@terp182 so I'm no expert but if your in flower your mega crop dose if by itself should be like 700ppms/900ppms [depending on the scale your ppm meter uses] or around 1.4 ec I would suggest a bit more mega crop if thats all your using. She doesn't just brown spots she looks a bit pale like not enough N just my two cents but I'm still learning.
Dialing In MEGA CROP for Auto's

Pretty sure this was the cause. Since the other plant looked fine, on a hunch I decided to swap out the pot itself. And lo and behold, the bottom was super sedeminty and stinky. Not sure what happened here, if it’s runoff from the first couple waterings and Recharge extras hanging out, but I’m glad I switched it out!

That's good you hopefully found the problem. I tagged pops but i think he's travelling right now.. so hope that takes care of it for you
This is my first time using MegaCrop. 14 days old 420 Fast Buds Blue Dream Matic in 3.9 gal Autopot with soil/Perlite. The plan is to stick to pop22s stay around 500 ppm 6.5 ph all the way thru plan.
some questions for @pop22 @GeorgeCloney and @4d-Rock :
Like @4d-Rock I'm using ProMix HP with MC. I personally have a ton of MC v2 and like 4d-Rock, I run into issues every single f'ing grow early into flowering. My leaves turn yellow and start to show brown spots as time goes on to the point where the leaves look like they're decaying. In fact, the pictures of issues that 4d-Rock has shown with their grows could be photo-copies of my grows, the similarities are so exact.
Now for the questions;
with ProMix HP, what PH are we targeting. Read this whole bloody thread and I'm still not 100% clear what PH zone I should be aiming for. Some posts say 5.8 - 6.2, some say 6.0 - 6.4. which is it? I've been told specifically to use 6.2 with ProMix.
I HATE quitting, so I would REALLY like to be able to master MC with ProMix HP before I bail and switch to another medium. I don't see any reason why I wouldn't be able to master this but I'm beginning to think that they're not a great paring with each other.
All that being said, according to suggestions early on when I started using ProMix, I've been going with the PH 6.5 range with MC and ProMix HP, swinging between 6.2 and 6.5. My current grow, while very green and healthy during veg, has yet again gone to shit during flower. So I've started adjusting the PH to about 5.9ish as the run off water is now showing 6.0 to 6.4 PH.
It's only been about 4 or 5 days of lowering the PH, but for all I know, I'm doing it wrong, 'cause I believe I'm still seeing further yellowing of the leaves, just like 4d-rock has.
Next question is for IF and WHEN I decide to switch from ProMix HP to soil. ( I have maybe another grow or two left of ProMix in my bin)
For those of you using "soil" what are you specifically talking about? The word soil has been used to describe so many mediums now, I have no bloody clue what anyone means anymore. I think I even read a post in this thread from @GeorgeCloney use the term "soil" with (peat and coco) in brackets. If I'm not mistaken, isn't that a "soilless"?
Reason I'm asking about the soil is because after I mix my MC with my tap water (20-30ppm at about 7.6 PH), the solution stabilizes long term at 6.4-6.5, give or take a point either direction as PH swings occur with city water.
So if I could just use a true "soil" instead of a soilless, I won't have to dick around with PHing or deal with the runoff. My real confusion is, real soils are rich in nutrients and microbial life already, so by using a soil and then using MC right from seedling, as both @pop22 and @GeorgeCloney have mentioned they do, wouldn't that be too hot? wouldn't a rich soil + the use of MC so early just kill the plant?
Where I live, I have access to all sorts of stuff. so I guess I'm trying to figure out what this "soil" is everyone's talking about. Like what is it? Surely not potting mix? I live in BC Canada, so we have A TON of "soil" options here. Living soils, compost soils, flower bed soil, top soil, potting mix soil....
If I wanted to switch to soil while also using megacrop, what the hell am I looking for in a soil? For example, there's even this stuff I can readily purchase, https://www.reindeersnatural.ca/Brown_Gold.htm says it can feed plants for up to 4 to 6 months. I imagine if I used this stuff with MC, I'd burn the plants to death in a couple weeks.
So what is "soil"? lol. What kind of soil should I be looking for when using MC right from seedling all through to harvest?
In my mind, if you guys are using actual "soil" as well as MC right from seedling without burning your plants, your soil must be pretty inert? Or?
Thanks for taking the time to read my confusions, lol!

I'm trying out an organic soil mix from Cinnabar Farms here on Vancouver Island. ProMix HP had me banging me head on the wall most of the winter. In February, started one plant in a 1 gallon pot of Cinnabar's My Soil, and fed MC starting at 300ppm and going up to 500ppm range. I was good with the results, and am using that mix with some additional amendments outdoors this summer. It is frustrating, watching the plants cruising along until early stretch, then the grow goes south. I've watched Pop22, F.N. and a couple others who seem to have MC dialed in. So I know it can be done.
My experience MC is with soil but I sugest beacuse your using peat, your requiements will be different. I'd go with 6.2 - 6.3 for PH. You may need to run higher ppms in flower than I do in soil. Soil holds nutrients better than other mediums, thus the need for lower ppms. I'd up them in flower to 600-650 and see if that fixes the issues, I think your plants are just hungery, which acount for both the yellowing and the spotting.
As to using soil, I use organic potting soil, Specifically Lambert's, I've used Roots Organics also. Not a fan of Roots, I ans everal others have had issues with bugs in the soil, including root aphids and white flies. But use what you can get. I run my PH at 6.4 and I'm pretty strict with my PH. I accept
6.39 - 6.47. If your pen only does single poin then keep it at 6.4. I rum 500 ppms in veg and recently upped ppms to 550 in flower and have good success

YOU'RE ON THE ISLAND TOO?!?! Nice! I'm in Langford. Been eyeing up Reindeer Natural's (located in Cowichan) "Brown Gold" or their "Easy Bake" products because I've been struggling with ProMix for so long, especially when, like you, I see folks like Pop22 just cruising along with no issues. Drives me to become obsessive while trying to figure this ProMix / MC combination.
You haven't noticed any nute burn issues using a rich organic soil with MC right from the start?

Thanks Pop22! the ability to hold onto nutrients isn't something I considered. I'll up it to 600 for a week and see what happens.
With regards to the soil you're using. Were/are you not concerned with the soil already having enough nutrients that adding MC from the start is pushing the plants too hard in the beginning, at least during veg?

Errington here.. most folks don't know where that is.. maybe 5 minutes from Goats on the Roof.. Cinnabar Farms is in Nanaimo and I picked the bags up at Station feed and supply in Errington, as Cinnabar is only wholesale. This is my second summer on the island and only grew outdoors before moving here. Outdoors is a challenge for photos in our weather, so I'm on a new learning curve with outdoors as well.
Cheers neighbor
