Dialing In MEGA CROP for Auto's

[CannabisMingus]

Presumably I will notice if I am overfeeding !

Cheers

Yes. I would keep a very close watch. But even then, you can get root damage before overfeeding symptoms appear. Good luck!

It's risk management. Presumably, you will run eventually auto cultivars that cannot handle such high EC.

The vast majority growing canna would not choose to use that water. I would have been mad if my well water was like that at my old farm. That would have been another thing to take in to account and deal with over time.
My current water, that comes from a commercial well less than 1/2 mile away is pretty good at 160-180ppm. The old farm was 110-120ppm

And you're not really gonna know it unil after harvest and take a good look at the root structure

My water kind of stinks at 250ppm. I can’t imagine it being 500+. That’s not good for drinking.

I'm using mc one part in sip buckets with water pH of 10.2 and ppm of 114...and having all types of issues....I use a ro system and have to use pH down to get correct pH....I was adding 50 ppm of cal-mag to every water...and now my plants look like shit....I started cutting my tap with ro let sit out for 24 hr and add absoric acid and hydroguard....pH it to around 6.7 with 2 ml of pH down...I hope this work

Soil?

Soil?

Yes

How often should I be feeding mc one part and bud explosion??? I've only been feeding once a week....3g mc 1g be 0.5g Epsom salt...and they are. Light green.. should I be feeding more than once a week???? Any help would be nice thanks...

You can't top dress with Megacrop or any other mineral based nutrient, its too concentrated and PH would plummet, and would burn the hell out of the roots! Yes you can top feed with MC you'd just use a little lower ppm. It works to carry an organic grow that's running low on nutrients over the finish line without starving. I've done it several times.

And the plants don't care where it's food comes from because it's all the same by the time it gets to the roots.

Hey pop I'm using mc one part 3g 0.5 Epsom salt 1g be and having yellow leaves and brown spots...I'm trying to figure out how many time a week I should feed...I was using 0.25g of cal-mag too, but people were saying looked like I was over using it... I use ro water....I just need to know what I should do...if you could help I would appreciate it...here's a pic...

Using auto pots and I add .5 epsom to my 1 part MC per gal in RO......those look a lot like my first grow when I didn't know much about water quality and was using well water from a limestone aquifer and adding cal-mag.....I'd go with cal-mag overdose...and I know the net has a big window on the pH ( seen it from 5.8 to 7 in some postings) but I do best in the 6 to 6.5 range.

Yes

What kind of soil ?

From the back yard ? Purchased ? What brand ?

Are you measuring PPMs in ?

Cheers
