Hey Rasta
Im a newbe so cant tell you whats wrong with your grow but I know those who can are going to want some more info.
I use this when asking questions. Hope it helps.
Just copy paste and answer questions Good luck and get well soon.
What STRAIN are you growing?
What was the establishing technique?
What is the age of your plants?
What PHASE are the plants in?
What Technique are you using?
What substrate/medium are you using?
What is the Nutrient temperature?
What Nutrient's are you using?
What is the TDS/EC/PPM you are using?
What is the pH of the "Tank"?
Are you sure your calibration is correct on your equiptment?
When was your last watering?
When was your last feeding change? (ie. grow-bloom-micro-added)
What size bulb are you using?
What is the distance to the canopy?
What is your RH Factor?
What is the canopy temperature?
What is the Day/Night Temp? (Include flucutaion range)
What is the current Air Flow? (cfm etc.)
Is the fan blowing directly at plants?
Is your water HARD or SOFT?
Has plant been recently pruned, cloned, toped?
Have any pest chemicals been used? If so, What annd when.
Are plant's infected with pest's
I didnt come up with list of questions another member did im sorry I cant give him or her the credit they deserve. But thanks

What STRAIN are you growing? they are blueberry from dutch passion and white skunk from white label
What was the establishing technique? ummm.....i dunno i bent them to keep them short.
What is the age of your plants? 12 days into flowering 69 days old from seed
What PHASE are the plants in? flowering
What Technique are you using?again? lol
What substrate/medium are you using? pro mix xp with no ammendments
What is the Nutrient temperature? the guano tea is brewed at room temp b4 given to them
What Nutrient's are you using? everything in burnones guano tea mix xcept the maxicrop
What is the TDS/EC/PPM you are using? no clue i dont have a tds tester
What is the pH of the "Tank"?lol i dont have a ph meter or testers
Are you sure your calibration is correct on your equiptment?no eqipment to calibrate
When was your last watering?day 66 from seed day 9 flowering
When was your last feeding change? (ie. grow-bloom-micro-added) the last watering was there first flowering mix
What size bulb are you using?150w hps
What is the distance to the canopy?5 inches
What is your RH Factor?37%
What is the canopy temperature?72 night time up to 87 during the day sometimes
What is the Day/Night Temp? (Include flucutaion range)^^^^didint see this question b4 i wrote that
What is the current Air Flow? (cfm etc.) i just have an oscillating fan on them and another clip fan
Is the fan blowing directly at plants? yep
Is your water HARD or SOFT? no clue
Has plant been recently pruned, cloned, toped? nope
Have any pest chemicals been used? If so, What annd when. nope
Are plant's infected with pest's? nope

I was thinking it was transpiration issues. Leaves can fold up in order to transpire less in low humidity/high temp. environments. If you are not seeing any type of nute burn or other leaf distortions, I would say it has to do with that. Humidity of around 50% to 60% is alright at this stage of flowering in my opinion. Plant is busy at this point. Lowering the humidity towards the end of flowering, as the buds become denser, will lessen your chances of complications from mold/bud rot. Just my opinion so take it with a grain of salt. Read up on transpiration of plants, Ed Rosenthal is where this following came from. I find that low humidity causes stress on plants. I recommend 50-60% humidity until the final 2 weeks of flowering. At this point, the humidity should be lowered as much as possible to encourage the plant to seal and protect itself with additional resin. (I am able to get the humidity to go as low as 31%) I have been able to frost things up considerably this way. The higher humidity levels prior to final ripening reduce salt levels within the plant tissue and encourage healthy, more lush growth.
^^My thoughts as well...low RH combined with high temps and a fan blowing directly on them can easily do that.

well my asshole friend germinator kinda gave me a good idea earlier he told me to folier feed them water with 1tsp/liter of epsome salt and lift my light so i now have my light 9 inches from the canopy and i folier fed them with the mixture and....the little basterd is right.... the curling is backing up slightly but visiblyhaha thanx buddy but ya now im at 79degrees and 67% RH and i think im going to be ok

In my experience, the ONLY time I have seen this type of behavior where the leaves would taco, or fold in half towards the light.....
HEAT STRESS/SUPER LOW HUMIDITY.
The leaves are trying to transpire meaning you either have a fan blowing directly on them, causing them to dry out; or you have a heat issue and they are drying out from the temps.
You'll probably quickly identify which one of the above it is. Hope it helps!

Bingo!!!! No question.
High Rasta,
The symptoms showing are from overfeeding, nothing else. The leaves are darkgreen and curling up.
If you have a magnesium defficiency it could have been too wet, too cold or too low pH-level in the soil. But could also be an overdosage of kalium (K) or calcium (Ca) because of high levels of calcium in your water. Or even a calcium fixating soil.
Peace
