Necrosis & red stems - Signs of potassium deficiency?

[Hazy]

Billy i was having the same kind of problem early on in the grow, not as bad as in your last grow. i put it down to under feeding and uped the feed, at this stage mine were on 4ml Fish Mix.So i think you could up the bloom another 1ml, just as Agito said. Hazy

Yeah, think I'm being a little too timid with feeding, I was the same on my last grow :] The Big Bud solution I just fed her ought to give a big boost to P and K, seeing as the NPK ratio is 0 - 17 - 38. Should get some nice fat buds by the end of it!
