WTF? Yellowing Leaves at Day 14 Vegeing.

[Baphomet]

Hi folks,

Just started my 3rd grow, or as I like to think, my first real grow after 2 trials

I germinated 4 seeds of each of the following strains:
Nigeria Amsterdam Seedbank
Sweet Tooth British Columbia Bud Depot
Hash Plant British Columbia Bud Depot

Ended up with Nigeria x 2, Sweet Tooth x 3 & Hash Plant x 3.

Once they'd popped, they had 10 days as seedlings under 24/0 CFL, then were transplanted into coco under 250w HPS 24/0 in an open room.

They were given 20% strength Nutes in rainwater for their 1st 2 weeks, and then supplemented with Canna's Cannazyme & Rhizotonic (my first time using thses two products). All plants also receive weekly foliar soakings with Rhizotonic.

Here we are at D14 Vegeing (ie. 14th day of Vegeing after 10 days as seedlings).
The plants were all transplanted into their final pots last night and were totally rootbound!
If this is what Canna's Rhizotonic is capable of doing to a plant in a week , they should put 'WARNING' labels on the bottle!!

The plants are now under 400w HPS 18/6 in my stealth wardrobe

Now for the question...
Why the fuck have I got yellowing leaves already??????????

I'm hoping this is due to the rootbound situation already mentioned, or is this a Nute deficiency already? Lack of Nitrogen?

I can't believe I can get this so early - can someone please tell me:
a) What I did to cause this?
b) How can I remedy this?
Thanks

the roots may be under developed or a nuet def.It appears to be a tossup. i alwaws plant a couple extras to examanine roots at signs of problems.

Are the leaves veins bright green?

 

[Baphomet]

Thanks for your replies octodiem
I just went out and had a good look at the leaves in question.
They look almost "bleached" and some have this bleaching in spots - almost like splashes...
All of the upper foliage is a lush green, so here's what I'm thinking....

When I transplanted them, I would have replanted them deeper, up to their cotyledon leaves. I would have then given them a Nute watering and also Rhizotonic to aid the roots. If this mixture were to get on the leaves through sloppy hand watering (because those bottom leaves are now resting on the coco due to the repotting) and to splash droplets on others, could this cause what I'm seeing?

If so, I think that's my problem nailed!

They were given 20% strength Nutes in rainwater for their 1st 2 weeks

What are the nutes? What exactly is in them? how much is 20%? You should be ph adjusting the fert water before applying to the plants.

Get a close up of a couple leaves/plant. All I see is yellow... which is a bizzalliontrillion things.

Possible nutrient burn . . .

Possible nutrient burn . . .

You may be going overboard with the nutrients, different strains have varying requirements or 'sweet spots'.

If so, foliar feed with pure water (or seltzer) to help flush and be light with the nutrients for a week or so.

Also, whenever you have an issue which puzzles you, always check pH first. An imbalance there can resemble many different problems, and cause nutrient lockout.

Good luck.

they look a little droopy too - it could be caused by overwatering. (better pictures would sure help!)

be sure to let the top 3 or 4 inches of soil dry out before watering/feeding again.

I don't mean to hijack the thread but those look huge to me for 14 days. Is it that they get 18 hours of light? 18 is far more than my outdoor plants get so maybe mine grow slower. I also see people starting theirs in what looks like rich soil yet they get big very fast. My recent attempts at starting in slightly diluted Happy Frog soil caused my plants to stretch and fall over and still haven't really filled out even though they're on their 4th set of leaves. I believe it was too much nitrogen, too soon for the strains. I just wish I could get mine to grow faster generally and it seems like so many others show pics of young plants that are just taking off.

Anyway, hope you get your problems worked out cause they look like they have a lot of potential.

 

[jello]

to me,..it looks like overwatering (and perhaps the begining stages of a nute lockout....)

 

[Baphomet]

Thanks everyone for the input.
I've just taken a picture of the 2 worst lookers to show more detail.
Overwatering is definitely a possibility, as when they were transplanted into their current pots and placed in their buckets, I gave them a thorough watering until I had about 10% run off, and then let them sit in it overnight

Any more ideas guys?

Hey there, thanks for your comments - here's my lighting regimen:
Once my seeds pop, I transplant them into coco under CFL light 24/0.
After 10 days as 'seedlings' they get transplanted to bigger pots and start with 250w HPS 24/0 for 2 weeks (I move the light closer to the plants as they harden off).
After that, it's the final repot into their flowering pots and the lighting schedule changes to 400w HPS 18/0.
Obviously lighting goes to 12/12 when I start to flower them...

I'm thinking of trying a 12/12 from seed next to see how that affects my harvest (for personal enjoyment only, I'm not a cash cropper so I can afford a bit of experimentation).

looks lik it cud be to much water on the transplant? i also have seen someone,wen he transplanted he waterd in a circle a few inches from plant,and did not wet entire surface,results,plants were growing fast,,i tried it ,seemed to work better then weting entire surface,strange...if plants turned funny after ,they were transplanted and still waiting,to dry,to much water..the amont..especially if ph,is not exactly on.looks lik those pot wud a decent amont of water,wen soaked,try cut back on he amont,instead of soak,keep track in pints or cups,adjust by one at a time,down until plant looks well,i do it all the time if needed...maybe cut the soak amont in half? thats my take on it,check it...peace moon/

How often are you watering your plants first, and have you been testing the ph?
your plants look overwatered for one; if so ntirogen is poorly absorbed in soggy soils.. what kind of soil mixture do you have?
You have both nitrogen and magniseum issues, why? I have no clue yet could be either ph issues or your not feeding them enough

how often have you fed your plants?

And since someone here mentioned it; different strains requirediffernt care; it's harder to grow different strains together I have done it; every grow I did I grew out 2 or 3 strains per grow and it got a pain cause they all had different requirements; if you want to grow more than one strain grow one that are near the requirements of the other.

 

[Baphomet]

Thanks MynameStitch.
I've just followed the link at the bottom of your post to your "Complete Guide".
Here's the 1st thing I saw...
"DO NOT get soil testers, those are the cheapest junk I ever seen and do not give good readings, so you cant rely on one of those."

Guess what I've been relying on...

I'll get some ph testing papers tomorrow when I'm checking the price on digital meters.

Never really gave too much thought to the different needs of different strains when growing together - but now that you mention it, my last grow was White Widow x 2 & a mystery grow which turned out to be Nigeria.
The WWs all looked a little unwell at the end (one's fan leaves had gone completely purple), but the Nigeria absolutely flourished and went wild under the same conditions!

Appreciate your guidance.

 

[Getawaymonkey!]

that looks like a Ph problem to me, but were talking about a coco grow right?

 

[Guest]

What is that medium your using? It doesn't look like it would drain well...

 

[Baphomet]

My medium is 100% Coco coir and is hand watered.

 

[Guest]

Ah... well I hate coco... you can skip all the troubles (probably the issue you have now) by just getting a premixed soil, but I guess each to his own. Heard good and bad things of coco.

 

[Guest]

i had the same problem..mypost is the magnese or overwatering def...i was told the brown spots on the leaves are "dead" spots when the tissue couldnt get nitrogen fast enough. could be typing it a bit wrong but i thought our plants looked similar. you might check it out and see what they said.
