"the claw" and full droopiness

So I have uploaded some photos of the issue, and as you can see it doesn't look good.

First off, here is a list of nutes and environmental factors.

- Fox farm grow big 6-4-4 1tsp p/gal. every other watering
- potting soil with mulch/perlite
- 2 1/2 months under two t 12 flouro's and a t5
- 1 1/2 weeks under 1000w HPS aircooled tube style w/wing hood 18/6 light cycle
- Inline fans 1 for the light, 1 for intake
- 12" box fan on high
- evaporative humidifier

These plants have been vegging now for about 2 1/2 -3 months and are only 10" - 16" tall.
I have done a good amount of pinching and bending in the last month, I think that the t12's may have stunted their growth.
About a week ago I noticed some drooping, gave em a drink and they perked right up.
the next day they were droopy again so I wondered if maybe I had over watered. In the morning to my dismay the new growth was pointed at the ground and I thought they were gone. I then watered until it ran out the bottom (not a full flush) and they came back, before drooping again six hours later.

So here's where it gets interesting.
I had a couple of people say that they may be rootbound so I pulled one out of the container and found no problem. There are roots but not rootbound.

So I checked the ph which was a little high 7.0-7.2
And the nutes were low

I decided to flush them in hopes of balancing the ph and getting rid of any salt build up.
At the end of the flush I gave them a dose of thrive alive 1-1-1.

It has been about two days and the photos are what they currently look like.

Top growth is very light green and curled under ("the claw")
Lower growth is curled under but darker and with a few faded spots on one leaf.
all top and some lower leaves have ridges between the veins that stand way out
air circulation is good
soil temp is 65-72f
air temp is 65-78f
humidity is a little low
light is about 20" from growth tips

some of the new clones I put in the garden are showing signs of the claw and are bright green.

all are different strains
Old and young.

Any and all Ideas are helpful.
Thanks in advance.

You're not using one of these, are you? http://boards.cannabis.com/plant-pro...-anything.html

Not sure about your watering method and schedule, but just wanted to say it, that you should always water them until you get a little run-off from the bottom. Then wait until they are almost dry again. I check the weight of the pots.

How are you checking your ph? What is the ph of the water going in, and coming out? I see you said 7.0-7.2, but if you are using color coded strips for the run-off, the tint of the run-off may skew your results.

Hopefully some of the 'doctors' here with more experience can help you more. Good luck :thumbsup:

I in fact built this tent using white pvc as described in the link and it is covered with white visqueen plastic. I have had the plants in there for about 2- 2 1/2 weeks now and didn't notice any problems until after the second week. This is a bummer. It started to happen after the addition of thee 1000w which may have made the temp rise, releasing some chemicals. I hope it's not this.
Thanks though, That is the best answer I've gotten yet. any other ideas???
