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

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.

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.

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

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

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