Help ..yellowing

Hasnt shown much vertical growth in a while. Lockout?

Nitrogen deficiency?

Are you growing indoor, outdoor? What are you feeding? How old are the plants?

I get this on my plants too what nutes are you using? Have you checked your runoff PH? It was because my plants where hungry let me know

Plant is 45 days indoor and im using fox farm trio following FDs feeding schedule and adding calmag

Right, I have had the same thing in the past. Don't always jump to a deficiency chart! Look at the basics 1st, bad air flow will do this. It looks saturated too, are you overwatering it? Are you letting it dry out so it feels so extremely light, then giving it an extra day to use the feed in the plant? Get a moisture probe. £4.99 from hong kong. Plants will shed lower leaves at various stages in your grow. That is 100% normal. Personally, I would remove some of the unhealthy lower leaves and get more air flow there 1st. It is essential that you let the soil dry properly, so it feels unusually light weight. Don't panic, it probably has food in already, so don't feed it before trying to improve air flow. Also, make sure the pot is raised and air can get underneath the pot.


When did you feed it last and how much?

Your plant looks very healthy in general, it is nearly 7 weeks old, I always lose lower leaves at this stage. Overwatering will cause lock out, then deficiencies. I'm 100% confident if you let it dry properly every time, raise the pot (even 5mm), and get some more airflow there. I would try and have the fan lower, it doesn't need to be directly aiming at the plant. It just has to gently move the air around the root system and base of the plant, it will then go up through the leaves anyway.

Lookin good mate, if you have let her dry out properly it looks to me like the soil was just a little light on N. This happens with some strains that are Nitrogen whores. It will slowly work its way up the plant until it is ready to harvest. You look to be in the first half of flowering, so it may be a little to early to run out of nitrogen. I am not familiar with your nutrients, but I use a tiny bit of pure N added to my feed to cure this problem. The yellow leaves wont come back but it will stop the others from turning yellow. Hopefully someone else will stop by with a more specific suggestion of how to get your lady the nitrogen she needs.

As for the height, she shouldn't really be growing any taller at this point. Some autos stretch in flowering but I don't think this one will. She is just going to get wider and wider now! With Bud!! So no worries on the vertical growth. Hope this helps somehow.

Moving this to the Infirmary section bud - as noted by mallo she looks good just looks like she needed a little more nitrogen than required when she went into full on bloom and still needed some nitrogen for bud development there wasn't any to be had so it starts to come out of the lower leaves. This isn't your everyday deficiency but it's common. I'd stop using CalMag and start using Epsom Salts for bloom as well, the Magnesium is far more essential than the calcium once you're in full on bloom. It will allow your ladies to transport nutrients a little more steadily and in my experience has also helped to reduce the lower leaf eating.

Next time feed veg nutes just a little bit longer.. FD's guide is an outline and while it's a great guide the industry has changed quite a bit in the past three years.

I used to get similar deficiencies, No longer get any as I feed my plant Grow + bloom, Not grow instead of bloom.
