Deepened Ridges in Leaves

It looks like perhaps I added too much Superthrive?

please look at photos in my journal in my sig

Please help! I'll answer any other question not answered in the journal

Seeds were planted 9/07/08 making the plants 34 days

I think its probably due to salt build up so I did a preliminary flush since I do not own a PPM meter and never had to last grow

I hope it isn't temperature stress because I'm have a hard time keeping everything cool in the room its probably around 80-90F in their (26-32C) [I'm actively trying to convert myself over to the Metric system :P]

I have not seen any improvement since the flush so I drained about 4 liters of water and replaced it with water with no nutrients

So the nutrient solution should be at about 0.65% strength rough estimate

from the original 80% solution

I am starting to wonder if I should stick it out a few more days to see improvements or whether I should switch it to pure water for a few days and wait till they stabilize

Ya have to be very careful with the SuperThrive... That stuff is REALLY strong.
No more than 2 drops per gallon of water, and I wouldn't even give that much.

Seems like it got worse since the re-nutrient-ing

So in addition to swapping 4 liters with tap water, I added another 2 liters to dilute it further in hopes of the lockout to reverse?

the pH is at 5.5-5.7

Stinky suggests that the crumpling is genetic

I took additional pictures, can this be a nutrient salt buildup?

my last plant, I had the pH at 5.5 steady and she was fine for nutrient buildup, had her own problems, but not these deepened ridges.

but this plant is around 5.5 and it is crumpling in a way that looks similar to my fellow patients outdoor plant in one corner of the yard

Also I'd like to point out that the bottom leaves are not crumpled yet the top ones are

I've adjusted my pH up to around 5.8 to see if it helps.

Please tell me if I'm wrong :)
