Your plants don't look as bad as some that I've seen.
I agree with everyone to allow them to finish.
However I would have to disagree that feeding plants causes crackle and popping of your buds.
I feed the whole way through flowering using Veg nutes and some PK1314. I have lovely green healthy plants at harvest time that taste fantastic and yield very very well.
Alot of people here on RIU are still into the old way of growing, which is feed hard until you burn the shit out of your plants and then flush to remove the excess nutes.
Personally I feed them enough to keep them happy and healthy. Many people ask how to improve yields or flavour of the final bud and my advice is always simple, keep them healthy and happy and they will perform the best they can.

Agree fully. People ask me what my secret is. I'm like, no secret, I just don't piss them off on a regular basis with trial and error type of bullshit. tried and true methods work best for me. Now with hydro, your PPM numbers are gonna change consistently. The plant lives in water. So you would figure that you would need to flush during the last two weeks.
Tried that, saw a massive decrease in bud production. Those last 2 weeks are prime time. I keep the same level of nutes and don't flush. A happy plant will produce happy buds.
New, impatient, inexperienced growers are usually the ones with lame ass results from half assed setups trying to throw every nutrient at their plant to make them go "beast" mode... usually learning they just made them go "bitch" mode by doing that.
As far as "adding nutes until nute burn occurs and flush em out"... that's a bad idea. been there, done that, and I would rather correct a deficiency than a nutrient burn any day.
happy harvest.. GW
