what will it be?

It seems to be a cal/mag deficiency or maybe a very acidic pH? Do you have numbers or a table that you use as a guide for watering?
It shows good LED quality to have that many pistils in quantity and thickness.
When it’s like that, the plant works more, and if it eats more and asks for more… maybe a little cal/mag can fix it, and if it’s not that, it could also be phosphorus.

Hey!
It looks like a slight calcium deficiency. Those rust-like spots with a small yellowish halo are quite typical, especially at the beginning of flowering when demand increases.
I would first check the pH to ensure there’s no lockout, and if you’re not using CalMag, I would add a bit.
Happy growing!

Hi, thanks for answering, yes it’s very likely that’s it, in the last watering I didn’t use cal-mag, I didn’t imagine it would show deficiencies so soon! Haha thanks, the next watering will be just water and cal-mag with algae, I hope that solves it

Hello folks, thanks for answering, indeed the last watering was only with MPK without Cal-Mag. I didn’t imagine that a single watering without Cal-Mag would be enough to show deficiencies, that’s

I just watered only with pH 6.2 water and 2ml*L of cal mag which gave me an EC of 1090 and I added only 2gr of MPK (for 7L) which added 200 EC starting from water with 400 EC, that is to say, 600 EC from calmag and 200 EC from MPK. I don’t want to use algae because I saw they contain nitrogen, but the deficiency progressed from yesterday to today, the rest are beautiful
but yes, the hairs are really very thick and big, they surprised me too! well, they were in vegetative stage for 1 month with LST, I took almost daily photos of the whole process but I didn’t do a Growlog, I will do it next grow, regarding the fertilizer, when I switched to 12-12, I used TopBloom in the first two waterings for the transition because it has a little nitrogen, then only MPK and algae, and after that only MPK 0-52-34, I no longer use anything with nitrogen, not even in minimal doses, 0 nitrogen.
I don’t use well-known brands, instead I look for the ingredients and buy those, but thank you very much for the comments about the hairs, I’m very happy you think so

Yes friend, I think that must be because your cultivation guide is very good… So you don’t use branded fertilizers, you use common fertilizers or something like that?

That’s right, I buy much cheaper because, according to me, between 1/4 and half the price, sometimes even more, is for the brand, but they don’t contain anything special compared to others, for example, delta9 is MPK like the one in the photo I showed you before, along with hormones, which are provided by algae.
to naturally improve the hormone balance. Furthermore, in theory, they help with photosynthesis because algae, being in the deep ocean, are more efficient than other plants since light barely reaches the bottom. I also use the same as anyone else, but they are not growshop products; let’s say I use white label brands hahaha. Also, some plants have hormonal treatments during vegetative growth with cytokinins and gibberellins, although not the hairy ones, but one that ended up with a beneficial malformation of 3 shoots per node.
But what really makes a difference is the MPK, which is 0-52-34: 0 nitrogen, which it no longer needs; 52 phosphorus, which is for the creation of new flowers, shoots, calyxes; and potassium, which is for fattening and sweetness. The product I showed you before that I use has very high percentages of phosphorus and potassium, far above others. It cost me 20e on Amaz and it’s 1kg; I have enough for many years of cultivation. The same with the algae, 1 liter cost 12 euros and will last for many cultivations. I don’t work with clones, but if I did, I wouldn’t use Clonex, but rather AIB, which is its active principle, and so on with everything.

Great friend, you’ve just answered a concern I’ve had for years… are cannabis-specific fertilizers really better, or are the more natural ones, already proven with multiple types of plants, better… I think your experience has made me understand

Hello Growlings 
,
The question about the right fertilizer has always been there, I believe. For everyone who cultivates cannabis for a longer time.
The assumption is completely correct that in most fertilizer types, especially with special cannabis fertilizer, the same active ingredients are present as in conventional fertilizers. Only, the carrier substances are different. Which, well, are good for cannabis. I’m thinking of substances that don’t affect the taste or substances that facilitate degradation in the substrate.
But…
I’ve always used a very simple, cheap fertilizer from the drugstore since the beginning. It contains almost 1:1 the same main active ingredients.
And it has always ensured super growth for me. Only during the flowering phase do I specifically use brewer’s yeast as a booster. It’s natural and makes nice thick Bud’s. And you can get it cheaply as a powder in large quantities.
So, from my point of view, I’m always in spirit with everyone who doesn’t always use only the MEGA super duper cannabis fertilizer.
However, the quintessence for me is…
Everyone has to make their own experiences.
Everyone has to find what’s best for themselves.
It’s like everything in life. Nothing always fits everyone. That’s how it is with people and that’s how it is with our “Lady’s”.
@3xt3nd3d I think you’ve had a really great Grow so far! Yes, sure there are some nutrient deficiencies. But the way you’re taking care of it. And how nicely @Tolitos is helping you right now. I think you’ll definitely get a really decent harvest out of it. I’m crossing my fingers for you, as we say in “Bad old Germany”.
In this spirit
Grow on

Thank you very much @Dbe for the beautiful message, I agree, also investigating these kinds of things helps to better understand the plant, how it works, what it needs, I believe that grow shop products are of excellent quality, but we can achieve the same and even better quality in other ways, and it’s a good learning experience that helps us better understand our plants, in my case, I have a lot of fun researching, I think it’s the most enjoyable part of cultivating because the plants grow by themselves lol the truth is I haven’t cultivated in a decade, this is the first in many years and I’m glad I didn’t do too badly, a shame about the calcium deficiency, it’s the first cultivation under LED, and the first with Fast versions, I didn’t think a single watering without cal-mag would be so serious, but we learn from everything. Calcium is not mobile, so the error has been quite serious. I sprayed the largest leaves with cal-mag using a mini atomizer, making sure not to touch the buds, hoping it wouldn’t progress further. Since calcium is not mobile, it will take at least a couple of days to take effect from the roots. I hope spraying the large leaves relieves the deficiency as soon as possible.
I also use brewer’s yeast like you when I cultivate organically, it’s very effective despite the smell lol but it’s very effective, I’m now trying inorganic cultivation, I still haven’t decided if the next one will be organic or not, I doubt it given that the seeds I have are high THC varieties and not good flavors and aromas, but it’s not decided yet
In this cultivation I did the best I could, after so many years I’m satisfied and I hope everything continues well, I also think it’s very difficult to get a complete cultivation without a single error in 3 months, but we try, we always learn, and the help of others is also invaluable
Thank you very much for the message and the encouragement!!

Hello dear grower friends
It makes me very happy to know that there is a community, a desire to support and teach everything, especially by sharing experiences… which, in my view, is pure gold.
The experience of another fellow grower is my learning; it is very important to always support and converse. There is always a new topic to debate, to avoid that error, that deficiency, or perhaps some unstudied theory… in this world, even trichomes and color are extremely important; I’ve even come to think that drying and curing account for 75% of the total harvest result… but also the vegetative or flowering phase, everything has its theory, its part, its magic.
It is an extremely beautiful world, and even more beautiful and great when there is a truly interested community.
Thanks also to both of you, you help me better understand what I’d like for my future grows and more… I hope to continue sharing my grow#3 and any experience I can share with all HGrowers 
Happy day to all and happy gamma 3 missiles
