Yeah I flushe
I've been using the MC 2.0 for almost two weeks now and it's looking good. Did some pH testing today just to see what's going on with it and it seems great to me.

With 1.0g/L in RO water the pH came out to 6.0 so that should work fine in my ProMix HP that has added manures, earth worm castings and myco. I was low on RO so mixed some up stronger at 1.5g/L and used half tap with RO. My tap water comes out of a dugout on my property and is pH 8.3 @ 350ppm. With the nutes it was pH 6.5 so that ain't bad. The tap water isn't treated other than to filter it down to 5 micron so there's a fine sediment gets thru and should be chock full of good bacteria etc that will hopefully work well with the dry myco I'm using.

I also added 1g/4L of the Green Leaf Carbo to keep the myco happy.

I'm pretty sure this is the menu for the 2.0 MC isn't it @AquaTerra?

Is that your runoff pH or the nute mix before you add it to the pots?

You can't get an accurate pH from the runoff even if you follow all the right methods which almost nobody does right because they just don't know how. Even if done right it's more an indication rather than a true reading.

I'm going to let the freshly watered plants sit until tomorrow then go down and slowly add some extra water to force some runoff into a clean tray and see what kind of result I get knowing the pH of the nute mix I added today. Still just a ballpark number but a good indication of what the pH is in the rootzone after everything has had time to stabilize.

It sounds like your pH is too high if you really are getting lockouts. To get the pH of the rootzone down you'll need to water in some pH 5 for anything to change. I don't think it's the nutes from my readings today. Swear to Jah you won't kill your plants with some low pH water and it will probably need to be done more than once. Get some good runoff with that to flush the system a bit too.

:peace:[/QUOT

Yeah I flushed with pH of 5.4 and it's gone down from 7..7.2 down to 6.0-6.2. and yes that is the run off that I am testing. And since run off usually tends to be a little higher I don't mind Seeing the 6.2. and the plants are already responding I can see some healthy green at the top of a couple already and I haven't even reintroduced any nutrients yet! Haha

Respectfully. Sometimes we just have to let it go.
Dump the Mega Crop and use what you have had success with.
Always for years have only used Advanced Nutrients 2 Part Sensi Grow and Bloom with some Liquid Karma for Foilar Feed and ALWAYS got amazing results. This is the first grow I have used something different..being Megacrop and I have had nutrient lockout problema

No led. MH veg and HPS for flower all the way. I'm old school..down with LED!
I'll take your word, lol. The way you posted it here and started a thread about it made it seem like a panicked noob. I see you've been doing this a while, sounds like lowering your pH is the way to go. Good luck.​

Thanks for the spreadsheets, easy for me to follow and learn from. Just a thought, pie charts might be useful to visualize proportions?
Any opinions or conclusions on the variations you've been running? I'm around 1.53 ec/760ppm with 2ml CaliMagic, 1gr Epsom and 1gr B Explosion, a few weeks in.

Glad the sheets are of help.
(I started with Lotus 123. Lol)

For Coco....my environment and grow style. Same that you are running. Minus the BE.

Are you using 5gr per gallon of MC?

Calmag.. This is my first run with Zero.Zero cal or mag defs! Why?
Pretty sure..
1. Buffered my coco
2. Used more calmag initially and ramped down week by week.

I use 20% tap. 80%RO.

I need to learn more about proportions.

Why did you drop the BE?
I think I've been around 4gr MC, been measuring by ppm using a mixed concentrate of MC at something like 50gr/gal. Using RO water in 25/75 coco/perlite hempy.

I'm missing something... The MC feed calculator gives 139 ppm/gram, but elemental is 105ppm/gram? Can anyone explain?

Thank you for the last chart!

I know my P at 89 and K at 287 started effing up my leaves with tip and some rust burn. I assume the high P was smoking my chit moreso than the K. Bud it could have been the combination of P and K that cause the burn. So no more of that.

I plan to be much more conservative on bumping the P.

Most of my jacking around is to keep the N down.

Also, @1212ham has a good solid recipe going.

Compare to Jacks.....I need to compare against others too

(The MC+ columns include Mega Crop base, plus calmag, si, and my other crap...)

Sorry if it’s been asked before. But I stored my MC in what I thought was an air tight container. Somehow moisture has set in and left most of my MC a black gooey substance. What u guys think? Can I still use it? Or do I need to order more? I’m using it in soil btw.

I think itd be fine just measure by ppm instead of by weight/scoops. Plenty of people make a concentrated mix with water so I don’t see why not
