Help please...leaf death

[Bugeye]

Assuming your ph is okay, I would guess this is a minor lockout and not a deficiency. If it is only happening in the summer, are you running a few degrees hotter? That will increase your water and nutrient uptake and could push you into a lockout that you don't see in cooler temps. I'd guess potassium is being locked out from the look. You don't normally get red stems, do you?

Everything gets more sensitive in flower and the plant is quick to rob those low fan leaves so I think it is probably a minor issue. Cutting back your nute rate just a bit would probably be where I would start. If that didn't work I would run a soil test just to get some better data points. Good luck!

You changed your fertilizer. I wasn't very impressed with jacks tbh. Is jacks citrus for fruit trees? They always lack some micro nutrient molybdenum, boron ect.

Jack's Citrus is da bomb for MJ, been usin it for years

I fixed it. Everything is ok.

Were the damaged leaves from farther down on the plants? Older leaves cash-out it's no big deal when it happens, you're half way into flower, not much you can do anyway but I don't think it's a problem.

Haaa, see! Those older leaves are far away from the light and they shed them as the plant matures.

Yeppers this is the most solid post IMO as both damaged leaves are sinks

Definitely not a big issue but curious it is only happening in the summer?

I don't think I've ever had a synthetic nute grow where I didn't see some element of this happening. I've only been able to keep lower fan leaves healthy throughout entire grow with a really well dialed in organic soil and tea applications that kept the buffet fully stocked for the plant to pick whatever it wanted, whenever it wanted. So I tend to think it is the nutes being just off a touch from what she needs for a "perfect" grow...whatever that is!

Why didn't you tag me? That's fucked up dave.

I seen this post early this morning and noticed you weren't included in his call for help.

That must have really hurt, I feel sorry for you senor sol..... you reached out to this member and treated him like family with love and support, and this is what you get in return?

You're a good man to keep the high road....hang in there and keep strong

I believe in dave. He may not want my help but I'm not ready to give up on him. He really really needs me he just doesn't know it yet..

Thanks all... Lots to cover.

hmmm watering every 3-5 days....maybe alot of water...back er off to dry out in 2-3 days. Its hard to explain why you'll have a perfect grow last time and this time you are doing the same routine and getting different results. This is the shit that makes us go "huh" ....but these gals will have different needs sometimes, this one is a root problem (build up, soggy roots- cant uptake the nutes etc). Like doc and whitebb said...lets start by giving less water and see how it goes from there

Yeah...I dunno. My watering practice has never been an issue. Peat is pretty easy. Yes, I soak my peat each water but all runoff is removed and they dry out quite thoroughly between. Ultimately my roots have always been healthy looking. Last grow did have a little of this brown edged yellowing, but not as much nor as high on the plant. Examining the differences you allude to though might be key.

Can you post a pic of the whole plant ?

Here's a couple shots of 1, Day 31 of flower...keep in mind that this was cleaned up 2 days ago when I watered.
Whole plant:

Closer:

Closer still:

It's really kind of a nice showy girl... Hard to see but she has 6 nice similar size colas:

Oh and one shot Señor Sol:

Had a really nice grow last grow with it. That and the Epson I think created some great tasting smoke.

The reason for the switch was that @Bugeye turned me on to something Lowenfels said about too much Phosphorous interfering with the effectiveness of the Mykos I was now adding. His book did not narrow it down to Ppms so I actually exchanged a few emails with Lowenfels. He told me 80 ppm. I had been using a 20/20/20 and so the Jacks Citrus 20/10/20 got me where i wanted to be.

I certainly want to be with you. The increased death rate and height it is achieving is what got me to post. Let me know if the new pics still fall in line with your thinking.

Don't think "perfect" was my word. . I am not needing to be green all the way. I think most are starting to line up similarly to what you describe. Yours is also almost as calming as the pinch hit I just took.

Did you miss the part in jeff lowenfels book that says synthetics kill off microlife.

Yah mon, the plant is so deep green that I can't imagine that you have any type of deficiencies.

loving the shit out of building soil and then water-only. Def become my style of growing!!

 

[abe supercro]

Dave are your fans still blasting when the lights out? that can dry and desiccate leaves. rotating plants that are right in front of a fan helps prevent this.

It is on my reading list, but no. My simplicity in method is hard to steer away from. The mykos I started last grow certainly seemed to have a positive affect in my synthetic garden. .

Starting this grow i did add an oscillating fan but it mainly is blowing on the canopy. I removed a box fan blowing below.

Edit: Wanted to add that the new fan IS on a timer and only comes on for a split up hour worth of blowing in the dark.

 

[abe supercro]

On each end of the oscillator cycle, before it switches direction, it pauses and stays at each outside cycle for much longer than what it blows past in the middle. Just consider if the said plants, are ones at outside of the oscillation cycle.


A box fan under your canopy sounds like a good thing in summer.

Also just hit me is that one difference between this grow and last is the fact that my hurricane centrifugal is constantly exhausting and thus creating a constant blow from the floor's passive intake. It was seldom needed to pull heat out of a dark room last grow. Hmmm?

Thanks old buddy. I was going to include you here and certainly would have if I needed help repairing a bridge or correctly preparing roast billy-goat.
