Anyone know what the problem is?

72* is within the parameters of acceptable temperature range.
According to Greg Green
"You should aim for 75*F, but slightly warmer temps do help plants to grow a bit more quickly....
You do not want to go above 85*F, if you do you will only heat stress your plants and stunt growth....
During the 12 hours of darkness during Flower Phase the heat from lights is gone and temps can go as low as 55*F
Try not to allow temps to drop much lower than 55*....
....Below 30*F and you can expect serious plant damage...."

i believe 72 is way to low for veg. pretty sure thats a fact. and 55 degrees in any stage of indoor growing is super bad practice.

that plant is hungry . get a real nutrient. some thing like a 10/10/10 Is perfect for veg and keep ph in check you will be doing great. the temps are normal. 72f is not cold. your getting some bad advice above. you can take the temps to 60f most strains with out any problems. my clone room is about 45 f they stay in there for 3 weeks very happy and healthy.

I'm having a hard time believing the temps your throwing out there. for this to be stated is unreal. 60 degrees, 45 degrees. I'm calling bull shit on this one.

Here's a new pic that I took just now it's gotten worse it looks like and I put more pure pH'ed water in the res. I think it may be lacking mag. What do you guys think?

i think you should just add your three part at half to 3/4 strength and PH it to 5.8, thats what i like for hydro...i think that will generate response in the plant, and 45 is ay too low that stupid. 65 is the coldest i would go..

So you think it's being under fed?

THIS INFORMATION IS INCORRECT!
By following this advise, and taking your pH to less than 5,
you actually will lock out nutes.

Obviously both of us cannot be right....
So do some checking before you accept either of our suggestions.
5.2-6.2 is the acceptable range for hydro pH.
Go check.

(and here's a few of the buds I have growing....
They're doing surprisingly well considering my pH has been kept between 5.2 and 6.2....)

How come some of the leaves on ur buds r brown and look crispy?

Not positive but it could be early signs of tmv / hmv.

oh come on!!!!

dude yo u need to get the ph under control. it is to high in hydro ! it needs to be @ 5 ish . look it up. your well over that. in hydro its a must proper ph. if you don't want to check it and get it under control might as well toss those plants into the trash. ph . will lock the plant up it will not be able to absorb nutrients at all. even if you hit them 100 times as strong as normal if the ph is to high and the plant is locked your fucked. and I do have the temps in my clone room. its hydro cloner home made 100 site. the window. has a ac unit installed just for the clones. and I just shut the vents off in the room during the winter it gets to 45 ish in there @ night. very cold. I used to do clones at 60f . but I have never seen more healthy looking plants after being in that cloner for 3 weeks with out any bull shit clone solution. my clones are 100 % green 6 inch long roots or more. they are 12 inches tall cut off there mother. I found this out by mistake , I was lazy never took out the window ac unit. any body that has one knows cold air blows right through those.

Sorry I'm a noob but what is tmv or hmv?

my serious advice. is sit down and read every thing on this website. and learn. you have chose to grow the most difficult way possible . just wait to summer when every body is on here with root rot. http://www.420magazine.com/forums/problems-pests-disease-control/81275-cannabis-plant-pest-problem-solver-pictorial.html

I know how to control the pH I'm just worried it might lacking magnesium so I hand it higher to it will absorb what it needs cuz it's turning a bright green/yellowish color..

haha ya I know it's the harders I transplanted into hydro cuz it goes the fastest but I should of left it in the coco even tho that's still hydro. I have more seeds on the way so I'll probably try at least one seed in the coco.

Tobacco or Hemp Mosaic Virus.

If you develop twisted leaves and increased chlorosis then it's what your dealing with. Note in some leaves the white areas near veins. Also top leaves look deformed somewhat.

Not saying it IS but it could be. Time will tell if nothing helps and it worsens.

Light burn.
1000w in an air cooled
had it too close and scorched the centre plants.

I know this for a fact because more than 1 plant is affected
but all the signs if damage are directly under the most central part of the lamp.

You may be 'pretty sure'
I am CERTAIN that you're wrong.

72 is about perfect - maybe a touch under.
To go as high as 80+ will shock the roots, stunt the growth.

Who's plants are you talking about???
The OP's
Or mine (with the brown and crispy fan leaves....)???

Gunna flush it out with pure pHed for a day than but higher nutes in it late tonight and see if that helps

Looks like nute burn, flush them and stop using nutes for a while.

Ya I dunno what it is yet, I'm flushing it out as we speak, the yellow tips on the first node leaves r from the stress of transplanting, but it's turn bright green on the stem of the older leaves it's weird.
