Pretty (scary) Aucuba looking discolored leaves

Dear GentleFolks,
I am growing indoors
I water when the top inch of soil seems dry. I always add something to the water, Molasses, WCT, SST, AACT.
I use custom made LED full spectrum light (ie not pink light).
The medium is organic homemade soil (might be a tad bit acidic).
The girls are on the 19th day of flowering.
The temperatures are a bit on the high side. 87 when light is on and 78 when light is off.
I noticed a couple of leaves on the top of the branches with this pretty pattern.
Any ideas? The plant is strong and flowering nicely (maybe even better than her sigglings). I am not worrying too much. I will as soon as you guys tell me that dooms day in tiptoing on my girl's leaves.
Variegatedly yours,
M

Do you ph? i had a plant like that once before i started phing and realized my waters like 7.2

Cannn, I never bothered to pH. I have several old school super skunk growing and only one seems affected.
Having said this, it seems to be spreading to the cuttings. Yet, just 2 out of many. I have 2 or 3 but never have the buffer solution to calibrate the devices... I am growing in soil so I assume (ass u me) it will eventually balance out...
pHmeteringly yours,
M.

Your soil itself could be out of balance. Thats actually the more common problem with ph ive seen since a proper soil will buffer the water put in to the ph of the soil. even if its not your ph you should start testing. I had years of problems with ph before i got a good meter. Soil ph can be adjusted and it can absolutely be off

What kinda soil?

I have had a few do this over the years and its usually only affects one plant only (USUALLY) but my issue was very dry and warm conditions accompanied with too much air flow directly across it from my fan and intake port . This may not be your issue but it was mine and since its (USUALLY) only affecting one plant I typically ignore that its something serious and think in othet directions like maybe environment ect. Just suggestions, hope you get it squared.

I have a fan in my cab directly by one of my plants blowing it like crazy and have never noticed anything like that. That said my rh here is very high

It is a custom made soil.
30% volcanic red porous volcanic stone I got for free. I am not sure but I think it is called pouzzolan. I used it before for other plants and it is fantastic at aerating and holding nutrients
30% sphagnum
15% organic potting soil
7% river sediment ok with organic farming (weird thing I stumbled upon on a trade show)
7% worm compost
3% biochar
3% volcanic basalt
2% aged pin bark
1.5% zéolith
1% kelp meal
a tad bit of frass and epsom salt
I think my water pH is 7.2. So with the bark and the sphagnum I think it should balance out.
Right?

Sounds awfully familiar! My conditions are not dry but too warm. one plant wearing a funky dress makes me twitch as due to lack of space I only run a micro grow.

If your soil is too acidic putting high ph water in wont balance that. at least it would take many many waterings. thats probably stressing your plant more from the constant rise above the ph they need followed by a drop below their recommended ph. Adding a bit of dolomite lime to the soil and beginning to adjust your water ph would fix that if thats your issue.

you should get a soil ph test kit, especially when you mix your own

I love your avatar btw mazer. legalize it!!

Thanks Cann One of my favorite albums of all times!
I will pay more attention to pH. I gotta calibrate one of the pHmeters and make a soil solution. pffff. I wanted soooooo bad to stay away from this.
Anyhow, this is one of the variegated plant's clone pictures. NOT GOOD! Yet it is growing ok compared to the other clones. I really wish to avoid a culling as it seems like a cutting taken from another plant shows the same symptoms.
In another tread I was suggesting breeding less potent strains but more adaptable and resilient ones. I think I will let these "different" ladies grow and see what's up.
UNLESS one of you guys know for sure this is big trouble.

Just curious...how did you come up with this mix and their respective ratio? From the way you post, it seems to me, that's a precise mix ratio. Also, did you have a soil test for your mix?

Im asking, because often times, problem with custom mix soil is they end up with high alkalinity. And it seems your mix is very high in potassium which could lock out a lot of other minerals. It's essential to get the soil/mix tested then you can customize your nute according to whats in the soil.

Just my opinion.

Xs, I should indeed get the soil tested. my recipe was based upon previous gardening experiences. mind you they were neither Rols nor No till. They were much more simple and designed for veggie gardens but worked wonders.
The ratios come from a scale I used to keep track of what I am doing, and were dictated by my greenthumb and my plant instincts. I got to say for the first grow the girls are doing way better than expected so far. healthy and fit as a chaolin nun. No problems. I have only seen the funky leaves on a flowering babe and she is booming. Probably gonna be heavier than the others. Let us see how she tastes, smells, feels.
Why would you say the potassium might be high?
I have prepared a second batch very similar to this one with a few tweaks. Any recommendations are more than welcome.
And the second bullet point after digging up my pHmeter is to get my soil tested.
Experimentingly yours,
M

Just a thought, volcanic rock/stone are known to be very high in K. Now some of your vegetables might thrive on that condition but with cannabis, toxicity of potassium can lock out essential micro nutrients such as magnesium, manganese, zinc and iron. Those lock out elements could have a combine aggravated deficiency symptom including leaf deformation of new growth.

Additionally, there's a question as to how even is the mix. When you pot that mix, a pot might not completely resemble the mix you just have outline.

Regardless this is just a guess in my part. You really have that soil tested, I think its worth it. Otherwise you'll just be stabbing in the dark when problem starts to show up.

thanks for your input XS. I will look for a soil tester... tomorrow...or noo no, right now! I am on page 50/406 of Recycled Organic Living Soil (ROLS) and No Till Thread, but will take a break to find a company that can test my soil.
Thankfully yours,

Just a side note, but I would be very leery of anything dredged off a river bottom. River beds accumulate high levels of nasties like heavy metals and pcb's. A lot of dredging operations have a hard time getting rid of the dredgings because landfills won't take it. Maybe selling for farming is a way around that.

If it came with an analysis, that's good, but if it didn't........

Just saying.

Thanks for the heads up Greg!
It did come with no heavy metals and the like. At least so says the label... but it come from a somewhat reputable organic supply store.

What strain is it? Some have known variegated genetic markers that pop up from time to time...especially if theres an availability issue from pH out of what.

Just a thought, but I had some similar issues with a fresh batch of soil I'd mixed up. I upped the ratio (mix of gypsum/lime/oyster shell flour) and things improved drastically.

Well Tangerine, it is Super Skunk from sensi seed bank someone brought me from Amsterdam out of the 10 beans I popped half of them sprouted and they were all ladies!
It also was HELLLLL to clone. but my DIY cloner might be the problem as I use a fogger (high heat) that has a little red led on it when working. it is in a tub with water and bubbler. I ended up using a cheapo rooting hormone and it did the trick.
I have serious issues withe climate control in my tents. will try to address this asap. and will be more carefull with pH. and get my soil tested.
that should help I guess.
