Any ideas what's going on here?

i'm not 100% sure, but it looks like the beginning of a phosphorous deficiency maybe?
can be caused by a few things, ph being off, low temps, has it recently started getting colder where you are? is it sitting on a bare floor? could be something that easy to fix, just get it up off of the cold floor

Calcium deficiency. May need cal or ph is off. Usually too low. Hard to correct at this stage. Have to build cal from veg. But should up it a bit to help limp to the finish. Next time start building up stores in mud veg. Be sure to get ur ph straight. Otherwise adding won't help much.

you think so? that was my first thought too, but after looking at it longer, it just doesn't look right for calcium...

Yup. I was plagued by this my first couple grows. No cal/mg. No ph meter. And no internet to help out. Ha! Early 90s. Made me a better grower though. Cal is weird. Shows weird, especially now with led. Shows anywhere on the plant. Trips up alot of growers. 99% sure thats the deal here. Bet the bigger fans look even more like it.

Bloom boosters are usually the culprit for Ca at this stage. Not saying it is Ca, need better pics in better light to confirm.

True! Not a huge fan of the bloom boosters. I use them sparingly. A dose or 2 in mid flower or if I see the beginning of P def. Don't need em anymore thsn that. And like you said, sometimes cause other problems.

I do have a PH pen AND use tap water and I PH every feeding to mid 6's. But i've heard mixed opinions on cal/mag. Some say if you use tap, you dont need cal/mag, others say still use it. Should i introduce more cal/mag to the feeding schedule? And you would also be correct in assuming that the larger fan leaves are also showing signs, even more prevalent then the bud pic I posted.

So are you ph'ing ur solution? Cause that won't always get u there. Its the ph of your soil that matters. Some spots that I've grown, my solution has to be in the 8s to get the soil right. The problems I mentioned, early in my grow life, had me studying and mastering ph. Now I can just use the ph of my solution to know where Im at in my soil. Runoff can be helpful, but to be sure you need a soil pen. Ime, runoff is usually a few 10ths higher than what the ph actually is. So you can use that as a reference. If you water slow and purposefully, then you can rely on runoff somewhat. But again, subtract a few points. So if your runoff says 6.5, its likely 6.3 and will creep down a bit as things dry and soil chem changes. Cal needs to be in the high 6s to be used correctly, in soil. Always add some cal/mg. Even with tap water. Even if just a small amount here and there. Your not likely to over do it. And once you have problems with cal, you are in trouble. Once you see cal def, you have been deficient for weeks. Its hard to correct and adding alot to compensate will really fuck u up. 6.4/5 in veg and 6.8 in flower are the right marks for soil ph. Sounds like ur in soil? What kind?

Not at all trying to come off as a douche, but what's with this ph'ing soil? It's unecessary and not good for the microbes. Ph shifts kill off colonies.

Im assuming that he's using just base soil and ionic nutes. In this case, its absolutely nessesary. If he had microbial life, I imagine that he wouldn't be in this situation. Most living soil growers do not understand ph, because they don't have to. When using salt based nutes, its a must. Of course Im assuming, just based off the problem and his limited description.

You can use microbes and salt based nutes together, you just have to remember to feed the microbes every once in a while.

I don't see the point in running soil without microbes, but I suppose you're right in that case. It would make more good sense to just run coco that way, be faster too.

I don't really believe that. Microbe counts when using salt nutes are minimal. Just microbe companies passing out bs as to not limit their customer base. I agree about using microbes in soil, but gotta be using organics or living soil. Otherwise a waste. I know lots of people are using with salts and Im sure to unleash the hate, here, with this post. Lol! But the numbers would say that they are being chumped!

I use microbes with salt and organic ferts in soil, coco and DWC. They don't hurt the microbes, but they can't feed on the salts, so they don't help either. Doesnt affect population either. Ph swings, temps, oxygen/water are the only environmental factors that bother them, salt nutes don't.

Salt nutes def effect the populations. Quite a bit, actually. Its a waste. You would be better off learning ph. This is based on actual numbers. It's not a theory or anything. My growers club here in NE has access to tests/equipment that shows this. Of course there are other variables that may effect the results, but it's consistent enough to make this statement. My life right now, dictates that I do not go on FB, which is where I can get this stuff. We got our monthly meeting, second week of Dec, I will get and post some of this stuff for you to see then. We are using Microbiometer.

Holy mother of ........that’s probably what has been wrong with my girls!!! The cold floor not the deficiency. I had/have Cal deficiency. I wish I had thought of that or somebody had told me. I’m usually pretty smart but why on earth did I not think of the cold from my concrete garage transferring from concrete to tent material to pot?

Oh yeah I know why, my harvest is 4.5 weeks cured now and is making me stupid

That’s what is going on with mine right now. I think my cold floor might be having a lot to do with it too.

I’ll be watching this one, let us know how it turns out and what you did to correct it

Excessive salts will definitely kill your shit.

That pic looks like a P deficiency to me.
