Green Crack Clone Sitting - N def, light burn, both?

Hi, I've been tasked with clone sitting an established Green Crack clone. When I got it, I thought it looked hungry, with pale leaf centers, and some spindily new growth. Before I got the plant, it hadn't been under any lights for about two weeks, but it looked fairly healthy. Since it has been in my care, the leaves have yellowed somewhat. Some of the leaves started to curl slightly upwards, and there are a few leaves with some necrosis.

I'm a hydo guy, and this is a soil plant, so I'm a little hesitant to start changing things too much. I tried giving the plants a 600 ppm 6.0 pH watering about a week back from my hydro nutes. I'm worried this might be the source of the problem, but I'm not sure.

For the last two weeks, it's been about 12" below a 250 watt HPS. I tried raising the light to about 18".

What do you think? I'm going to get my ass kicked...

i've had plants 4" from a 250 with no light burn so I doubt it's that. Some pics might help...

Okay, I think the image issue might be due to me setting the album to private. Let's try again...

Your going a little low with your p/h for soil and looks like it's causing a Nuet. Lockout. Soil likes a p/h of around 7.0 if I'm not mistaken, been a while since I've grown in soil, but 6.0is a hydro p/h.you shouldn't raise your ppm until your p/h is in check.when your p/h falls into the right range the nuets. in the soil will become available.if you feed to much and the p/h isn't in the right range it's just going to build up in the soil and you'll get nuet.burn.
image 3looks like a mg. Def.yellow leaves with green veins, again 6.0will cause mg. To be locked out.

I did some reading on soil growing, and I tested the runoff, which was at 5.2 pH. I don't know what the owner was feeding this momma. I flushed the plant with a higher pH until the runoff read 6.2 pH. This was about 3 days ago, and I've already noticed the leaves turning green(er) again. Nitrogen lockout due to low pH.

Now I've got the problem of the plant being rootbound. Should I wait a while longer before doing any root trimming and replanting? I'm just worried that the change in pH might have shocked the plant a little. As it goes, I'm planning on root pruning and transplanting as soon as the soil drys out from the flush.

I'll post pictures soon. Thanks!

let it recuperate a bit first.
Since that plant's in soil, you don't want to use your hydro nutes, cause the soil already has the micros. red stems = low pH, because P is deficient in acid soils. N does not get locked out by low pH. Though microbial activity will slow the mineralization of organic matter.
Lack of N would show on bottom leaves first.

How long should I wait? Will the stems turn green again?

I need to wait at least until the soil drys, that should still be at least 3 or 4 days, if not a week. It's not really creating any new growth, and the water uptake is slow, but the younger growth seems to be looking much better, while the older leaves look a little worse.

Here's some updated pictures, some of the leaves turned yellow and fell off, but it looks like it's trying hard to come back, but it's extremely rootbound. Should I root prune it now, or wait longer?

Transplant it now and trim just a little bit of the roots away. You could also trim a little from the longer shoots.
You'd be amazed to see how fast it will start looking better. Make some clones when you have enough fresh growth and start some new mothers just in case.

Or send it to me:)

It's been a week and a half since the repot, but I still haven't seen any new growth (other than the roots). Should I be worried? She's not looking too hot.

I transplanted it about a week ago now, it's lost some more of the bigger older leaves to yellowing and falling off. I'd be more worried than I am if I hadn't have noticed fresh roots peaking out of most holes in the bottom of the bucket. I cut the bottom inch of the rootball off.

So, if there's new root growth, even though there's no new veg growth, does that mean she'll pull through?
