Guess the deficiency

ok since nobody guessed right
you have a mag deficiency 1 tsp per gal of epsom salt gets you there. Those leaves that are jacked wont come back so dont try to think about it.

No you dont need to use cal/mag every watering and probably shouldnt, if you use r/o dont remember if you do then maybe you should.. Cal/mag is a supplement.

For somebody to say that you use cal/mag one time at week four in soil is crazy and for you to say that is what your going to do next time is crazy, dont blindly do things that people put out on the internet. Do your research.

And checking ph run off is silly and not needed. At all. Microbes regulate the ph at the root surface I would get some microbe action going if you want to up your game. Your microbe game that is. Measuring ppm run off is just as silly and not needed if you feed it correctly but at least that will tell you where your at if you think that you have a hot pot.
it may seem silly to this guy, but it does help seeing what is coming out, the correct thing would be to dig down about an inch or 2 and mix 1 ounce of soil to 1 ounce of water and stick the pH pen in and measure it., that will tell you the correct pH of your root zone and you should also measure the PPM of that soil slurry as well, it tell you EXACTLY what is going on in your root zone. Everyone on here tries to act like a pro with their advice, but everyone has their own way of doing things, the only way you truly learn is trial and error

I think you are probably over thinking the entire thing anyhow, it really just looks like the natural run of things, the older leaves tend to yellow up like that toward the end of full bloom

Hes around week 4. Shouldn't be happening yet.

It doesnt look like its P in the pics but they do like their P. Its mag and they are crazy for the mag. 1tsp of epsom salt will get you about 250 ppm of mag per gal. Notice I didnt say add cal/mag. Mag makes the plant green nitrogen makes it grow.

And you dont want to feed it any nitrogen at this stage of the game at all, even though if you feed it nutes something will have nitrogen in it you dont want to feed it any if you dont have to. Im talking about specifically feeding it nitrogen.
That last part is just plain silly.

Also chlorophyll makes a plant green. Not mag, not nitrogen. If the yellowing was spotty or in between veins sure I'd agree. But it's the whole leaf yellowing and starting at the bottom. Centralized at the bottom and hitting main fan leafs. Didnt feed, so medium is running out, could be a compound issue. Red stems also is more times than not a ph def.

I had a blueberry do this last time around and it progressed to the center fans and stopped there, but the strange part about it was that whenever I fed the plant, the affected leaves would go from yellow to lime green and a few days later back to yellow and the whole time they that inter-veinal mag deficient look about them, I chalked it up to pH because those leaves lasted the entire flowering stage

Runoff is always a great thing to keep track of. Ppms ph ect. You remove alot of piss and shit your plant have already used up as well. So I agree mc.

Ya I've dealt with alot of things like that in the beginning of my adventures lol. Genetics had alot to do with any problem I had along those lines anyways. Since I've switched to less feedings and use one 2 part line, as well as some molasses, I dont ever have any issues honestly no matter the genetics. Oh and i feed nitrogen in flower as well ;), week 6 and they like it. Just throwing that out there for the other guy lol

What 2 part line do you use?

Just double checked my dates and the seed actually broke soil surface on August 12. So I’m only on day 53. The first picture is from August 20 the next picture is September 1. The last picture is September 25. The September 25 picture is when the problem became very noticeable.

Week 4 meaning week 4 of flowering not total days in the grow. But I use Jack's. They have a veg. And a bloom. I add molasses towards the end say weeks 6 through 8 or till the end whether it be 9 10 ect. I occasionally use root boosters but that's it. I keep superthrive on hand for a foliar spray every now and then as well. Has every micro and macro nute you'll need. I feed once a week to week and a half.

It very well could be genetics because the problems I had with that one is from the same breeder my current gear is from and I am having the same issues with this strain. :wall:

I have learned a lot from using the organic nutrients that I use, but sometimes it's more difficult than it needs to be and I want to just switch to a simple 2 part line, but the quality of end product is why I don't.

I’m with you. This happened on my first grow of the same genetics. It happened later in the grow. The fact that it has happened to you as well pretty much seals the deal. I still want to try and give it everything it needs; including the Epsom salt. I’m listening to you as well.

This is the last auto I’m growing for a while. I’m growing peyote WiFi and gorilla WiFi next from the same breeder.

I wish you the best of luck, I know it can be frustrating but it will pay off in the end :peace:

Whats the center molecule in chlorophyll production.?

And I didnt say nitrogen and whats a ph def.?

and plants dont want nitrogen in week six learn what a plant wants at the different stages of growth please.
