WTF leaves wont stop twisting please help (pics)

alright so i had a different thread a week or so ago i currently have 21 ak47 plants in veg they actually just went into flowering 3 days ago because the are already almost 3 feet out of the buckets. They were in veg about 6 weeks. So about a month ago i noticed the leaves were starting to curl and kind of fold over. So after talking with friends i thought it was a mild case of nute burn so i stopped feeding them nutes and started giving them just water for about 3-4 weeks. Then my buddy told me it could be due to my ph so i bought a ph meter and adjusted it to 6.5 and fed them with nutes about 4 days ago. the curling still has not stopped and some of the fan leaves are curling but it is mainly the new growth. THey are in FF oceans forest soil 5 gal buckets unter 1x600 watt hps til they go into my flower room temps are around 66-80. PLease help i cannon figure this out. By the way they were just fed liquid karma and grow from botanicare. those are the only nutes they had. And i did not feed them for 4 weeks and just fed them.The leaves are also all green and no yellow or brown.
sorry the pics are so bad. lol
Thanks

cant really see in those pics, but from what i can make out it doesnt look like a huge deal?

Its usually temps that cause this

take your ph down to around 5.5/5.7 try that for a while but if your plant are nice and green don't worry so much i find that leaves canoeing or twisting is normaly heat related.lower your p.h and higher your light a tad.good luck

thats nothing to worry about..those leaves will go away, and be replaced with lil white sea-urchin lookin things(pistils)
