I mixed up 5 gallons of 2 part MegaCrop to try and match the KISS mix from above. I ended up at 3g/gal of A and 2g/gal of B which was:
(N) 121
(P) 46
(K) 172
(Ca)100
(Mg) 49
(S) 65
(Fe) 2
(B) .3
(Mn) .5
(Zn) .8
(Mo) .09
(Cu) .3
(Si) 1

Total 561

I ended up coming down slightly from this. I am in perlite and not coco. I ended up with some minor browning on the tips of the older growth. Nothing major by any means. Right now I mix 5 gallons of RO at 2.5g/gal of A and 2.5g/gal of B and then add another gallon of RO to move the EC down to 1.4. Seems to be working well for the last week or so. Thanks for getting me close, to begin with.:-D

Now that you know you need that extra gal....Can you just start with 6gallons of RO?

Thats what I do, eliminates most of the need to dilute with RO. (Some suggest best to dilute with calmag water not ro)

I figured adding a gallon would be a 20% dilution so with that I guess I could cut the grams per gallon by 10% each part and that would be close to the same EC at the end. I should just try it out and see what's what.

Similar.
After mixing, would always have to use a little ph UP to set my final PH.

Now, first thing I add extra (approx .75 ml per gallon for my mix) silica to RO, then after mixing everything as usual, ph is near perfect every time. No need to PH up.

Unique to MC 2PartA it contains.....

"Amino Acids and Amino Acid Chelates"
How many ppm, no idea.

Also they brag about silica.
Only one (1) ppm @ 5grams of MC. Rip.

No biggie, just true.
I would use MC2Part but I get jacks local and cheap.
