Neut burn?

[Jamrasta]

Is this nutrient burn or something else?

LED light.
sorry I can’t remember the strain but it’s either
Cheese or Northern Lights
Currently week 8 or 9 veg.

It’s the first time I have used this bio feed. I got it as a gift from a friend so thought I would try it out.

Unless someone tells me otherwise I think I need to flush with plain water and remove the yellowing leaves right?

I followed the dosage suggestions on the bottle too btw. So I’m not sure if neut burn is what I’m looking at here.

thank you in advance :-)

Can you take pics in normal light? Really hard to make out the issue on the leaves.

[Jamrasta]

Here you go ...
I took the worst leaves off already but here’s photos of them. And how it looks now I removed the bad ones.
They have only been off the plant around 10 mins

I say it to much, whats the PH? To me this reads as a root/PH issue and about to get worse.

I hear you man, Rwise you can't ask what the ph is to much, cause that's normally the problem, either that or bugs, most of the time.imo

D.A.A.S.69 And thats the other one, if the leaves are clawed look for bugs.

I need to invest in the PH reader pen.
I’ve been using the strips which change colour and it’s usually between 6 & 7.
although not accurate enough I know.
I shall do another check now and let you know what comes back.
thanks for the advice.

I just dropped $308. on a Bluelabs combo meter, now to learn how to use it, LOL

I just noticed there seems to be a strong smell of sulphur. Like I have a match stick in there or something.

I never noticed this smell before. Is that something to worry about too?

If you got everything else pretty much right, like ph, an stuff, I'd say it looks like led, bleaching,
What type light are you using and how close is it?

It’s a 600W full spectrum LED light.
Around 50-60 cm above the top leaves. (It’s what the manual said)


other info -

Growing in a coco / perlite mix

I don’t water the plant according to a schedule, I do the knuckle test and water when I think it’s needed.

P/H strips are still showing as ok levels. I tried a few and all show same result.
6/7 ph is ok for coco soil right?

I might move the light a little higher just to see if anything changes.

Good plan with raising the light

[D.A.A.S.69]

In coco you want your ph between 5.5-6.5,
6.0-7.0ph, for soil.

[D.A.A.S.69]

Are you watering to runoff everytime you water?
In coco you need to check your runoff water too.
