Plant problem. Need help

[Vpark]

Hey Sunshine

Just to recap I'm growing in pro mix medium not soil
I didn't mix it with anything at all
I haven't used any compost.
I water once a week now.

? just a dumb question V how large are your pots. as sunshine quotes its all in the ph needs to be 6.0 to 6.5 and time that is your best mark

 

[Vpark]

5gallon

 

[Alphatoy]

No brown tips
Canopy temp is at 77-81
So I don't think it's heat stress
I have a fan directed at the plant
And I give the pot a half turn every few days

I try to Keep my tent Temperature at 74 from what I have read about cannabis they like 72 the best temp for growing.

Got you. Make sure you ph your liquids after nutes are added and consistently check run off and adjust as necessary.
This isn't the easiest path you've chosen but you'll learn alot about growing along the way.
Hope your plants perk up! Keep us posted ?

Hi guys

Plant keeps growing.
Watering now once a week
pH level is perfect now
But I'm still getting the brown and yellow leaves.
Same as in the previously posted pictures picture.
Any suggestions?

The plant is probably 2 feet tall now
As of today I started the flower cycle
I'm afraid if I keep it in veg any longer
It will outgrown the tent hight in flower.

?did you top it yet Vpark topping it will shorten the height problem glad about ph is it the same older leaves or is it also the new leaves if it is the older leaves well most of the time they can not revert back to new leaves look they will stay looking like that until brown and death

 

[Vpark]

So it's still the older leaves
as some dye others begin the process
If I trim the dyeing leaves
I start to see others get effected. Within a day or two
And it's all over again.

[Vpark]

5 liters

well try letting them die and fall off their self that way you might not effect the others I have never heard of this problem sunshine will be on here in a few hours maybe he will have a better answer to this problem.

Water to harsh

Hey @Vpark sorry to hear your still having problems.
The probable causes of the nutrient uptake issue are:

• Hydration/watering problem ie over/under/irregular
• Pythium/root rot
• Ph problem

Something's causing the lockout and it's going to be a process of elimination to determine the exact cause but I wouldn't be suprised if it was root rot. If that were the case then using diluted hydrogen peroxide may be an option to restore root health. Good luck and keep us posted ?

 

[Vpark]

Any suggestions on the procentage to dilute hydrogen peroxide
