What causes this? (pics)

Temp: 80
soil Ph: 6.9-7.0
Soil: (according to my soil meter) moist - not too wet, not too dry
Light - 400w HPS
Nutes - Was overfertilized 6 weeks ago. Emergency flush and transplanted into new soil w/o any ferts or nutes. Gave it some tiger bloom two weeks ago at 25% strength.

The leaves have always looked like this even before I overfertilized two months ago. I thought they looked like this because of lack of nutes in which I accidently overfertilized So I had to do an emergency flush and transplant. She recovered quickly but the leaves still remained curled. I am beginning to think it might be a disease.
She is in day 10 of 12/12. Her little buds look healthy but yellow in color. Her fan leaves are not burnt or brown just curled under like an upside down taco.

what soil you using. dam i love a mystery lol.the postman.

it looks like a nitrogen or phosphat deficiency as you say . have a look in hear to see if anything looks similar.the postman.

As far a soil goes, I am using supersoil from walmart (without fertilizer/nute additives. It was the only potting soil they carry that does'nt have added fertilizers or nutes. In the beginning, I thought it was a deficiency so I gave it a good dose of nutes (30-10-10) and within two days her leaves were yellowing and burning so I gave her an emergency flush and transplant. So I don't think it's a nitrogen deficiency.

have you given it nutes since as if its first dose was an over dose .the plant would have locked out the nutes so it may need a small dose building up to the stated dose. plants get nute lock out when they get stressed so try flushing and giving them a small dose straight after the dose. the postman.

Yup, two weeks ago. It started turning yellow afterwards. I posted that problem here and the replies I got were that the yellowing was caused from overfert! It wasn't even full strength but 25%. I flushed it with a couple gallons of h20 an the yellowing stopped but the leaves still look like an upsidedown taco. I'm afraid to give it any nutes unless I'm absolutely sure it needs em.

could be calcium deficiency.. when this happens your leaves turn brown on the ends or just cripple slowly but still live..

--to fix this problem get some hydrated lime and add about 1 tsp per gallon of water you use..

could be magnesium deficiency... to fix this add about one tsp of epsom salt per gallon of water you use..

make sure stuff is disolved, use hot water..

also, make sure water is right PH.. I Reccamend distilled water, works the best!
