I like to start the first week of flower St about 5-6 yea, Those agent ks are hefty feeders too!
Like I said a few up though, if nitrogen is a worry then either drop the feed level for the last few feeds or give it plain water for a few drinks before harvest
Thanks again. Itās funny cause my clones of the Agent are loving the maxi at 7 grams a gallon but, the ones in flower are showing signs of an N deficiency at only week 3 and I sometimes need a p/k boost with it anyway depending on strain. Donāt mean to be a pita but, how many grams a gallon of Epsom are you using when you feel you need to add a little?
@GreenleafNutrients. Quick question if you donāt mind but would it be ok if i used liquid kool bloom as a pk boost with the newest version of MC? Itās all I have on hand at the moment.
yup, you can use any PK brand. iirc LKB is 0-10-10.
Just keep increasing MEGA CROP dosage until you reach the maximum āGreenā level you are comfortable with your plants. Then afterwards you can add a 0 Nitrogen PK boost from there (any brand is ok).
Thanks. Just gave the girls in flower a 1.7 ec feed so, hopefully they improve.
Are you in coco coir?
No, I grow in āsoilā . Pretty inert and loose to work well in my bottom feeding Octopots. 1/4 roots Organic Original, 1/4 Sunshine #4, 1/4 worm castings, 1/4 perliteā¦many runs on the same"soil" . Just clean it, dry it, re use it every run , after 4-5 runs I add more worm castings, that is about it.
Thanks. Thinking about just mixing my own raw salts and trying to understand all the numbers and everything like your post above but, just canāt seem to wrap my head around it. 
Just ordered the free sample off of your site! Can I really use just this start to finish?
yup!
Iām still kind of newā¦ but I was under the impression that I need a higher nitrogen # in veg compared to the other nutrients?
Our CalMag product has pretty high Nitrogen content if you feel you need to boost for whatever crop you are using.
Thanks for the info. I ordered on sunday and it got here today so Iāll be trying it soon!
Iāve been using it as one part outdoors and adding in-the pk boost. Works great for my projects. Plants respond very well in both veg and flower.
Is the calculator on the website still putting out v2 numbers on the calcium and magneisum or is it putting updated v3 numbers?
Calculator is up to date.
@GreenleafNutrients How much % calcium is in the v3 mix? This is all correct and up to date? I pulled that straight off the website.
It would be nice to see the version attached to these charts because thereās a few charts out there.
Had to put the MC V2 aside to use as a secondary source of fertilizer due to inconsistent results that I donāt have using my own modified Lucas throughout ten + years. I will be using the last though for the transition from veg to flower with the plants that need the higher nitrogen and can benefit from this and the rest will be scattered throughout the outdoor gardens if it doesnāt turn into one big clumped ball with the slightest exposure to humidity.
yes it is correct 
Did you pull that from the product page? There are two different numbers for copper on that label (.02% and .04%, right below it)ā¦
Also, this image is from the same (product) page:
The numbers are different between the two pictures on the same page. Whyād you choose the label image you chose?
