Dialing In MEGA CROP for Auto's

Still had some issues this last grow but came out with some decent buds.

I have a new experiment started with 4 Airpots with different mixes.
2/3 Pro-mix, 1/3 perlite
1/3 each pro-mix, perlite, and organic soil
2/3 Coco, 1/3 perlite
1/3 each Coco, perlite, and organic soil.
Going back to basics with MC only with progressive ramp up and flush just prior to transition to flower. Seeing @chuckeye ’s results with high MC doses has me second guessing my previous assumptions.
Should be interesting…

I was following the feeding schedule on Greenleafs web site ! Enter the amount of water and it calculates the grams of MC for each stage of growth.

About half way through flowering I did one watering without nutrients and almost immediately the fan leaves started yellowing.

That leads me to believe I was feeding at "just enough" and missing one feeding had negative effects ?

Thanks for the rep @Nosias and @>Potato

@chuckeye i know you’re feeding at their recommended doses. But looking through these threads and other peoples experiences, generally it seems people are running lower then the recommended. That and the general assumption that auto’s don’t like anything higher than ~600ppm.
In my experience, I would run into tip burn when I increase, or issues if I decrease or included other additives. Don’t know if some of that may be due to buildup which is why I’ll be flushing at the transition.
I don’t think I’ve just stick to the recommended so I figured it’s experiment time.

On the other hand, I've read others using more and in earlier stages of growth !

This Gorilla Glue #4 was wet trimmed yesterday. Last four watering's I fed 6g MC and 1g of BE in 4L of water twice and 7g of MC in 4L of water twice.

Well water with a ppm of ~500, un-phed. Ph is ~7.5. Last time I checked 6.5g/4L gave me a ppm of 1050.
