Oldsmokey Grows Blue Cheese & Blueberry With Promix

[The Celt]

I realize that the pH of the nutes doesn’t change the pH of the medium, but I was looking at it from the chemistry stand point. When pH rises, you have an excess of OH ions (above 7) and an excess of H ions takes the pH down. Vinegar being a non nute, essentially a neutral component as far as nutrients go, is just providing the excess H ions that the medium is lacking, if that makes sense.

I dunno nuttin' 'bout the chemistry of it, but if lowering the pH of the substrate were as easy as pouring vinegar through it, I'm sure that would have been mentioned to me by the manufacturer of ProMix!

I did adjust my pH to 6.1 last feed first time this grow I have adjusted it. My thinking is simple it can't hurt.

Vinegar is a carbon source. If you have active bacterial growth in your media, the vinegar is rapidly biodegraded, and won’t keep pH in check

Holy shhhheeeet! Is that a marlin? Big beautiful fish, I would feel obligated to take that sucker in to the taxidermist and mount it on my wall! Wow, I’m so jealous of the fishing you guys get to enjoy haha

Actually a Pacific Sailfish.

I might of spoken a bit to soon. Today I am noticing on one of the Blueberry some new rust spots closer to the bud. On both Blue Cheese the tip of the leaf margins rust or burnt on some of the fan Leafs.

I might of had the light a bit to close raised now. Besides that I am seeing good growth. And today was the first time I open the door and there's the smell I have been waiting for. Sweet skunky smell puts a smile on my face everytime.

That's all for now I will do an official up date in a few days.

Have a great night!

Hey Smokey! Everything is looking great and congrats on the new title and Mega light! Have you tried flushing the plants to see if it helps? Possibly a salt buildup causing the calcium lockout? Stay safe and medicated!

If I didn’t pH, the MC only brings my tap water to about 6.9, while distilled water gets closer to 6 which is fine.
It may (or may not) be true in many cases that it doesn’t need to be pH’d, but in my case I feel like the plants aren’t getting all they need if I didn’t. We have hard ass private well water too so I’m sure it’s much different in RO.

 

[TastyTerps]

You're welcome.

I put MC on hold for a little bit, and went back to gh trio. We’ll know in a few weeks if it pays off or not. I flipped a single girl last week, and about 3-4 weeks from flip is when my cal/mg issue was showing up with MC.

If this is successful, I’ll give MC a shot on some autos next month in the rdwc.

I hear this a lot from other MC growers who begin experiencing similar issues near mid flower. I personally use the manufacturer dosage recommendation and adjust it based on the color of the leaves, which is also what they recommend. When I saw the same issue during mid flower, a good flush and fresh dose fixed my problem. I can’t say definitively, but I think the issue is caused by salt buildup in the medium causing the lockout. It won’t hurt to try flushing and then resuming the normal feed schedule.

Thanks Tasty no Mega lite with the MOTM that would of been nice. I did a flush 3 days ago ran 20 gallons of water through each plant followed by 2 gallons of nutes 4.5gm/MC 4ml cal mag per gallon oh adjusted to 6.1. I also water to run off 10- 20% to try and prevent buildup.

It was kind of a experiment for me not adjusting ph. I learned to grow in hydro so not adjusting the pH was hard for me to do after 30+ years of treating pH like gospel.

Sure, but that doesn’t explain it in hydro. I don’t play in the dirt. (Not because I don’t like it, I just don’t like having to haul it in and out and blah blah. Water on the other hand, I can pump that in and out. )


It’s weird thing for sure. I think maybe Shed is onto something with the different nitrogen parts, and one form (the main one in MC) causing pH to rise and become unstable.

It isn’t a following directions thing, guarantee that. What I also do is read the leaves. They tell me they are unhappy, and it’s obvious. Why they are unhappy (root cause of the issue, not a symptom) is the million dollar question.

I can say that trio isn’t acting like that, but at 5+times the cost of MC, well, it sure would be nice to run it if I could.

But I’m not pulling out soil or promix just to use MC.

Intense led lighting and high doses of nutrients probably plays a lot into it, I would think. Coupled with the fact most of us are running this type of stuff without any CO₂ probably doesn't help. We're not running simple grows, a lot of us are using gear/nutrients for high connoisseur grade bud, throw off one thing (vpd, nutes, lighting, CO₂) just a bit and a domino effect happens since everything is being ran at optimum performance.

Like running a top fuel dragster, one loose bolt can be catastrophic.

Good morning all
Yesterday was feed day also day 43 of flower so what i decided to do with the issues I have been having the last few weeks. It's looking like M/C nitrogen level witch ls almost totally nitrate is raising the pH of the medium. I wasn't able to find a substitute nute with more balanced types of nitrogen. There online but can't get delivered or out of stock. The garden centers around here are slim pickings as the season is almost over here.

I used a 3 part bottled nute that I have on hand and have used for years although mostly in hydro. So I fed 5ml part2 whitch is the nitrogen and 5ml part3 bloom nutes and 1ml cal mag per Lt of water. I also adjusted the pH to 5.8. those are base nutes I do have a few other additives but am holding off. That is the manufacturer's suggested dosage.

Things really don't look that good growth has really slowed most pistils are red or brown. This is the time where the buds should be packing on the weight and there not. There still drinking about 6lt every 3 days. So I am getting the feeling I am just riding the rest of this grow out with low expectations. At the same time thinking of the next grow and what to do. I will post a video to night to try and give a better pic of whats going on.

Have a great day!

Sorry to hear that smokey.

I'm finding that every grow I learn something new, so I like your attitude! I hope you're pleasantly surprised come harvest time though.

 

[oldsmokey]

Thanks shed it's a bit strange since last grow only difference is the strains. Last grow was awsome even had one plant over a pound. Hopefully I get surprised by harvest. That's growing there not all bumper crops. I am contemplating going back to hydro to be able to deal with the pH better.

 

[InTheShed]

Hydro does give you that advantage.

My Power Plant and my Chocolope have the same increase in pH, but only the PP seems to be suffering, so obviously strain will make a difference.

 

[THC Onlyfans]

Plants are looking mint! Delayed congrats in the motm!
Liking the discussion on MC, but doesnt seem like many have figured out. I've been experiencing problems during mid flower also with MC and BE. Will be following to see if anyone has answers.

 

[oldsmokey]

Thanks THC wish I had some answers for you.

 

[Dusted]

The GH flora series contains nitrate and ammonium salts for N. If the straight nitrate is giving you problems with the pH rising perhaps try GH which caused my pH to drop instead of increasing

 

[oldsmokey]

I could go to the hydro store and they would have lots of nutrients to sell me with all the additives. I am trying to get away from that. At this point in the grow not much time left and I am not expecting a big recovery I hope I am wrong. I am thinking more about how to proceed with the next grow. I am thinking of going back to hydro that's how I learnt to grow. Much easier to control everything. Or there is also Geoflora nutes look interesting.
