To get the most out of your nutrients you got to have a good calcium magnesium regimen
If you really want to see anything you are growing explode with growth and be vigorous have a good Cal Mag regimen and make sure you get some Omni a to go with that it is a from what I gathered is an organic nitrogen option that come you can buy but there is a difference when you use Omni a omniated is only ones I know of and it's raw mpk product and I've been using mpk Raw all their products for years and they are hands down the best on the market if you use them correctly I found that using them every 10 to 14 days is more than enough and you will see your plants leap if you use it right if you use it weekly and don't measure it correctly then your plans to do okay but you will not see them just leave with growth less is more people and it works I was not paid to say this I'm not being given anything I'm not with one of those programs where you get to keep something if you give a review this is me spending thousands of dollars to grow Bud flower sticky and it is the good stuff and this makes part of that happen and you want to stress your plants just not with nutrients what I found is to buy grow and Bloom separately use them with nitrogen potassium phosphorus humic algae Cal Mag of course and on the a vitamin B amino acids and I don't use that you can yuck or whatever I just don't and you going to see it and you'll see it big but the boosters for like three flower midflower late and in flour or incredible it's just a mix of your products without blooming grow but you stop your amino acids at Bloom and so save you some money there oh and the beneficial bacteria or is a must look for sales cuz this stuff can't get pricey and I spoke with them about their close your problems and I'm still having them it's a ziplock so if you work with it it's great but some of them fail a lot of them fail to be honest so make sure you have some closure material closure clamps for extra bags on hand because if you're in a humid area it will ruin this product some of it

Good stuff
Basically I use this as my plants need certain needs separately. My soil uses Gaia green bloom n veg, so I had a potassium issue and bought this and phosphorus, nitrogen, potassium with cal mag. It's useful when your balanced soil is great just missing certain nutes by its self. Saw major difference with 1/8 in gallon in 3 days.

Steroids for plants
This line of fertilizers, individual nutrients or the grow and bloom lines you cannot go wrong. Which ever you choose CalMag is a must, itโs great for tomato plants for blossom end rot. Also great for coco coir growning plants.

Good Cal-Mag
The recommended mix is for 1/8 or 1/16 teaspoon per gallon of water. I wanted to start with the lower dose of 1/16 teaspoon per gallon. So I boiled 16oz of RO water and added one teaspoon of Cal-Mag powder. I stirred the solution until the powder completely dissolved and then poured the concentrate Cal-Mag into a storage bottle. Now I just mix 1oz of my Cal-Mag concentration with a gallon of water to have the 1/16 teaspoon per gallon of water dosage. This is going to save me a lot of money on Cal-Mag!

IT REALLY IS GOOD FOR YOUR PLANT.
Excellent product provided you use according to directions. <Now, after using it a few times, zi FUD add alittle more than suggested, but was careful. Also, I only used it once every 3/4 weeks>. If your plant needs a boost, try it. I used it in a pointsetta in an 8 inch pot. The plant was 13 months old when I started. I've used it 3 times.
