Leaf issue... and hey, it's been a while!

[Beltana]

Hey folks!

I meant to start a new grow journal, but I haven’t had the time to get around to that yet. (I hope to be able to do that soon.)

So…

Hi again, all! It’s been a while since I’ve been in here!!! You folks in here taught me pretty much everything I’ve learned, from building my own lights from scratch, to popping my first seeds, and I figured this is the best place to find the answers.

I finally got to chill my life a little, and got time to start a NEW grow!

I’m running autoflowers, Apple Fritter Autos.

Everything was going swimmingly! All the girls looked great, until a couple days ago.

Then I started noticing these:

I looked up everything I could find on “leaf diagnosis” type sites and charts, and got a dozen different answers. Nitrogen? Calcium? Phosphorous? Magnesium? Lights?

Growing in coco, using Jack’s, only… light seems good… (I’ve been adjusting it around just in case) ph is good… and I can take more pics if needed.

Just not super positive what is going on here.

Thanks!

Missed the growing!!!

[Beltana]

A few more pics of the same grow tent, when I still had room for some veggies in there and before they started getting, ahem, this big…

(& yeah, they are all going ouside, soon!!!)

[Beltana]

Oh and it seems to have started with some yellowing on the leaf edges, and some “spots,” kinda… here and there, like these.

The it went further into the leaf itself, between the veins, got yellow-er, then now it’s turning rusty looking. (Necrosis?)

There aren’t too many of them that are looking this way, just yet, but I want to catch whatever this is a quickly as possible so if it’s something spreadable, (I don’t feel like it is?) it doesn’t affect the whole grow.

Anyway, I moved two plants outside, to see if maybe they were just overcrowding and stressing. (That’s what it felt like to me, as a possibility.)

I’ll check on those (outdoor plants) again in a bit to see how they are doing. They’ve been out there a couple of days.

There’s a nice light rain out there now, and for the next few days, and they seem to be enjoying that.

[Beltana]

Oh & hey…

I’m gonna tag you fine folks I “most interacted” with when I was last able to participate in this forum… (what, two years ago now??? Sheesh, I’ve been away too long) because you all helped me more than you can ever know.

Hope that’s okay!

No pressure to answer, just wanted to see if you gurus had any words of wisdom, or an “eye for the why…” and also wanted to kinda catch up and say… “Hi!”

Hope you all have been having some wonderful, successful l, beautiful grows, and I am SOOOO looking forward to diving back in!!!

Well I’m following along because I’m very interested in the answer because those spots on your leaf I noticed on mine this morning after feeding a tablespoon and a half of Epsom salt yesterday so I’m really wondering if it has something to do with that so I can see what’s going on with myself

[Beltana]

For sure.

Follow along!

That was one of the first things I read, was that it could potentially be a Magnesium issue.

But I also saw (as I kept digging): boron, iron, and other things, as possible problems listed on the various “charts” out there. Honestly, I saw nothing that looked exactly like my leaves look, so I find myself at a loss.

But my question was like…

Okay. If it’s 1) the epsom salts…

“Do my plants need MORE Magnesium, or LESS??”

I don’t feed them quite as much as you do. Actually, with the suggested Jack’s 321 mix, it only calls for a quarter of a teaspoon, per gallon.

I’m going by the old “recipe” I had two years ago, and the one that was suggested to me by another friend, that they got from Jack’s, when measuring by the gallon by teaspoon/Tablespoon, rather than by weight.

I got a tiny little scale, to measure by weight, but it was a pain in the … to do that for each and every gallon jug of solution, and also one of my kiddos messed up said scale, and its out of calibration, so I found this, to make my life easier.

The suggestion from Jacks was this:

So…

That’s how I’ve been doing it from the get go, with Jack’s, anyway.

Your nurtient solution might be different. It sounds like it, if you’re using that much epsom salt.

Maybe I’m not using enough, or at least possibly I’m not using enough, right now.

Whatchya using, as far as nutes go, if I might ask?

Let’s figure this out!

Maybe we can do it together.

[Truetopath]

What’s your ph running? And what media are you growing in? When I use jacks I go by weight not tsp etc. Dials it in a bit more I think.

[PharmerBob]

What’s your input output? Ph and tds? Like above stated your plants could just as easy not be absorbing nutrients due to ph not being correct.

[Beltana]

Ph…

I try to stay between 5.5 & 6.5, but I shoot for 6.1-6.2. (That’s what it was this morning.)

I am growing in straight coco.

[Jayjay504]

@Beltana well that was really my first time using Epsom salts LOL and I read somewhere to put between 1:00 to 2 tablespoons so I put a tablespoon and a half LOL I use Fox farm nutrients

[Beltana]

Ph… (I mentioned this above but I’ll add to it…)

I try to stay between 5.5 & 6.5, but I shoot for 6.1-6.2. (That’s what it was this morning.)

I am growing in straight coco.

I haven’t measured “output,” I’m not sure exactly what that means, (you mean runoff?) and I don’t think I’ve ever measured that.

(I’ll have to go looking back through my old grow journals to make sure.)

I’m not sure if that’s something I can just go ahead and do with this Ph meter? (Probably not?)

Of not I guess I’ll have to get something ride that measures that. (Or I’ll dig around in my drying closet and see, it feels like I bought something like that before, likr a simple “tds meter?” but I guess I never really used it.)

I have an Apera PH20 pH tester.

Looks like this guy.

And hey!

Good to see you again.

You started off by helping me with my lights!

[PharmerBob]

Yes runoff, what goes in must come out, it will tell you a lot about what is left behind or not needed at all. What goes in should be equal or less than output. Oh can also fluctuate , it’s nice to have as much data as possible to make the best possible decision on the issue

@Beltana

I am growing in straight coco

Did you buffer your coco with cal mag?

[Growdoc]

@Beltana

you mean runoff?) and I don’t think I’ve ever measured that.

Better get used to checking runoff in coco!

[dbrn32]

I don’t see a magnesium deficiency anywhere, maybe a couple indicators that nutrient load is a little hot with burnt tips, and some dark leaves.

Not sure how you’re treating coco, but it needs buffered, fed to healthy amount of runoff frequently, and probably best to ph at 5.8.

[SausageMahoney]

I concur with @dbrn32 . I run Jacks/coco. Try to keep the pH at least below 6. Also im realizing that some can take thebfull strength 321 and some get burned more than other’s. I run a few indoors and a few outdoors but all jacks/coco. Back the pH down as suggested and see if the clears up. Good looking grow, by the way.

[Underthestairs]

Definitely ph 5.8-6. In all honestly when I am doing things my version of “right” I’m only getting runoff on Sundays to make sure I’m flushing things out a little. I’ve done 2 full grow cycles without a fish things went ok, but healthier with a weekly.

I don’t see anything looking deficient to my eyes. Nice plants. It’s there any chance that was rubbing against anything with a string fan?

[Beltana]

Thank you! Much appreciated.

[Beltana]

Awesome, thank you.
