very similar to what I get monster cropping (cloning from plants 2 weeks into flowering) usually mine are only one blade and most curl alot tighter

I had the same problem, mine was pH problems and nutrients becoming "unavailable"
Turns out my pH dropped so low for so long that it had a molybdenum deficiency

Agreed with vestrim. Looks like your ph is off. Too low most likely. Have you tested the ph of your run off?
