this tap water took two days and I'm still not going to use it just to be safe.

Peace

ya the all the new growth and fan leaves are completly yellow.. with the veins still being green. Im not sure what the P.H. Was at before...

But yesterday I topped up all the buckets with fresh tap water, added Ferts. to 600-700 ppm. and adjusted P.H. to between 5.5-5.8 , today i check and the P.H. levels in the buckets go from 5.8 - 6.2 , Is this normal, that they change? ... I will re-adjust sometime today or tomorrow to 5.8 again... is that what it should be at ? Whats optimum... I am pretty sure they are looking like this from the incorrect P.H...

I will do some research on here and take a look around.....

 

[gertrude420]

Can Anyone help me here ?? please ??........

is this the right ppm.... is 6.2 too high ?

Are your micronutrients chelated? They will say iron edta, iron dtpa, etc... rather than iron sulfate. (sulfate forms) You got a micronutrient problem like I mentioned in a previous post. Check your root tips and see if they are white or brown. Damaged roots will show as iron def. What is water temp? Below 68f will also cause this. Or, You may just need more micros. Cal mag plus will cure a iron def as well as other micros.

Hi Gertrude, Im glad the transfer from soil to hydro worked out 4 ya. Sorry to hear you lost a WW girl in the process tho, but im sure the others will nicely make up for it.
I'm not a hydro grower, but Ive found some charts in a book that might be useful for you. The book states that for hydroponics, the pH is best in between 5.2 and 6 max, so 6.2 might be a tad high...
Here is the chart of nutrient absorbtion vs pH for hydroponics:

Here is the chart for soil:

As for ppms, Im not entirely sure, but i remember reading that there are diff measurements depending on the meter you are using (Hanna, Truncheon, ...).

I see the DNF website only gives suggested EC and not ppm... Im sure there must be some converters out there.

However Ive had a look on the Canna website and the recommended ppm for veg (with a Hanna meter) is in between 500 and 700, as you correctly stated, and with a Truncheon meter the ppm should be in between 800 and 1000.

Now these numbers are guidelines for Canna's Aqua nutes, so I do not know if they can be applied for the Dutch Nutrient Formula nutes, but I would think it would be in a similar range.

HOWEVER you must bear in mind that these values given out by the manufacturers are based on use with RO water which has a starting ppm of 0.
There is no tap water which has a starting ppm of 0 so this must be taken into account when you prepare your mix.

Mandala Mike has written an excellent thread in the Mandala Seeds forum about this and fertilizing, i highly recommend reading it as it may well help you with your fertilizing issues, here it is: http://www.icmag.com/ic/showthread.php?t=13689


Hope you find this useful, and good luck with your grow!

Peace
