oh, no! redish spots starting to appear

[bigfun]

Wow, that's great!

o clarify, the direction of the CalMag+ *did* specify 5ml per gallon for foliar feeding, and so I just mixed ~1ml in 1/2 quart and misted on my plant. I did that before I read this, so I may go back and get the underside.

How many times/frequency should I foliar feed?

I also picked up one of those test tube/drip ph kits at the hydro store, and ran a few tests. I did flush the plant, and catch the very first run-off from that and the ph was 6.0 or even under a tad (similar to what the probe said). I know this could be part of the problem, because below 6.0 is where you get the calcium lockout. Maybe a disadvantage of perlite is less ph stability from the soil. However, I read so much about ph and soil, my head spins a little. This is such a thread. From "It's never needed. what other plant/farmer/garden plant in soil the world to they adjust their ferts with ph up/down before they feed" to the otherside, "it may actually matter" ...

So, I took ph of straight tap, which ~7. And I took ph of my nutes immediately mixed, it was ~5 !

Now, I know good soil is supposed to balance ph, but not sure about HF. What I did also read of interest, that when you bubble your Earth Juice feed mix 24-48 hours, the ph comes up, which is recommended for Oxygenating the water as well.. My earlier feeds, I had been doing that, but the last couple I added nutes immediately before feeding. I'll test the ph of the feed after brewing to double check, but I'll be sure to start letting the feeds brew appropriately.

The other side curiosity is the possibility that it is iron toxicity. The red spots do seem a little worse today, some areas of the plant are more affected than others.

THanks again!

Oh, in reference to adding a drop of liquid detergent in place of a wetting agent. This is not advised at my timeframe (3 wks into 9-10wks of flowering) then?

 

[bigfun]

Here is an update.
The problem still seems to be getting worse:

The problem seems to be affecting some areas of the plant worse than others, and mostly on older growth.




So, yesterday I had flushed several gallons of tap water and then finished with a fresh mix of nutes as I mentioned. The nutes had a ph of 5 (maybe a tad lower) when I fed. This morning, the soil is still pretty damp, so I stuck my soil meter in and it said ph of 6.5-7 ... so I grabbed a 5ml sample of that soil, and put some clean water in it and let it sit for 30 minutes. I then checked the ph of the water from the soil with those ph testing drops, and it was 6.5-7 -- so what I understand about the soil stabalizing the ph seems to be happening? (and maybe my soil probe is good?)

I did foliar spray the underside this morning as well. Hopefully I will see her turn around the next couple of days.

And thanks for the heads up on not just adding the CalMag+ (which I, of course, did last night before I read your post). The only other ingredient listed on the bottle is iron, and the EJ Microblast does also have iron. I will switch out between the two as I feed.

...yeah, skip the detergent of course, if you have a wetting agent- much less other nasty stuff in it! ...otherwise, foliar must be done with caution when in bloom, potential mold issues largely, but you're pretty early in so just make sure she's dry by lights out,...2-3 treatments over a week, plus soil dosing is the ticket; zero chance of this being Fe-tox,... Feeds are usually acidic, so adjust up if needed,... A cautionary note about all soils: many many reports of low pH on them, confirmed by me by measuring in the stores themselves! I shun their soils now, though others seem to get OK batches...good soils will have some form of lime in them for buffering, yes, but often it's too slow acting, or not enough, or gets exhausted too soon,...or the soil is jacked already regardless!
OK -- proof that diagnostics can be a bitch sometimes! ...Ca defc. tends to have scattered finer spotting, sometimes right along the veins too, and what I saw earlier fits this best; certainly you can have more than one at the same time... these new pics show a more distinct pattern, particularly along the margins right at the "teeth"... what I'm seeing here looks like K defc.--

(more pics here: https://www.autoflower.org/threads/quick-and-dirty-deficiency-picture-depot-expanded.43164/
....that flush may have helped the pH some, but adding in more acidic nute's will work against it, so best to adjust before you feed with a product made for this; what do you have for bloom nutes? Do you happen to have a hearty P-K booster as well? This will help boost up the K fast,.. your pH seems okay for now, but again, the skinny probe meters are notoriously inaccurate,... yes, the Accurate 8 works on the same principle, but the probe is much more robust and better made,...

Oh, no!!

Well, I'm using Earth Juice Bloom(0-3-1) and using between 5-10ml/per lit. Which is normal dose.

I'm using 5 Earth Juice products (Grow, Bloom, Microblast, Catalyst, and Meta-K), and the odd thing is I was also using Meta-K (0-0-5), which is what I thought I was *overfeeding*, because I was mistaking it for another micronutried proudct and adding 1tbps per gallon a couple of the feeds one the flowering started. So, it seems to me that I may have gave it too much K. SO, I'm confused and feel a little lost.

How should I best approach this?

 

[bigfun]

Come to think of it, I probably didn't really give it THAT much N. I only added it two or three times around week 3.

More details on my feeding schedule. I was using this schedule (except no Hi-Brix or Hygrozyme) :
EARTH JUICE SCHEDULE:

----------Cat-----------Micro---------Grow---------Bloom--------Hi-Brix--------Hygrozyme

1veg------5ml----------5ml------------5ml
2veg------5ml---------5ml------------5ml
3veg------5ml---------5ml-------------5ml----------------------5ml-------------2.5ml
4veg------7.5ml--------5ml------------7.5ml----------------------5ml-------------2.5ml
5flwr------10ml---------5ml------------7.5ml---------5ml-----------5ml-------------2.5ml
6flwr------10ml---------5ml------------10ml--------10ml-----------5ml-------------5.0ml
7flwr------10ml---------5ml------------10ml--------10ml-----------10ml------------5.0ml
8flwr------5.0ml--------5ml------------10ml---------15ml----------10ml------------7.5 ml
9flwr------5.0ml--------5ml------------10+ml--------20ml----------10ml------------5ml
10flwr------------------5ml------------10+ml------20-25ml---------10ml------------2.5ml
11flwr------------------5ml------------------------20ml------------10ml
12flwr-------------FLUSH

I mistakenly thought my Meta-K (0-0-5) was Hi-Brix(0-0-3). I started adding it week 3 but upon closer review it really could not have been THAT much more K, because the nute ratios are similar.. (and maybe these plants are really K hungry). May plants are now just over 3 weeks into flowering.

Nute rations:
1Tbs EJ Grow (2-1-1), 1Tbsp Microblast (Contains Magnesium 0.50%; Boron 0.02%; Cobalt 0.0005%; Iron 0.10%; Manganese 0.05%; Molybdenum 0.0005%; and Zinc 0.05% in an organic base.) and 1Tbs Catalyst ( Contains enzymes, hormones, vitamins, amino acids, nutrients and surfactants). (At one feeding, I switched out some Alaska Fish fert (5-1-1), with grow (2-1-1), and some other strains I was growing were burned by too much N, but not this plant. )

RIGHT NOW, brewing for the next feed I have just under a gallon with
1tsp of CalMag+ (2-0-0)
1tsp of Grow (2-1-1)
6tsp of Bloom (0-3-1)
2tsp Molasses.

That about 1/3 dosage for the Grow, and about 1.5x dosage for Bloom.

I can add more potassium with Meta-K (0-0-5) ... I just want to make sure I'm not screwing anything up.

But I would sure like my buds to get fatter!! My first grow, and this was the only good plant out of 7!

Help me, OB-1

Thanks!

Here are pics from the worse areas of the plant today.

 

[Chester]

When I look at your photos I see a hungry plant (hungry for a bloom nute containing 'N' ) that is also suffering from a slight CalMag deficiency ... you mention brewing your nutes for the next feed ... how long have they been mixed and was letting it brew in the Fertilizer's directions ... ?

 

[bigfun]

Chester, thanks! ... the directions do not say to bubble but I was recommended to do that, through this article and research.
I've read alot the last few days about Earth Juice and ph, and the bubbling. My current batch, I've been bubbing for 48 hours, and I checked the ph this am, and it was still 5.0 ... so I'm not yet experiencing any rise. I've read through some folks that also experience this problem, and it's suggested to pay attention to the order you mix and bubble... it's a little confusing.

My best guess is that somehow I had too much of something that caused lockout, and that flushing helped a little.

I hope I'm diagnosing this correctly. What you say a "bloom nute containing N" ... you are saying a Nitrogen deficiency? It looks most like a Potassium Deficiency, like here. Esp. the burnt tips in that 2nd photo.

Just still not sure of the best route. It seems to have stopped getting worse, as quick...

 

[Chester]

It looks like a Potassium problem ... Bloom nutes should cover that ... but it looks like it could also use a little N ... some bloom nutes have it and some don't ... just about anyone here is better at diagnosing deficiencies than I am ... I try to avoid deficiencies so that I don't have these frustrating times ... good luck w/ it ...
