Gone for the week and came back to a few deficiencies. Could us help diagnosing the problems!~

[Cannabinoid Connoisseur]

Hey all,

Left for Christmas week and came back to these sick babies! They were getting a timed-release of water each day, and they got slightly over-watered. The pH of the water when I left was ~6. When I got back it was nearly ~4.5. Not quite sure what happened there, but I usually don't pH my water until right before I add it; guess I'll continue that practice to avoid fluctuations like this from leaving it out. Secondly, the runoff was ~7.5. I don't have a pH pen, so I've been pH'ing as best I can with drops, the pen is the next on my buy-list.

Day 17 - Nirvana Short Rider
This one is looking beautiful, just a small deficiency I think

Day 23 - Nirvana Short Rider stunted at germ due to fused cotyledon
The stem growth it developed to overcome its mutation is really interesting to me. The stem in the first shot toward to bottom right is taller than it is wide... pretty cool! Any idea about the deficiency?

Day 17 - Mutant Nirvana Rando
The growth seems to be pretty good on this, but the yellowing is obviously concerning... ideas?

Day 28 - Unknown Bagseed
I've got high hopes for this one (pun intended) because the purp looks great on the veins and stems.
My guess is that she's just hungry. I couldn't feed her while I was gone, and she was on mild fish ferts before. Suggestions on what to crank the dosage up to so I can catch her up? It's a 5-1-1 mix. Not sure about the droopage and curvature of the leaves... She does have some healthy root growth though :wiggle: Don't plan on transplanting just yet, not wanting a big yield out of this plant, just playing around with her (same with the other plants in clay pots).

Day Unknown - Bagseed
just screwing around with this little guy to learn techniques. Still curious about the deficiencies though...

Some LST to start spreading out her future mini-bud/ball sites

Sorry for the long-ass post :jaw: Thanks in advance for the help, I know I'll learn a lot from the advice!

Hope you had a Merry Christmas!!

You've got a lot going on here with different plants displaying different issues. When you left for Christmas, did the water you left contain the fish mix? If so, besides over watering, that could be an issue. Fish nutes are organic and organic nutrients should be used within a day and not left to sit. I expect that's why the pH went so low. I've left organic nutes sit and within a day or two they will go bad.

The one with the purple stems is showing some early signs of phosporus deficiency with the browning along the leaf edges. While purple stems can be genetic, combined with the browning edges indicates you are lacking in P. You stated your run off is 7.5, so I suspect your soil pH is off and your nutrients are being locked out. If that's the case, and the same soil was used in all plants, it could very well be the cause of all your issues. I'd be curious to know the pH of both your feeds and run off to verify that. Also, what soil are you using?

The two bagseeds were planted in some basic potting mix that we had lying around before we really got into growing. The three nirvana plants are in a 70% OF 30% Perlite mix

I didn't put any emulsion in the water reservoir before I left, I figured it wouldn't last a week. Glad I didn't. I had pH'd the water to ~6 before I left though

Hey CC- ..wow, hate to say it, but Muddy's right, there's a full scale trainwreck happening here,... problem is, when there's mulitple defc. symptoms showing, and accurate pH reading are uncertain,, things get real foggy for diagnosis quickly,... but I think pH issues are at the heart of the matter here, possibly compounded by weak or poorly balanced fert's-? (what are the NPK numbers on the fish goo?)..... Also, your water pH dropping to 4.5 is very weird,.. do you use pH adjusters? and what's the water source, tap, RO/DI? Buffering capacity is in question here,... OF is notoriously acidic, yet you're getting run-off of 7.4, with acidic water going in..?! That would make the soil epically alkaline, to the point of killing them I think, so something if wacko with the pH measuring,...(did you add anything else to the soil besides perlite, like Lime?) I do not trust the run-off method because it's prone to all kinds of measurement errors, IMO.... To untangle this, will be difficult I think, especially if the apparent deficiencies are in conflict with what the pH reading indicate,...
>> the NSR-1st pic: those yellow spots look like early Ca defc. to me,...
>> 2nd NSR- ditto, Mg too,.. maybe others (Fe or S), given the pale coloring top to bottom,.. difficult to say what just yet,...
>> mutie NR- that sure looks line Zn defc. to me,...
>> d-28 bagseed- Hmmm, the dead tips alond edges says K defc., but the leaf and stem colors say P defc.,... not precluding both!
>> ditto for the other bagseed, plus pale new growth looks Fe or S defc.,....
Soooo, between what defc. signs there are, and the water and soil pH's uncertainties,... :slaps: thing is, there's conflicting diagnostics here, and what's behind them,... I'd like Muddy to chime in on what i think i see as well,... hang tight mate, this is a tangled mess! :dunno:

Herp derp. This isn't good! Is there anything that I should attempt to do immediately? Thanks for the help!

 

[Cannabinoid Connoisseur]

Also, I think I was pretty baked last night and mixed the pH numbers up. The reservoir was 7.5 when I came back, and runoff was probably 4.5.

Secondly, the runoff had been sitting for a few days (most likely, I can only guess) in the trays for the pots. I feel like maybe it acidified as the fish emulsion from when I was feeding it got flushed out and degraded.

It might be possible that the runoff was 7.5, maybe that could also be attributed to degrading fish emulsion flushed from the soil?

 

[Albert Eimstoned]

If you're gonna measure runoff it needs to be te very first few ounces and it needs to be done immediately.

 

[Cannabinoid Connoisseur]

Ah, so ignore the pH I reported for the runoff! My water going in (now that I'm back) is between 5.5-6.5 every time I water. That should help alleviate pH related issues. Would still like help for the deficiencies please "uuuuggghhhh.."

Should I start feeding and cal or mag supplements? I have access to molasses and epsoms where I'm located. Getting a hold of some cal/mag isn't feasible right now.

 

[Muddy]

The deficiencies are likely being caused by the pH being off, so before we can make any recommendations we'll need some accurate pH readings, both feed and run off. As Waira noted, OF is notorious for having low pH. If that's the case, then that needs to be addressed first. Anything else, such as adding additional nutrients, won't help and in fact, could make things worse. So lets see some good pH numbers and we'll go from there.

 

[Cannabinoid Connoisseur]

Good news!

I've found (since I'm having to stick with pH drops for now [will get a meter soon]) a better way to get an accurate color comparison between the water color after adding pH test solution with the colors on the pH results picture. If I drop a few drops of the colored water-detection solution mixture on white paper, the color becomes much more clear.

Anyway, got the pH in honed into 6.5. Secondly, I measured runoff at around 6.5 as well.

I think the issue must have been that as the reservoir water sat, settled, and evaporated that the effects of the pH down "wore off" (not using scientific terms, I know, just trying to express and idea). My tap comes out at 8.5+, so I think the water going into the plants was too basic towards the end of my week being away.
