PLEASE HELP! WHAT'S WRONG WITH MY PLANTS??!!

[Tommyv123 8]

 

I was wondering if somebody can tell me what's wrong with my plants, I am on week 10 super lemon haze auto GHS strain. Been feeding advanced nutrients under 2 x 600 watt, 8 x 12L fabric pots and one 15L autopot (just trying it out) Soil.

Past few weeks they have been getting Bloom A and B 1.5ml per litre and last week switched from Big bud to Overdrive 1.5ml per litre aswell.

 

So they're on:

Cal-Mag 2.5ml per litre
B-52 1.5ml per litre
Bloom A n B 1.5ml per litre
Overdrive 1.5ml per litre

 

3 fans plus extractor fan so plenty of airflow.

16/8 light cycle
55% humidity
30 degrees Celsius day temps

The leaves at the top have turned yellow and crispy but the buds look and smell absolutely fine.

 

I just want to know why leaves have turned yellow and crispy?
Will the buds be fine after harvest?
How do I avoid/fix this issue?

 

Any help would be much appreciated, thanks in advance.

looks like your temperatures are way too high for this time of the year,the leafs look bleached,lot of heat stress,how far are your lights?

Too hot and massively over fed and why a 16/8 light cycle

 

What lights are they under and in what space and what size fans

are you using hydro nutes in soil? and autopot? your roots are probably saturated and standing in water i would imagine

Hello Joba, I'm using what Advanced nutrients recommend on the nutrient calculator on their website and yes it's in soil. 8 x 12L smart pots and 1 x 15L Autopot.

if you messured EC of your feed I reckon is 2.4-2.8

 

way too high

Hi 2 x 600 watt lights 2metre x 1.2m grow tent. 2 tower fans and 1 fan hung at light level, all oscillating. 16/8 light schedule because it is commonly recommended and lights are about 2 feet above plants. Thanks

if you go by these calculators and adding boosters and in soil your EC is way too high

 

if i mix standart A/B and add boosters by the label my EC is around 2.4 ,hence you need a EC truncheon to know

Ok so what should I be using ml per litre?

 

0.5ml per litre?

[joba 2,977]

if I was you I would use nothing just plain water

 

on the next one you go soil or hydro and choose nutes accordingly

if hydro you need a EC meter and pH meter,don't follow the labels and all those boosters

As above mate ^^^   I think the damage is done and too far gone for a full recovery sadly,  plain water and nurse them over the finish line.

Alright will do, why do the buds seem fine though? What will it be like to smoke?

If your on week 10 then your 1 week over the breeders estimated grow time.

 

have you checked trichs and stuff how far off harvesting do you think you are.

 

 

[Owderb 28,670]

What size extraction and what intake intake do you have

 

Take no notice of Advanced Nutrients. They talk bollocks
