Seeds. 21 seeds, 3 strains. Two of which have never been grown on 420 Magazine that I can see. From the original creator/breeder. Been waiting literally months to feel I can be trusted to grow them.
Sadly that time hasn’t yet come
But they’re getting bagged and tagged tonight anyway.

Cool day.
Ph’d up the tank to 5.65 the girls looking happy but very different. Different strains. First pic is a chart. We were running on the red line at low EC as that worked with the Soil Blend of our nutes last time. The OG and GG were OK on it. Not the Skunk 11. We moved to the blue line and saw improvements but not on the Skunk 11.
We accidentally did a “Ph Shock Reverse Shot Nute Swap Smasheroo” to hit the green line. Its even in a little Nitrogen taper where we’re at which is serendipitous to say the least. Cal Mag they get extra anyway.
Look great today. They’re getting a boost of all that stuff lower on the chart they’ve likely been missing the last ten days and we’ll maybe up the Ph a little more tomorrow. As high as maybe 6 then fingers crossed we can just run it stable at 5.8 through to harvest.
Popping/germination is going to wait a night as the blue lab needs a 24 hour soak before first calibration. Its in progress so we’ll pop tomorrow.
Note on the pictures - they are way darker green than the pictures suggest. Almost minty and purple for the OG and GG. Lighter for the Skunk 11’s for sure but that’s to be expected given recent history.

Yup. They look great. Very perky today. An improvement from the last post for sure.Cool day.

I guess you are ph-ing so low cuz you know it’s going to come up. I do the same thing. But I never go below 5.4 and usually it’s 5.5. My understanding is, as you demonstrate here, that below that and they aren’t absorbing the lower nutes any more. Again, apparently we’re in the same page here. So my question for you is, why even go that low? Is it a lazy man thing (I get that, lol)??? Why not go 5.5 and let them eat instead of intentionally cutting off their access to those nutes?Cool day.

It was a mistake to go so low. But one I’ve come to like.
I “crossed the beams” or whatever the Ghostbusters line is.
I reversed my nute balance via Ph as thought there were deficiencies.
So far it looks like a great fluke shot.
But tomorrow may tell a different story and not measured run off yet tonight

To clarify last grow with the “Soil” version same medium put 6.5 in get 5.8 out. No issues. Stopped checking every day. Total luck - that’s what my well water gave out with those nutes. Worked to better than a pound off two plants.
The “Hydro/Coco” blend totally different and been learning it.
Maybe got a grip on it now, 6.3 out off all three. Up a touch and would prefer lower.
They’ll get more the same 5.65 tomorrow. Which will be tested with the new bluelab Ph pen.
Ph is very much my focus at the moment. I think its a fantastic thing to learn if you can play it.
Up and down the Ph scale to tickle different things whilst gas and big EC. That would be a nice skillset to have - I’m on 101 still though.
Lights out flash shot with an indicative colour
Droopy sure but watered and lights been put for 90 minutes nearly.

I'm not sure I'm following all the pH stuff, but I'm curious if this is a buffered or unbuffered medium. Is it mixed with lime or something to moderate pH? If it isn't it seems that sticking with a coco pH of 5.8 (and not measuring runoff pH) would show consistent returns.

Totally - but last grow I put 6.5 in got 5.8 out all grow dead easy. That was Dutch Pro soil blend. This is the Hydro Coco blend and behaves totally differently. This I do need to Ph down it seems. So the last 3 days have been about making up for for some deficiencies because the Ph was too high for a while. Today/tomorrow we’ll go to 5.8 on the nose and and then every day for ever more 5.8
But it was nice learning about being able to influence the uptake of different things by moving up and down the Ph scale.
But stress I can do without next time!
Easy because it was soil, and soil is a buffered medium. It changes the pH of the water you pour in to match its pH.
Totally! Because coco and peat aren't buffered, so the water needs to be pH'd like hydro.
Everything is performing as expected!

It was coco peat both times the nutes were/are the different thing. So the soil nutes buffer themselves to 5.8 in coco peat? It certainly seems to have been the outcome!
Oh, DutchPro soil blend is a nute! Some nutes claim to adjust the pH on their own without adjustment from the user. If that's not what they advertise than DutchPro isn't one of them. Could that blend of nutes just worked better for you than what you're using for this one? What made you decide not to use 6.5 for this grow?

Short answer yes!
I bought a liter of each of A/B Dutch Pro Soil Veg nutes way back in October when I was just a kid with $100 320W light and a 1.2m x 1.2m tent and a dream
3-4 months later things have escalated 
I used that throughout - no flower nutes just another brand booster and calmag. Worked great.But then when it came to buying 20L of each pf A/B Veg and Bloom for 80L I thought may as well get the coco as that’s what we’re in. Treated it the same. It really needs to be at 5.8 on the way in. Which is fine its a few extra minutes adjusting it down. Learnt that now.
If I go back I’d probably buy the soil version again! But I’d did learn a lot for a future issue on potentially being able to play the Ph spectrum rather than just flush and start again.
But I still have 70+ litres not so inclined to change it now and throw the rest. My buddy who uses it on a larger scale has also found it has issues and he heard me bang on about how good the numbers were the first time out. He’s in more coco coir so chunkier than me.
But yeah today when the AC guys finish up with the tents unit I’m going to test the mix. I just Ph’d it up and aiming for 5.8 on the nose through to harvest.

And we’re there.
5.8 in. 5.8 out and 17/18 happy plants.
The one that isn’t is really stunted relative to the rest. My guess is when I can grab a look at rhe label its one that’s root ball hadn’t filled the one gallon like the others. It sort of fell apart where the others were packed and came out the pot smoothly. No matter. We’ll see what we get off her. The runt of the litter can always come good.
Hopefully here ends the adventures in Ph Land for this grow.

You into some kind of Thai Voodoo now Nick? LmaoWow some experiment this is.
I mixed 200L and Ph’d it down. Went for a nap.
Woke up and the ladies had been watered.
Tested. All the same all round.
6.2 and 3.2 EC out. All three strains and states. Consistent. I’m happy with that. Very happy.
Tested the input.
Ph 4.6 and 2.7 EC.
I had planned on adjusting the Ph to 5.4 say when I woke up. But hey. I wanted a change in approach this is some change.
The main thing they might be missing at a Ph like that is Magnesium but they get extra every mix anyway.
Is what it is. I’ll know tomorrow.
Magic bullet or massive error.
For the healthy ones I can’t see a one off hurting them too much. For the yellowing ones I’ll know flush again or not.
It is what it is. Not stressed. Can’t change what happened and having the same out all round to within 0.05 Ph and 0.1 EC is reassuring.
I’ll Ph up the remaining 160L tomorrow to a 6 so they can take a range over the 2 days.

Oops.

It feels like we got hugely lucky. The mega low Ph helped rather than hindered. They’re all shooting up in height. Lights will need to go up again tomorrow.
The OG are really start to flower now 13 days in.

I need to pull all of these Ph adventures together in a single post.
Its a “particular skillset” as Liam Neeson might say but there are myriad deficiencies and excesses that playing scales on the Ph chart I think might fix.
The grey line I have added is where we were at with the OUT on some plants with yellowing issues.
Long story short I think a Phosphorus deficiency. But we zigged from the top right of the chart with loads of N and the normal
Stiff after some flushes and low nutes, ramped up
The feed and zigged down the the bottom left corner. Per the yellow line in picture 2.
Now we are rocking back at 5.8 in and out. All good. Guess we could have flushed again and backed off everything but we played the scales on our way back to optimum.
So flushing wouldn’t have corrected pre existing deficiencies. That would have taken a few days. We Ph shocked to the other end which corrected those and did it quicker whilst retaining growth. That’s the bit I really like.
Be better to not get in a Ph situation in the first place granted! But not every grow can be absolutely identical obviously.
Saturday tomorrow. New Co2 system and more for Hackaday Saturday.
So grey line is where we ended up at one point with 6.5 in on some “bad plants” in the first photo.
Second photo is what we did.
Swooped low to correct some deficiencies without the pain of flush and recovery. We overcompensated some stuff that had been lacking. Then we sprung back to 5.8 perfect. Plants all look great now and we’ll keep them at 5.8 for ever more. But reckon that was as good a fix as you could possibly get. Because flush you still have the deficiencies until they build up over a few days and recover.
The Ph Smash/Switcheroo seems to have bypassed that.
Anyway the ramblings of a crazy man maybe. But it seems to have played out as I hoped. But yeah - in future - I know these nutes need x Ph in different to the originals and I’ll stick to that thank you very much for asking!

Those mornings when you walk to the grow room and its wet outside it…
Irrigation manager left a ring tap on and the main supply from the tank on.
100L of nute mix out on the floor overnight.
Happy Saturday!
Meh.
Today have the Co2 system being moved downstairs. For the solenoid it needs a bit of power jiggery pokery and the delivery pipe needs running.
The guy should come to measure up for the tent AC hood/splitter too.
Also last night I ordered 21 new drip trays with integral drainage. The ones on wheels are actually a PITA. Plus as they’re circular they’re not actually very efficient so get evenly under the lights - the new ones are square and I’m going to have a drain put in the room to outside. No more floods but will also be able to run a full flush on any plant in situ.
The main problem with the circular ones is the drip trays are too small and too fiddly to get back in with limited space. If they had rails along the full length of the tray space they would be so much better. Still for defoliating and inspection they’re still useful to have.
Think there’s something else going on - maybe just the Co2 delivery. Graduating to delivery and collect service would be great,
Not sure if this is a one off though. Bet they’ve got one of those truck things Azi was recommending
The sun is shining and my plants are happy. Even the runt has perked up over night.
