Help! Possible nitrogen deficiency I think

[Scottishweed]

Is this a start of a nitrogen deficiency? Paler limey leaves, yellowing(ish) of tips?

If so would I just up the nutrient feed slightly? I lowered the feed due to a white widow showing signs of overdose, (really dark green, fuller rubbery looking leaves) I hope my diagnoses is correct but if I'm wrong can some one offer advice?

I would highly doubt it's a nitrogen deficiency this early in, most people don't start feeding until the plat has a few sets of leaves.
What soil are you using? It could be a little burn from nute overload.

 

[Scottishweed]

@Billpopy79 It's in coco, I've only used rhizotonic and calmag

 

[oldsmokey]

I'd that soil with coco ?

 

[Scottishweed]

In all honesty it's cheap coco I'm still waiting on my biobizz coco mix

 

[CagedApe]

I'd that soil with coco ?

Coco/perlite mix by the looks of it.

 

[oldsmokey]

It looks more like soil or a mix.

 

[Scottishweed]

The fact it's a cheap coco could and may be the cause of it.(I did use ph'd water to hydrate and rinsed it with ph'd water with rhizotonic)

I ordered a bag of coco with my tent kit but the company was waiting on a delivery and said theyd get it to me asap. That was 3weeks ago. So I have orderd another bag which is due tomorrow

 

[oldsmokey]

I don't what to give advise I don't grow in Coco I use promix. It is important to know your medium do you have the bag.

 

[Scottishweed]

Erm no, but if I'm out tomorrow I could prob get a few photos of it

 

[oldsmokey]

That would probably help. I would treat it as soil and at this point not much for you to do make sure it's dry before you water again.

 

[Scottishweed]

Ok cool that's what I shall do. I've left them a day or so so theyll be due a watering tomorrow, top inch or so is dry and feels kinda light. Should I just use plain Ph'd water or should i use a reduced strength ph'd feed of Canna a+b, rhizotonic?

I'm currently reading some of the completed grow journals again.

Once I get mine written up I'll get it up on here

Cheers guys

How often do you water

 

[Scottishweed]

About every 2 days, I did overwater to begin with though

 

[oldsmokey]

Every two days is to much I can tell from the pic it's wet and won't need water for days. If you have a empty pot the same fill it with the medium you used. Pick it up feel the weight that's a dry pot. That's how you check if it needs watering your pot should feel really close in weight just slightly heavier. You have to develop a wet and DRY cycle. No nutrients are needed at this time. This where it would be good to know what's in your medium.

Try that and I bet it will show growth soon.

Feeling a bit worse than a beginner here and for mistreating the ladies

That might be why the Triple G and the Cookies are taking off in comparison. They're left slightly longer between waterings. They went into dryer pots with less watering from the start and about 2-3x the size.

I'll try get a pic of the medium tomorrow but hopefully the new stuff will come in. In which case I'll repot in new stuff n water less.

Worst case if I DONT get my delivery (I live north north scotland) do I want to ph slightly higher or would 5.9 be ok?
and
Would I just use plain water til 3-4 nodes come in then start a reduced nute feed and work up from there?

Thanks again for the advice,

 

[oldsmokey]

Just water for now no nutes ph 6.3 - 6.5 the cotyledon Leafs will feed it for the first week or so. If they are yellowing then feed a seedling dosage. Would help to know whats in your medium. Do you have your nutes on-hand ready when you need them?

 

[Scottishweed]

I've got a few things to do ,today but will try get the info on the medium if the new stuff dont turn up.
Yea i've got the nutes on hand I got the canna-UK starter kit, a+b, rhizotonic, cannazym, boost and pk13/14

 

[Scottishweed]

Had a wee look in this morn, the colours sorta returning to the leaves although they wont heal they are looking a tad greener and healthier. Still no sign of my delivery so ordered more biobizz coco today with a rush on delivery.

Welcome to Scottish!

By “cheap coco”, I am going to assume that it wasn’t pre-buffered. Coco coir needs to be presoaked in CalMag to displace the excessive sodium and potassium ions held in it. Otherwise, it will foul up your intended nutrition. G00gle “buffering coco“.
