I have yellow tips (only slightly)on my new growth and some of the old leaves at the bottom have gone yellow I’m confused to weather I have nitrogen deficiency or nitrogen toxicity can anybody help ? Thanks
Pictures tell more than words buddy.
How old is the plant? bottom leaves yellowing and dying is normal and no preoblems. The yellow tips on your new growth could be a few things.
First always check you PH its the first go to with anything. After that i only ever get problems with my tips if its not enough Nitrogen or Calcium
I am using bio bizz all mix with the bio bizz nutes , the plant is around 6 weeks from germ apparently the bio bizz buffers PH so I haven’t been doing it thanks for the reply’s 👍🏽
Another nutrient is causing nute burn and at the same time may even be responsible for a N lockout, but it may also be just lack of N and excess of other nutes, without pics its hard.
