is this even a problem? i can't help but worry

[explosive82]

so basically my plants about a little less than a week into flower and i start seeing the leaves look like this http://imgur.com/a/Iduv2 i made a album on imgur of it if that doesn't work i can upload the pics here the wavy leaves just confuse the hell out of me and i can't figure out what is wrong i'm using a 1000w hps and this http://www.gavita-holland.com/index.php/products/gavita-power-line-high-performance-lighting/item/gavita-pro-1000-de.html to grow under the light is pretty far away from the plants as i've heard this light is incredibly powerful any help is much appreciated!

Shes needs some calmag. Mostly mag deficiency seems like. Go get some epsom salt or calmag. Then she will be right as rain.

Also, always check your run off. Lockout can cause a lot of issues.

I think I know what is wrong.

- 0verwatered. Leaves are not flattening and lifting. Too heavy.

- They seem over fed, and in nute lock, a bit. That green seems too dark.

- I notice some light stress, minor. That is the light edges on the leaves.

- I don't see a Cal/Mag problem.


That shows up as spots.

So, to me it looks like my basic problem....pushing too hard.

I have had mag issues with deforming leave with lighter edges. Do a flush with calmag. It wont hurt and bet it will help.

 

[Doer]

Nope, it never hurts. I Spray and supplement Cal/Mag from the beginning. But, the light edges are not the problem here, I don't think.

Cal/Mag lack will destroy leaves.....then it is an easily fixed problem.

But, you know that stress based, over feeding, lock out will show all the deficiencies eventually.

Totally agree with that. I have probes in the reservoirs. And I know if I got a good root ball and don't over water, they can't be over fed. Yep.

If there is too much feed, they just take the water and the concentration goes up. Too little food, they draw down the concentration.

So, when a 400 res goes to 250 in couple of days, those are hungry gals.

But, when I see them take 600 and turn that into 750ppm, well... the are just drinking and don't need that much food.

The leaves look dehydrated not lush like they should do
both the new shoot growth and the older fan leaves have this dehydrated problem
also some yellowing , you may have more than one problem
i doubt it is a nutrient deficiency the leaves look a good colour
and its unlikely a macro nutrient deficiency could cause so much damage this quickly in veg
they can grow in my back garden in dirt without showing deficiencies until mid flower
i have seen similar damage to plants when they have suffered heat damage and or a lack of air exchange from a decent extractor
as you are using a 1000w light if you do not take care of this correctly you will cook up all the air around the plant which will burn the plant

it is also possible that the yellowing could be caused by over watering as doer pointed out

what kind of extraction are you running to bring new air around the plant ?
what are the temps, how often are you watering
you may find the plant needs to drink much under the 1000w to try to keep itself cool
if you try to water it too much in-turn you can cause other issues with the soil and roots

peace

Yeah. Hard to say. Could be under watered also.
