Funny looking bud leaves......

[calstar]

Leaves on some of the ladie's buds are curling, twisting, any thoughts on whats going on or is this sometimes typical of different strains(this is sweet tooth). thanks

They look fine. Some strains do that in flower. If it is a problem, it could be a ph or calmag problem (or both).

Maybe strain related as two other strains I have aren't showing this. Ph is closely monitored as is EC. Calmag I don't think so since I've no other symptoms except sunscauld(I think its sunscauld but see pics, lower level leaves are not affected). Is this some nute related issue? Anyone? Thanks
