Re: plz help, leaves edges curling under

How about some more information?

Start with this...

How many plants? What Kind?
How old are they?
Indoor or outdoor?
How big is your area if its indoors and is it well ventilated?
What medium/soil are you using?
Whats the size of the containers?
What's your lighting set up?
What's the temperature and humidity like at any given time?
What's your pH like, both medium and nutes?
What's the NPK of all your nutes?
How often are you feeding with nutes?
Any pests around?
What is your watering schedule ...

Re: plz help, leaves edges curling under

With the information at hand, it looks like over-watering.

 

[Lester Freeman]

The "claw" is usually a tell-tale nitrogen toxicity, that or overwatering, or both.

 

[VladimirPutin]

leaf tips are burnt.

by the tell of that dark green shade I'd say it's time for a flush, but if the plant was also over watered then the solution becomes complicated ??

soil looks dry enough from the 1st picture. Tell us the plant's life story and we can help you!

i really appreciate all the replies.

pot size ( 30cm wide, 25cm high)
pH (6.3-6.8)
soil: regular potting soil/coco mix.
watering : when the top half inch or inch of the soil becomes dry ( every 4 to 5 days)
the plant is a month n 18 days old.
week 2 of flowering. ( showing tiny gender with tiny pistils)

Vladimirputin the lifestory of a plant...

first 3 weeks the plant was v healthy with the leaves straight open.
n then the plant suddenly got nitrogen toxicity ( claws on almost all the leaves). without being fed.

flushed it with 2 gallon of water, the claws still appeared on atleast 2-3 outa 9 fingers.
at the same time the problem which i mentioned (leaves edges curling under, rolling themselves like a joint ) appeared n affected almost the whole plant.
from 4th week onwards
started feeding it NPK(13 : 25 : 25)
1 ml per litr + cal mag etc 1 ml/ ltr too.

the growth boosted abit after feeding that but the all the leaves still continue rolling under as the time passes.
its in flowering week 2 now
sorry if it was too long.
really hoping some1 to help me with this. coz i only have 1 plant.

3 cfls (45w each)
1 on top n 2 on sides. all about 2-3 inches away.
temperature between 20-30•c

That pot is roughly 3 gallons?

"NPK(13 : 25 : 25) 1 ml per litr + cal mag etc 1 ml/ ltr too."
It sounds like you have salts built up in your dirt from the high nutrient feedings.

A flush is required, if you have a 3 gallon pot, take 9 gallons of clean water and saturate your pot allowing all the runoff to escape to drain.

Do 1 flush in the morning, give the plant access to lots of sunlight if possible to aid in drying out the soil after the flush

3-4 days when the soil becomes dry again, continue feeding with 1/2 strength of your nutrient plan.

Good luck She could recover to still give you some bud.

Thanks Vladimirputin, I'll give it a try n see.

are these stipsules? or gender?

 

[VladimirPutin]

Too soon to tell. By week 3 of flowering should be clear what's going on.

They are slower to turn due to the rich Nitrogen reserves in the soil,
veteran growers change to "bloom" nutrients for 12/12 times.
