I have a question about the below mix. I am shooting for the KISS method with the Greenleaf products and was wondering about your opinion. My goal is to use the same base mix for veg and then add the BudExplosion for Flower.

My question is does the 2 part mix ratio look a little low on nitrogen for a vegetative growth ppm ratio?

MC2P /// BE
(N) 121 ///
(P) 46 /// 23
(K) 129 /// 90
(Ca)113 ///
(Mg) 37 /// 2.5
(S) 49 /// 26
(Fe) 1.75///
(B) .2///
(Mn) .4///
(Zn) .6///
(Mo) .07///
(Cu) 2///
(Si) .9///

Total 490 /// 631
EC 1.4 /// 1.6
Ridiculous formating sorry

Srry for delay, just read it.

I calculated the NPK % ratio for the above ppm as...
1.2 - 1 - 1.5

Still in the process of learning about ratios and ppms levels.

Are you talking about the MC1Part or MC2Part?
How many grams per gallon?

Your N seems good for veg.


Here are the 2.25/2.25 numbers from their calculator, today.
If using this, I might add 1 gram Epsom per gallon to bump up the Mg. (+26) to half the Ca ppm.

When it comes to the BExplosion stuff, be careful. Know you numbers to prevent excess P and or K. Especially K in coco.



FLOWER ppm example - as per Jacks Feed Chart.
PPM comparison - Jacks bagged 10-30-20 flower formula is a 1-3-2 NPK % ratio.

elemental PPM for NPK % ratio of 1-3-2....
N 100
P 132
K 168

Higher EC, still 1-3-2 ratio.
N 150
P 198
K 252

With the MC Part-A and Jacks Part-A mixes being virtually identical, Jacks users can learn from the simple GLN feed chart.
Adjust the A/B to change the NPK ratio for the 3 different phases, rather than running just 3/2/1 start to chop.

Thanks for the information.

I do have some Epsons ready to go in case I see the need. In this perlite Mg looks good for the past couple weeks. On the BudExplosion note I have been adding just 1 gram to a gallon. I am in the middle of week three and have been feeding the BE for a couple of weeks. Here's a close leaf shot from this morning on one of the girls:

It usually doesn't take much BudExplosion before the tips are browning. I am pretty amazed it hasn't affected them much yet.

Sadly those were sold before I started growing.
The blue one was a daily driver.
The green machine I sold soon after the refresh. No garage space for her.

First van at 17.
60 now. Doh

Good luck brother, can't wait to see what you put together!

When are you starting up again? I thought you were on a seed buying kick to pass the time?

Planning to build frames kinda like this article. Using 2ft eb gen 3 strips.

4 frames 10x24" each. 5 strips per frame. 2 drivers. Total of about 260 watts.

Gbox420 - LED Strips

LED strip lights In this chapter, we build an efficient grow light using LED strips and an aluminum frame, that also serves as a heat sink. Power consumption varies between 180W - 480W depending on the LED driver selection and the number of LED strips used.

I was a lucky mofo! Virtually everyone is sold out of the strips. Tried to buy another 20 pack. Nooooope. 6wks out!

Curious to know what drivers you are going to be using? Sometime ago I looked into DYI strips but really got confused on which driver to use.

Its an art and science designing, matching drivers to strips....series vs parallel...yada.
I plan to surround a cmh with the strip frames.

The spreadsheet a few posts up. Me figuring out how many strips per driver. 7 to 11 strips per driver in my case.
