10 days ago the symptoms were very minor, thinking I was facing a deficiency, I started a light irrigation with a liquid fertilizer npk 4 3 6 (biobizz biogrow), and with biobizz algamic, practically an algae extract.. but as the days went by the symptoms got worse, and I found myself with the situation you can see in the photos. I think it's a nutrient lockout... what do you think? the plant is in a 200 gallon mound, the soil is composed of peat, coco, compost and native soil (clay and limestone) fertilized with an organic pellets NPK + Ca, S, Mg 6 5 13 + 10 15 2
I would like your opinion... outdoor leaf chlorosis

looks like it was humid at some point, most of your leaves look good nute wise any way you can show the whole plant get a better idea of the pattern.
Also what genetics are those ? looks like a Mazar i sharif.
a nice afghan it looks like tho.

the genetics is a Royal Kush bx 10 gen. by Emerald mountain seeds. I don't think it could be an excess of water.. it hasn't been raining for a long time and it is very hot, with maximum temperature peaks of 40 degrees (104 ° F). moreover I maintain (also for logistic problems) a rather low irrigation. concretely speaking, I usually irrigate every 2/3 days with only 6/9 liters of water. And the plant rests on a bed of almost 2 square meters, at the moment the plant with the branches covers an area of about one square meter.
...in the photos above the translucent specks that can be seen on the leaves are due to the freshly sprayed neem oil ...

You are very helpful master grower. This entire community should have some jumbo harvests coming up.

I only ask because The 17 nutes all have a very distinct pattern (top to bottom, bottom to top, and middle up or middle down.
Now that is obviously simplified but its a good start ,the more plants you have the easier it becomes to see the pattern.
Like when the plants finish just right, all the leaves except the surf leaves are green, Buds are fat and whatever color they end up as they do their best mimicking fall,pistils are turning the fragrance is in the air .Sun is going down as you gaze across the acre canopy toking your own genetics,
Nothing better .

in addition to the problem of grasshoppers, which eat leaves and even manage to nibble the stem, I found several ants, I don't see aphids on the aerial part of the plant, so I really think I have root aphids. It would also explain the foliar symptoms similar to a nutrient deficiency... also because, I have never had major problems with this soil, apart from a very slight deficiency of zinc, iron and mobilden, (which usually occurs in pre-flowering), due to the ph of the native soil of calcareous type and tending to alkaline, but which I have always managed to keep under control with a bi-monthly foliar fertigation of the micronutrients in question... what do you think? I'd love to hear your opinion
tomorrow I will check with a lens the roots near the collar in the first centimeters of soil.. we will see...

One of my outdoor plants has a similar problem
Or is this a magnesium deficiency?
But I have fed the plant with a bit of epsom salts.

yes, it looks the same... let me know how it goes
have you noticed bugs? is the stem collar close to the ground okay? no damage? I ask this because I have discovered that the fire ants skin the base of the stem to get to the phloem and feed on the sugars. I did not think that those small and industrious bastard insects would go that far... apart from the possible relationship of mutual help that they establish with aphids I never paid attention to ants... a google search with the terms "fire ants cannabis stem "will tell you more
