She's dying, slowly. Leaves yellow-browning from bottom to top

[weedizard]

Hello. I have some problems... she's dying from bottom up.

Light: one CFL 45W
Soil: sunshine mix #6(a mix of peat, pre-made fertilizers, a little dolomite lime, and I added perlite and humus)
Nutes: Flora Nova Grow. haven't add them in some time, and my last watering(like monday) I have flushed it. The pot has 900ml, i passed through 2700ml of tap water
Ventilation: got a ventilator, but the closet stays closed sometimes.
Temperature: ambient, varying between 20 celsius and 32 celsius
pH: i watered today, the nute's solution(300ml with 0.75ml/gallon of FloraNovaGrow) had something like 6.2 ph, run off was 6.6.

What's the problem?

Also, the tips started browning/yellowing and it takes the rest of the leaf... on the top of the leaf, sometimes there's a little discolouring. And, it seems like someone put some silver powder on top of it!! it shines

 

[Po boy]

you didn't mention how old the plant is. it looks like stress from being too wet for to long. GL

 

[Bugeye]

Looks like it was over-fertilized to me. Do you know your ppm on that Flora Nova mix you used? What do you know about the fertilizer in the soil you started with?

 

[AimAim]

Looks like classic nute burn to me as well, but you didn't say when or how much you fed the last time.

Your new growth looks OK though, that is a good sign.

Why did you flush it?

 

[weedizard]

@AimAim I flushed because I tought the problem might have been nutes.
The plant is stunned, haven't grow in times

Last time I fed was 2 weeks, like thursday. (day 2

@Bugeye it says, for my dosage after the flush, like 400 ppm

@Po boy it's been dry like a desert since yesterday. Been waiting the pH meter to be delivered. Plant is 8 weeks old!

This issue has been going on since the beggining of the plant! All new growth healthy, old ones dying.

Read this before you do anything else:

How old it that plant?

It obviously does not like the soil environment, unless perhaps you burned it with lamps several days ago. It looks big enough to transplant, I'd carefully replant to a larger pot with a decent (at least different) soil. Not saying your soil is bad, but she ain't liking it so far. No nutes at all, just get a general potting mix with no added slow release fertilizer.

Just my opinion but that's what I would do.

 

[Ilovebush]

As mentioned...looks too wet, keep pH between 6.3-6.5, and possible nute burn.

 

[weedizard]

@AimAim Transplanting it to another soil may be hard... she's still in this one, how will I remove it?

@Ilovebush i'll feed her more tap water once she gets all dried up again! The thing is she was dry for 2 days... had to water her again

 

[Karma0413]

Nute burn...

The damage is done. Leave her be and let her recover. Do not transplant, trust me... I made this mistake. If you already flushed then let her dry out and then water without mutes x2. Then reintroduce again at 25% strength.

that plant is 8 weeks old? i know i get slammed for saying this but i dont fed till my plant tells me to. no nute in dirt or nothing. a seed has all the nute it needs to last for a long time. mine is 6wks old and i have put nothing but water on them and no nute in dirt.

sweet.

i never fertilize till the plant demands it.

what soil you using thats got no nutes in it?

soilless mix or actual "dirt"?


EDIT: also, dont keep your guitar there. the humidity from the plant, and heat from the lights will ruin the tone, and over time will degrade the glue in the basswood supports around the body and it will start buzzing.
cover that guitar and keep it away from your grow.

Damn you guys stay in veg for a long time. 6 wks 8 wks? I guess if you only have one plant it makes since to get it big, but you have to have lots of light for a big girl. One 45w cfl is not enough in my opinion. That will also have an effect on how much nutes it can use. A plant can only process the amount of nutes it has light energy to process. I would agree its a nutrient burn, but I would give more light - same nutes.

Ck1 I run a 400watt hps. and i scog makes for good yield. most people i know get close to as many grams as the watt of their light. 4oowatt hps means close to 400 grams with scog. so just saying everybody has their own way. two different growers with the same strain wont have same results.

LOL its ok a have her in a box i just took her out so i could take pic. i didnt want to shut off the light and wait for to cool before turner it back on for just a pic. the box she is in is on the stage with everything. i like to open the doors on the box when we play.

Updating! I tested my soil pH by the method someone posted here in the early responses(really nice link btw).

I took 3 tablespoons, added some water, and the pH meter said 6.5!

So my pH is super fine... which brings us to the question : is this a nute burn, or moisture stress?

p.s. she's stunned also

PH is usually not the problem, cannabis can grow in acid or alkaline soil, and only if the PH is way out will you have a pronblem. you got overfeeding and overwatering issues.

if you pull her out of that pot, the dirt at the bottom is gonna be a sloppy mess.

plus, if that pot doesnt have enough drainage thats another problem that can cause these symptoms

move her to a larger pot (with lotsa drainage) and plenty of fresh soil below and around the root mass, dont water till the top starts to droop, and dont feed for a long time.

if the soil smells sour or you see slime, wash the rootball gently in warm (not hot or cold) water and put her in all fresh soil then water her in good and then water way less.

Ok thanks! I'll give her tap water, way less, and let's see what happens

 

[*BUDS]

This is heat issue, stunting the plant. I think it gets hotter than 32 deg even at that temp you will almost kill it. It has major heat stress symptoms, canoeing stunting yellowing and no energy. Get temps under27 at all times.
