Nutrients Prescription Blend Grows SweetSeeds in AutoPots - Test by Only1Sky

[Only1Sky]

Updates on the two Killer Kush plants. Got a new pH pen. So I've now compiled numbers for the last two feedings. I'm not savvy with these analytics, but it seems to me like the Greenleaf numbers are kinda out of whack. ?? Good news is, for whatever reason, the problems with "interveinal chlorosis with necrotic spots" has virtually abated on both plants, and both seem quite healthy at the moment.

Prescription Blend Plant
Mar 15: 3.0 liters in, .4 out = 13% runoff; PPM 753 in, 216 out; pH 6.14 in, 6.47 out
Mar 17: 3.5 liters in, .45 out = 12.8 % runoff; PPM 751 in, 242 out; pH 6.67 in, 6.69 out

GreenLeaf Plant
Mar 15: 3.0 liters in, .25 out = 8% runoff; PPM 175 in, 538 out; pH 5.10 in, 7.52 out
Mar 17: 3.0 liters in, .20 out = 6.6% runoff; PPM 161 in, 539 out; pH 5.36 in, 8.22 out

Shifting over to the 4 Sweet Seed Plants in the Autopots. Happy to say that all are doing quite well. Here's some photos taken this past weekend - all of the plants were at day 57. First a look at the two Prescription Blend plants; Trainwreck on left and Jack 47 on right.

A closer look at PB Trainwreck:

And now a closer look at PB Jack 47:

I'm very pleased with these two plants, and especially love that the AutoPot lines and valves remain clear and flowing.
Now lets shift over the the Greenleaf plants, which I've taken out of the tent for purposes of this photo shoot.
Trainwreck on left and Jack 47 on right; Two views from slightly different angle.

Now a closer look at GreenLeaf's Trainwreck:

And lastly, Greenleaf Jack 47:

The plants are good. But the Greenleaf mix in the AutoPot systems has been a disaster. I continue to get clogs. This week I had two days in a row with the valves and lines of both plants needing significant time to disassemble and clean. ug. That's it. I tried this nutrient programs now 3 or 4 grows with AutoPots. Never again.

.... Sky, I know your stoned, but not THAT stoned! Those ppm's on the MC, am I seeing rightly here? ...the feed was only 175/161 going in, 500's+ going out? I'm just checking on the input values that are only in the 100's.... not turned around are they?
Even more baffling are the pH values, that is wack-a-do to see that amount of alkalinity- that simply does not compute! That's 3 orders of magnitude (1000x) jump between 5 and 8,... ...no, no this is a total enigma...If the rough calculations for run-off pH measurement are applied, the in-pot pH would be like lye solution! There'd be little mushroom clouds where the plants were-
Your PB values all look fine to me, notable is how the run-off is so low in ppm, and also, a slight rise in alkalinity... More often, it drop's in pH...
That said, if the meters are in calibration (and it would seem they are, or the PB numbers would be wack too), I'm at a loss to explain this.... Let's consult with @Prescription Blend

The girls look great Sky- I love Sweet!.... confirm what my eye's see in the pics: PB TW is less ripe than the MC TW, and the PB J47 more ripe than the MC one? This seems more likely a pheno' thing...
Would you say the bud:leaf ratio is generally better on the PB plants vs. MC, or about the same?

Well, Yep, I too Love Sweet Seeds, so many great choices in their Autoflower catalog. Your eyes are sharp. The PB TW is at least a week, maybe 10 days, "less ripe" than the MC TW. And, yes the reverse is true when it comes to the PB and MC Jack 47 plants. Bud:Leaf ratio is denser on the PB Jack, whereas the MC Jack is taller and with more space between everything. The two Trainwrecks are fairly equivalent in terms of structure.

Now, as for numbers. I actually wasn't stoned at all, although these numbers are giving me a thorough lapidation. And, just for further head scratching, I did a feed with measurements yesterday. I have added it as the third row in this on-going saga:

Prescription Blend Plant (Killer Kush in 3-gallon RainScience Grow Bag)
Mar 15: 3.0 liters in, .4 out = 13% runoff; PPM 753 in, 216 out; pH 6.14 in, 6.47 out
Mar 17: 3.5 liters in, .45 out = 12.8 % runoff; PPM 751 in, 242 out; pH 6.67 in, 6.69 out
Mar 19: 3.5 liters in, .4 out = 11.4% runoff; PPM 913 in, 230 out; pH 6.37 in, 6.61 out

GreenLeaf Plant (Killer Kush in 3-gallon RainScience Grow Bag)
Mar 15: 3.0 liters in, .25 out = 8% runoff; PPM 175 in, 538 out; pH 5.10 in, 7.52 out
Mar 17: 3.0 liters in, .20 out = 6.6% runoff; PPM 161 in, 539 out; pH 5.36 in, 8.22 out
Mar 19: 3.5 liters in, .65 out = 18.5% runoff; PPM 143 in, 460 out; pH 5.64 in, 8.06 out

And just for further info, I took a few soil pH readings today: PB was 6.6 and MC was 6.7. This is very consistent with previous PB readings:
Feb 13; PB soil pH 6.65
Mar 9; PB soil pH 6.53

I had not previously done a soil pH reading for the MC plant, so today's number is the first, but it seems quite "normal" to me.

maybe a couple sharp blows to my blunt skull would knock a clue loose!
OK, first thing I have to ask: why is the MC feed input so lowin ppm? Are you using volume or weight for measuring out the MC? And just to be sure, there's not a little 10x showing/flashing when you test? Some TDS meters have only 3 digits readouts, so if the ppm's go over 1000, it drops a decimal and shows 10x to the ppm reading. It's the only thing I can come up with, no way the coco and plant are releasing that amount of ion "traffic" into the coco's run-off soln. with such low input values,.... And I'm pretty sure you're not defying the universal law that says you can't create something outta nothing! *(maaaybeee,.... Satan??!) a little Dana Carvey's Church Lady routine form Saturday Night Live-- sorry!
It would account for the high run-off ppm, proportionate more or less to the ppm drop in the PB plant,.. That in general is a bit mystifying, that those readings are much lower than inputs,.. unless the plants are just eating the heck out of what's in there!
... or you're fuckin' with me and are now on the carpet rolling and gasping for air?!

@Waira - well gosh by golly, what dah yah know? There is a flashing indicator on my PPM pen. Once I pressed a "hold" button I could see it plain and clear when I remove the pen from the solution. All hail Waira, you have solved the riddle.

So the real PPM numbers for input vs runoff for the Killer Kush Greenleaf/MegaCrop plant are:

Mar 15: PPM 1,750 in, 538 out
Mar 17: PPM 1,610 in, 539 out
Mar 19: PPM 1,430 in, 460 out
In my defense (though there really is none), this is my first time using a PPM pen. However, I can clearly hear my Father's voice; "Son, don't go near that wheel-barrow, you know you don''t know nuthin' about machinery."

Sorry to put you through such challenging mental gymnastics. Think I need to go sit in the dunce corner for a while.

Wow those are high ppms for MC! Lovely plants, though.

.... ahhh, that's what e-friends are for! .... I know, I know, here's your brown eye winking at me =

OK, with my breath back now,... ... ... I'm a bit shocked that the MC plants don't look cooked with those ppm's,... A possible explanation:
I have speculated that because there's so much stuff in there that's ionic, non-ionic, in-between (neutral in net charge but with significant charge polarity) that the actual base nutrient content relative to the ppm isn't as high as one would typically interpret... Si, amino's, humic-fulvic, kelp bits(?), sugars, etc, some of which will register directly on the meter, other not so much but may affect things indirectly... Consider sugar, which is neutral in charge and not very polar either; this isn't a salt, sugar crystals dissolve into individual molecules, but remain otherwise intact... A salt of course breaks apart into component ions with charges. I'll have to test it out, but sugars shouldn't register, but amino's may, Si for sure, humic-fulvic maybe weakly,..... Point is that 1700+ppm of some other nute would probably fritter things!
In any case, I'd ease those numbers down some, many MC users are running half to a third of that, and see what the run-off drops to... Clearly she's eating well to drop them so much! Any sign of tip burn Sky? This strain certainly has passed the heavy feeds test!

:smoking: How they doin'? @Only1Sky

I'd love to hear a nose-report! I have the F1FV J47, and am giving her a hard look to run this season... Torn between her and Strawberry Amnesia (for my Haze fix)!

Sweet Seeds KILLER KUSH Update (full photos in next post):

@Waira

Yep, there is a tiny bit of tip burn of both the MegaCrop and Rx-Blend plants. No big deal though.

I'd love to hear a nose-report!

At 69 days the smell is distinctive, but not overpowering. Its sweet, a bit citric, and definitely a bit diesel fuel. Both plants smell the same.

The interveinal chlorosis with necrotic spots seen previously on both plants abated dramatically. The only major change on my part being: 1) always mixing the feed in the proper sequence, and, 2) increasing the runoff is 12-15%. The symptoms still occasionally appear on both plants, but its minor and not really a worry for me. Here's an example: Prescription Blend leaf first, then MegaCrop (Greenleaf) leaf:
