wierd lettuce looking buds, fault of bad npk?

i have something much the same going on at the min with my girls. i decided to just leave them. whats the worst that could happen.theres not much there to smoke anyway so why worry.your leaves look fine. also you only get 2to3 weeks in the first stages of flower to put things right and after that its all over my freind.just give them water with maybe some forceing firt.that way they will still get feed. good luck. check these out.all help will be welcome
