And not enough for some. I had a deficiency on one plant while feeding it 7.0. glad things are looking up for u.

What's the most MC per gallon you've heard of anyone feeding ? Just wondering because the bag says 6.5 grams all the way through flower.
Not use to having these types of issues. Usually just get some N def. & not much else. Maybe a CalMag issue near the end sometimes .... but never had an N toxicity before.
I haven't decided whether or not I like MC or not yet. I like the simplicity of mixing for sure.
But I don't like the pH stuff associated with it. After mixing it I get a 6.6 pH. Everyone says not to pH MC. I would normally pH to 6.4 with other nutes. Then pH run off is way different in all 3 plants (5.6 / 6.5 / 7.5). I'm told that doesn't matter with MC. Normally I'd make sure run off stayed between 6.0 - 6.6. I'm kind of a control freak in my grow area so not having control of these things is driving me nuts. So this part of using MC I do not like.
I'll try it for another grow or 2 to see if I can get use to it. Might be OK once I dial it in.

This is the problem with MC... over application can cause lockouts that appear to the inexperienced to be deficiencies. Running this stuff is a balancing act and many things go into the calculation as to how much MC a particular plant can take. Soil growers seem to need less than hydro growers too, so things are very confusing out here right now trying to figure out how to use this stuff. Vulx also changes the calculation.
It is very possible to grow with MC and not have any die off or fading right up to the end. If you get to mid or late flower and are having many dead or necrotic leaves, something wasn't right in the nutrition department and it may be instructive to go back to the basics and review the instructions GLN gives about fine tuning the dosage of MC. Increase in small increments and if you see any damage, decrease the dosage. My observation is that MC does not produce deficiencies... there is just too much stuff coming in at the plants to allow this. MC does produce lockouts that look like deficiencies. It is a total mind flip.

Hope you get this fixed buddy. I’m not experienced with soil/mc. I’ve only grown in promix. I check runoff ec to check for lockout, hungry plant, salt build up but with synthetic nutes that’s a lot easier. I’m not sure how it works with MC. Can’t go wrong with a quick flush to remove excess salts and nutes though. I always flush when I switch to 12/12

Thanks for stopping in & checking things out. I think it's going to take a few grows to figure this stuff out. Going to get more confusing next grow since it will be in Auto Pots, Coco & adding Bud Explosion & Sweet Candy. I better start studying for it now. Also going to be SCROG style so it should be interesting.

It’s all a learning exp that never ends. I think you’ll do better in coco as it’s “mostly” inert. I’ll be switching to coco for my tangerine dream/critical purple grow soon. Coco allows you to fix deficiencies a lot quicker than soil but they show up quicker too.

Check out npk university/npk industries on YouTube. Dude with lamb chops has a few 40min videos that are def worth watching.

I’m a huge fan of scrog. I always scrog mine out. Except for the autos I’m growing. Word of wisdom get a 1gal garden sprayer for watering when you do Once the nets up it can be a pain to water. Lol

Megacrop would be a good choice for coco. Keep it as simple as possible.

Auto Pots so only have to fill the res. Still have to be able to tuck branches though.

This morning the Afghan looks way better. Most of the hook leaves are either going away or just less noticeable. GG hasn't changed a lot yet. Doesn't seem quite as bad.
Anyway, my grow room is coming along. All walls are up & ready for the Mylar. I ordered a Roll of Vivosun 6 ml. Diamond Mylar with Poly backing to cover the walls with. Should get that next week.
Within 2 - 3 weeks I think I'll be done .... at least I hope so. Well, can't actually finish till these plants are done as I need some of the equipment from this grow. But close enough.
Unfortunately, the 1st grow in there will be during the hottest part of the year.

 

[Black Thumbs]

I’m sure you will get on top of what’s going on.Looks like a N tox so maybe your mix is just holding on to what’s not being used so hopefully now it’s been flushed and dropped back a bit on nute level it will pull through it
my in-laws smartpot setup under a net using MC is doing amazing and this is his first time using MC and only second grow so I’m sure you will crush it

 

[Pennywise]

You’re getting closer, will be sweet when it’s done.

 

[Buds Buddy]

Went & bought the trim for my grow room today. Should have the ceiling up & trimmed out by time the Mylar gets here. Getting Real Close.

Take your time and do it right.

Any idea why the run off pH would be so high in the Afghan, but normal in the Gorilla Glue? Same Soil / Same Nutes.

Measuring the pH of runoff isn't a thing in any medium. Can't tell you why, I just know it doesn't tell you how to fix anything that might be wrong. Only a slurry test does that.

As far as I know these are all Indica's. At least I hope so as they were advertised as such.

That Gorilla Girl looks like it's flowering like a sativa though, with the long flower spacing.

Runoff ph tells you very little.

This ^ !

anything below 6 grams in full flower is too low.

I think it's more a plant by plant thing than a specific rule. I just bumped my flowering plants to 5.0 and they look great about 5 weeks since flip.

Just wondering because the bag says 6.5 grams all the way through flower.

I thought the bag says 6.0, not that it's as important as reading the plants.

 

[Pennywise]

if you’re using tap water the calcium and magnesium is probably raising ph of your medium. But it doesn’t affect the roots ability to take up nutes. We just concentrate on what’s going in.

The GG & Gorilla Girl are actually labeled as Indica Dominant Hybrids. I think they are more of a 60/40 split. Don't know why I'm even growing those 2 strains as they are OK but not as potent as I like my weed. Not sure how the Afghan is yet as I haven't grown it. I started 1 last grow but got freaked out over a caller. I bought a Co2 set up during that grow off of Craigslist. I met the guy at a gas station & right away he started telling me about his big grow operation & how he supplied some stuff to dispensaries, etc... Then he calls me a day or 2 later asking me to sell him a pound. I shut down my grow 5 minutes later over that. Why would someone with a huge grow facility ask me to sell them a pound ... right ??? Scared the hell out of me so I was down for about 6 months over that.

Should I be checking for a 6.4 pH going in ? I haven't even been doing that as I was told it isn't necessary with MC. The pH is only 6.6 after mixing anyway so not that far off.

What’s your starting water ph?
Mine is 7.2 and with 5g a gal it’s down to 5.9
And yea that Craig’s list stuff would have freaked me out as well

 

[Buds Buddy]

Mine usually reads around 7.5 out of the Tap. One day I got a reading of 8.7 after filling 3 gallons.
I have no idea why. All 3 gallons said 8.7. That's only happened 1 time in 3 years of growing so not sure what to think of it. I'm wondering if the water company added stuff to the water that day or something causing it. Next day water was normal again.

Are there any step by step instructions on calibrating a pH pen on this site? I have several pens. I just use them till they don't act right & then buy a new one. I think it may be time to buy another.

Anyway, woke up this morning with GG begging for water. She looked fine last night. Woke up & leaves were hanging limp. Fed her & she's already perking up. I went all the way back to 5 grams per gallon from 6. I'd rather the plants tell me they need more than need less. The other 2 pots are still heavy so they don't need anything yet.

 

[MrSauga]

Most pens come with instructions on how to calibrate them. Typically you need a high(7.0) and low(4.0) buffer solution.
You also use this solution to store the pens so the tips don't dry out. Sitting in water is a no-no.
