If you are in soil ph is out of range. Try to water with 6.5 6.7. Test run off ph and ppm. And try to spray little epsom I have one plant do twist when want mag. But she also make taco on leaves. Is this nutes sensi a+b is ph perfect series for coco? What is your medium?

I've had plants do that when the humidity got high...

I wouldnt add epsom salts, or anything. My personal opinion. They look darn good, its not a major issue at all. I would test your runoff like suggested and find out what its ph and ppm is. If your using soil then target 6.4 to 6.6 ph is what i shoot for. I use dolomite lime with cal mag to assist in keeping the ph stable. Did you flush in veg before you put them in 12/12? What is the grow medium you are using? ?

I never use sensi ph perfect but have friend who use this line for coco and he said to me nutes make solution exactly 5.8 which is perfect for coco but not good in my options in soil. Calibrate your ph meter. Check ph again buy ph up or liquid silicon and try to up ph to 6.5. If doesn't work change nutes.
