What's wrong with my aeroponic seedlings? Wilted leaves.

My log so far for these White Widow seeds...

4/28/09 Soaked seeds for 24 hours.

4/29/09 Put seeds in paper towels.

4/30/09 Seeds Germinated and placed in rockwool.

5/03/09 All seedlings sprouted and are put under a light.

5/06/09 Seedlings taken out of rockwool/hydroton and put in an aeroponic system with 250ppm tap water. Roots damaged significantly on two. Massive PH problems. PPH through the roof due to the amount of PH down and up added.

5/07/09 PH stabilized. PPM 550. Seedlings appear bent, as they did yesterday, and they do not seem to be growing. Stems purple. No spots or drooping of leaves.

5/07/09 RO water put in. Tubs scrubbed out. Salt had built up on everything. PPM 10. PH adjusted with down only. Temp 71f. Added 35% H202 at seedling rate (2 drops per liter).

5/10/09 Res temps and room temps 77F. Pump is creating heat.

5/11/09 Lots of little roots started popping out of the main root. Good news!

5/12/09 Aero seedlings have root growth, but have lighter green and droopy leaves. Getting a pump timer in 2 days to avoid overheating. Res temp 72F PH 5.8 PPM 30

The first set of pictures was taken on the 9th. The second set (including the root shot) was taken today, the 12th. On the 9th, there were no small shoots of roots off the main root. All seedlings are around the same stage in root growth.

First set

Are they still just recovering from shock? Will they recover?

they are fine one of them looks over wattered but seriously your fine.

That's great to hear.

Hope they hold out for another two days until I get my pump timer.

The little seedling leaves are turning yellow and will probably go within the next few days. This isn't normal, is it? Don't they usually stay until the leaves get a bit bigger?

Roots are still growing, but the leaves are the same and still curled like that.

i know this is an old thread, but for anyone who sees it NEVER USE BOTH PH UP AND DOWN IN THE SAME SOLUTION. They're corrosive when mixed, think vinegar + baking soda.....
