Potassium in hydroponics · Hydroponics Daily

  Welcome back to Hydroponics Daily. Today's subject is potassium and the chemical
• 0:05
  symbol for potassium is K, confusingly, and it's K because of the German word
• 0:11
  for potassium begins with a K.
• 0:13
  It's important for enzyme activity and enzymes are important to all life on earth.
• 0:18
  It's important for cell turga, so keeping cells inflated with liquid inside,
• 0:24
  pushing against the cell wall, making sure the plants don't wilt and then
• 0:28
  also stomata control control controlling whether
• 0:31
  the stomata the pores in the leaves are open or closed that's
• 0:34
  very important and potassium has
• 0:37
  a crucial role in signaling for that that process
• 0:40
  deficiencies of
• 0:43
  potassium are rare probably one of the rarest
• 0:46
  in hydroponics and it's rare because
• 0:49
  all feeds contain ample amounts of potassium and
• 0:53
  really you'll you'll far more
• 0:56
  commonly see symptoms of of of toxicity from
• 0:59
  too much potassium than you will from from too little and that's
• 1:02
  because all the additives that when you're trying
• 1:05
  to get nitrogen and other compounds potassium in they're often.
• 1:07
  Linked to potassium you want to avoid sodium
• 1:10
  so people put potassium salts in there and and
• 1:14
  so you've any base feed has got plenty of potassium
• 1:17
  then people go on with pk products and that adds more potassium
• 1:21
  i've never been a big fan of pk boosts and
• 1:23
  things like that i'd rather go on with an iron fertilizer in
• 1:27
  flowering add some real weight to my product rather
• 1:30
  than a potassium based product and and
• 1:33
  so really you're very rarely going to see it the only time you're
• 1:36
  going to see it is when you're watering without feeding into
• 1:39
  an inert media so say you you've vastly
• 1:42
  underestimated how much fertilizer you're going to need and then
• 1:45
  you only apply it once or or once a week
• 1:48
  or once a fortnight and you're going on with water and all that
• 1:51
  potassium is being washed out and you've got lots of runoff then
• 1:54
  you might see symptoms of potassium deficiency but if
• 1:57
  you're seeing that you'll be seeing symptoms of nitrogen deficiency first the
• 2:00
  classic exam symptom is yellowing at the leaf tip and at the margin the edge
• 2:06
  it's called the margin so potassium deficiency very rare there's loads of potassium
• 2:10
  in in gold leaf or in the uk liquid gold and and i wouldn't really worry about
• 2:16
  it it wouldn't keep me up at night. Got an interesting story.
• 2:20
  When I was doing my undergraduate degree in plant science, there was a fellow
• 2:24
  student who wasn't that clever, and he got confused between potassium and phosphorus
• 2:29
  because he just saw, oh, I'm doing my dissertation on,
• 2:32
  on potassium deficiency and he just went
• 2:35
  to the cupboard and got all the chemicals with p
• 2:38
  in them thinking that that was potassium i mean how he
• 2:41
  got through a level even gcse you know high school
• 2:44
  chemistry i'll never know but yeah he he
• 2:47
  ended up doing his his dissertation his thesis on on phosphorus in the end because
• 2:52
  that's what he'd been doing he got mixed up between the two don't get mixed
• 2:55
  up between the two remember potassium is with a k and it's important for keeping
• 3:00
  your plants turgid and full of vigor and keeping those stomata open when you
• 3:05
  want them open and closed when you want them closed.
• 3:07
  Okay, any questions about potassium in the link below?
• 3:11
  And what else we say about potassium? Yeah, that's probably about it really. Okay.
