I have problems with one of my plants here are the pics .
Can someone please help me because to be sincere I don t know what to do because I really think that I miss interpreted this deficiency( I was thinking that is mg deficiency ) .
right now I flush the plant it is in week 7-8 auto white widow from low life seeds and I use advanced nutrients line .

Hi Bluedaemon

Looking at the photos, i'd normally say nitrogen and calcium def.
Have you checked your PH run off?
I think a flush followed by a light feeding might be a good idea.

I saw your other post with your nute line up

Grow Micro Bloom
Connoisseur
Voodoo
Big Bud
B-52
Overdrive
Piranha 50g
Nirvana
Sensizym
SensiCal Mg
Nitrozyme

Are you really using all of those nutes on this plant?
If so, it might be an idea to strip it back to basics until your plant is happy.

All the best
Blue

I agree with blue, cut back to basic nutrients with cal mag...verify pH.....

I also notice a bit of leaf curling at the edges...check the inter-related factors of temperature, humidity, and distance from lights to make sure everything is optimal.

There should be enough time to get her turned around, good luck!

Hi guys first of all thanks for the answers
Can you please give me a schedule for advanced nutrients per weeks with the ppm that it is best for autos. from what I read the auto strains are different and the nutrient solution have to be different that way I ask this .
also any advice its well given .
I have problems with the moisture its around 65% sometimes its dropping around 50% .the light have cool tube reflector and even if they are close i have good aeration in the grow area .
by base do you mean to give them a lite mix with only connoisseur A+B ?

also the PH run off it was 6.5-6.4 . I flush and I use Florakleen now I have to wait a light cycle and then give her food, this it will be tomorrow night

Hi guys

today I take the run off PH and it is still at 6.4 and I give her RO water plus CONNIE A+B 2 ml / liter.
I like to tel you that I find out what's wrong at my grow . look I use from the bluelab http://www.getbluelab.com/shop/Bluelab+Truncheon%AE+Nutrient+Meter.html witch iti is very good pice of equpment for a grower but on the meter I have the EC/x500 ppm scale and the CF/x700 ppm ( american scale that Advanced nutrients use on they schedule ) well like a good european I forgot to use the same scale like Advanced Nutrients and I use the different scale .
Now when I look at my grow notices I see that this strain can take up a lot of nutes because when I make the transformations well i give them ppm around 1000-1200 fervently with a peak of 1400-1450 ppm on the american scale .
So I hope from now I will do not have any trouble any more .
