Seedlings, watering and nutrients

[Adriaanoo]

I will have my ec pen on Wednesday.

I am attaching other picture that I have but it was done witb flash. I am at work now so cant take any more.

2 main leaves are turning yellow.

I am worried about doing another run off.

Should I mix 2ml of a b in 5 littre and spray around the seedling lets say in a 1 or 2 as I already watered them to run off?

My temperature is high as well 31-32c degrees but this will get down tommorow as I have extra setup coming. Maybe is not the temperature.

Humidity in my tent is around 50%

Hope I can help them

Ahhh now with a better picture it doesn't look to me like she's dying through lack of hunger!..keep as you are with the nutes.

Could she be getting burnt?


600w HPS is a little much for the stage they are at... how close is the light to the girls?

I would reckon burnt as well. Really need a decent photo. If so adding more nutes would be bad

Best you can do is flush her with 3 x pot volume of pH'd water and reduce the nutrient concentration.

1 meter away bro, I know that temp is really high but at first it was 39C so I managed to get it down to 31-32C few days ago.

After the run off yesterday night leaves started to curl down, maybe stress or lack of oxygen not sure

[Adriaanoo]

The thing is that yesterday was the first day I gave them nuts. One of them is actually looking fine, maybe a bit light burn but looking good.

At 39c it could be the damage was done then...

I'll leave you in the capable hands of Jumper who has a lot of experience with EC/PH numbers

Got this pictures here, maybe now you guys will be able to tell more.

Thanks

I have had temps that high, so I would not worry there. Obviously being under 30C would be better.

Maybe keep off the a+b next feed and just use rhizotonic and see what happens from there. pH'd to 5,8.

The pics don't make it easy to see which way she is : burnt/hungry. Still learning toward burnt.

Edit : the 1st pic looks like she is burnt to me.

Do you mean burnt from light? Is it because of high temp?

If light burn then what can I do to avoid it? It is already over 1m from the plant

Hey

No I was referring to nutrient burn.

In coco fortunately things respond nice and quick. So I would try the above and check back tomorrow.

Try and keep RH in the 50s if you can whilst she grows roots.

Generally I would be wanting an EC of 0.2 at 5.8 right now. Most of that will be rhizo.
