Yellowing and leaves turning down can anyone help with diagnosis?

  1. My plants are in 1st week bloom and I'm noticing turned down leaves and yellowing. I think it N deficiency. Should I add a fish emulsion like FF wholly mackerel? Here are some pics 5245.jpeg 5244.jpeg 5243.jpeg 20200107_150919.jpg

  2. Drooping leaves are usually thirsty. I can't say I have any other ideas about the yellowing. If it is nitrogen, I'd be surprised to hear that it's happening in the first week of bloom.
     
  3. Also looks like possible Phosphor or Potassium deficiency with that brownish leaf on the left, at least thats how mine look after underfeeding

  4. Come to think of it, I think I like the nitrogen hypothesis. The plant is going to use that to stretch in the first weeks, and if it isn't getting it, you would expect the newer leaves to look a little lighter and lower leaves to start dying off.
    Is that what it looks like?

  5. Yes I am going to make adjustments on the next feeding. But after I feed them I check the ppm and its eating optimally there is no excess nutes and the soil is super dry. They are being fed every other day
