Lighting AutoCob, Auto Flower, megacrop thread.

I have not used so much as 1 drop of cal/mag with the new Mega. its just not needed. But of course, there is always the occassional cal/mag hog strain lol! I've not seen one myself though.

Yes I’m using the 2.0 as well. It’s the calmag 2.0 that’s got the extra nitrogen that’s to high in my opinion. I didn’t read the labels on the new calmag and added it like normal. Plants turned dark green in 24 hours, 30 hours tips dropped and 48 hours weren’t happy at all. I ended up ruining the crop. It’s nothing against them, it’s on me for not reading the bag. If used in moderation with a decrease in megacrop it should do well. Some say they don’t even use calmag with the 2.0 megacrop. I’m learning.

I use MC 1.0 with CalMag supplementation around 1/4 of total ppm, and nothing else except pH up/dn, from start to finish.
The plants look great, and yield big.
When I run out of MC 1.0, I'll probably cut out the CalMag.

My opinion is that we should believe Greenleaf when they say MC is all that's needed.

I agree with pop22's moderate ppm from early veg to finish. I keep mine around 450.
