    HELP! Yellowing leaves and slow/stunted growth

    I planted a blueberry fem from seedsman and a runtz bagseed on April 5th at the age they are now compared to another plant that I have going they seem to have stunted growth. I started to notice yellowing fan leaves on the blueberry plant so today I tested the runoff and if I’ve done it properly I had a ph of 6.8 and Ppm at 883. I am using fox farm soil as well as the trio. I started feeding on 5/18 with 5ml grow big and 28ml big bloom which is about half strength. Am I just seeing nitrogen deficiency due to a late feeding ? And as far as the growth could it just be the strains ? It just seems odd that 1 plant is doing well better than the other 2.

    I grow in water, but to me it looks like you need cal mag added.

      Could be an early stage of nitrogen deficiency.
      Actually pretty hard to tell. If you never add cal-mag I would suggest starting add some in your water feeding next time.
      if you just fed it with nitrogen - it should not progress any further but if it does - then you can rule out nitrogen deficiency of course.
      But the plant are really dark green - I don’t think it’s a N deficiency.
      What size is the pot. ? - did you look up a potassium deficiency?
      Just because people are over 50 doesn’t mean they know everything.
      You can teach a old dog new tricks - But it will still think the old ways are the “best” lol


        Is that a 2 part feed ? I don't know about adding bloom to a vegging plant that's not in bloom? I don't add bloom but maybe couple times during the real bloom faze. Excuse me if this is what the manufacture states to do as I am unfamiliar with certain brands. I have heard of this brand it's very popular, just never used it.
