HELP! Problem with the plant

[szaqal007]

Hi
First of all sorry for all the language errors that may occur. Please be patient with me.

I have a major problem with my plants. The leaves are dying and I dont know why. First leaves are those on the lower parts of the plant and its progressing up. And plants stopped growing.
I bought good soil (with fertilizers) + coco + perlite, give them 16h of light with Spider farmer SF-1000 in a growtent 1m/1m with fan to move the air + CO2 pad.
Watering twice a week (adjusted to 6.1 pH)
I've had the same situation with hydroponics before.

Please help, its driving me crazy. I've wasted 4 seeds already because of the same problem

That's progressed pretty far man. Like really far. No thoughts honestly. When did this start? Maybe wait for another opinion. CaptainWiese91 any clue on this?

[quietlybinary]

How much of your mix is soil, how much is coco coir and how much is perlite? Are you using any nutrients aside from the ones in the soil?
My impression is that they are lacking nitrogen because of the coco coir.

[szaqal007]

50% soil, 30% coco, 20% perlit
First grow i've tried hydroponics and... same result.
Second, in soil, I've used Canna Vega and it was the same.
This time I've used just the nutrients contained by soil (because I thought that the problem is nutrient burn) and it happened again.

Should I try to aply nitrogen?

I'm going to say what i think happened is soil had nutes right? Over watered and how close is that light? Once the tap root hit that soil with the ferts in it i think that it fried the roots. I'm sorry that it's happening but something is wrong with the mix of plugs and soil maybe light to strong and close? Are you using the same everything as the others you lost?

[szaqal007]

I water the plants twice a week (water pH 6,1)
Light is 1 meter away from the soil

I agree with quietlybinary looks very nitrogen deficient. I'm sure there are others in here with way more knowledge than my self. Also when you say good soil, could you elaborate on that a bit. What kind of soil and what fertilizer ratio. Another thing you could do is check the ph of your run off water. May not tell you everything you wanna know but might help? Best of luck

[CaptainWiese91]

Doesn’t look like a deficiency too me. But again I’ve never growed with coco.
What do you mean when you write; good soil with fertilizer? What is the NPK ratio in this soil ? And most important what is the PH of the soil in that bag ?
and do you monitor your PH ?

[szaqal007]

Soil: Canna Terra Professional Plus
Dry matter >35%
Organic matter >85%
EC 1,2 mS/cm
pH (water) zone 6,0
Organic fertilizer NPK 7-7-10 2,5kg/m3
Mineral fertilizer NPK 12-14-24 1,25kg/m3

anybody have a clue?

Your PH is to low (6.5 - 6.8) and the soil is to hot, they may or may not survive, looks more like not, sorry. Loose the nute added soil, this is very bad for young plants, and with the time release N, it doesn't get better. In my experience with autos, they are more sensitive to ferts and PH than photos, and you have little time to fix an auto, the clock is running.

If all green has disassociated from every single leaf, I'd say she's resting in a better place. Hope you have some more seeds. Live and learn

[szaqal007]

Any idea how to lower the temp. of soil?

[quietlybinary]

The temperature or the ph? The soil temperature will be the same as the tent temperature. Ventilation and light distance are factors to consider.

Change your soil.
