Right now my media is coco coir with perlite. It is less expensive, and easier to dispose of, than rockwool.

Yeah check it out thenā¦ but the downfall is you gotta be medical to grow legally lolā¦ government ughā¦ but easy to get on the card kind of
Thanks for your input, I am a fan of AN pH perfect because of the chelates that make available all nutes to the plant independently the pH you have (donāt use pH pen). I bought this product because it already has them, that helps to dissolve them ā¦ 
Flawless Finish is also different in that it has a very broad range of free-flowing chelates. Nobody else has these. There are many individual metals that need to be pulled out of crops. Chelates come in different shapes and sizes and are attracted only to certain metals. The other flushing formulas donāt have a broad enough range of chelates to remove all the substances present in your crops.

Understood. In the presence of an acid, magnesium sulfate becomes chelated. Therefore, adding a few drops of pH down to the Epsom Salt solution can be an equivalent. The excess Magnesium and sulfur helps purge excess Calcium and Phosphate from the media. I use General Hydro 3-part nutrients and they also mix to a perfect pH for me.

Iām switching to Mega crops A and B after this outdoor grow. Iāve been using their Sweet Candy 0-27-27 and its top-notch Iām keeping my Bushdoctor Supplements tho
- Complete formula including all macro, secondary and micro-nutrients, using only ingredients and chelates immediately and fully available to the plant.
- Includes bonus soluble Silica, Amino Acids and chelates other brands do not have
- Should be used in combination with the Part B 15.5-0-0 Calcium Nitrate as a two-part system.

I see lots of posts about inconsistencies with mega crop; changing their formulations too often and not informing the community that they had re-formulated their mixture.
That, plus reports of nutrient fallout and cheap ingredients. I am not so sure about that product

Iāve only used their Sweet Candy I know they updated their NPK to 0-27-27 and are using old bags that say 0-0-16 but they did say this on Amazon. Their 25 lb. bags are updated on package 0-27-27 If their A and B is as good as this Sweet Candy. I will see on my next grow. Appreciate the heads up. 
I think @Esrgood4u uses mega crop

I used it for years and the results were always mega. A 22lb bag lasted me 4 or 5 grows including feeding my outdoors plants and vegetables.
Last bag I didnāt store correctly and ended up with a solid rock that Iām still chpping away at today 
My cannabis at the minute Iām using Ionic hydro. Itās cheap AF and its a one part veg and one part flower nutrient. Itās just easier for me at the minute with how hectic work is at the minute.

So how many ppms on the 500 scale would you say 10 percent isā¦ and how low to ph? For the epsom rinse?
Epsom salts cause an increase of ppm that is approximately 103 ppm when 1g is added to 1 gallon of water. 3g of epsom salts per gallon of water should make a solution of ~300ppm. That should be pH balanced to the best range for your media.

I see this a lot with people who use bottled pH up or pH down. Especially from canna-oriented companies.
You end up chasing your tail and buying more products when the root cause is the bottled stuff in the first place.
Once you stop growing with bottles and synthetics, all these problems stop.
To quick fix a pH problem, put a handful or two of gypsum in a quart jar, water, and a teaspoon or two of vinegar. Let sit for a day after shaking vigorously. Dilute with water and water into soil.
Water in lime to bring pH up, water in a teaspoon of vinegar to bring pH down. N and P also bring pH down, cations bring pH up.
TL:DR
The biggest culprits in growing are pH down/up, Cal/Mag, bottled nutes. These were all created in the industry back in the 80ās to force growers to keep buying more and more of their different products to fix a problem caused by their products

Yeah thatās what im learning. Iām currently looking into growing organically, I see a lot of no till but I donāt think I have the space for that so Iām gonna try just using Dr. Earth or Kis organic soil.
Feel free to ask any questions
Notill takes a lot of prep and i believe good soil needs some tilling once in a while.
Lemme know if you wanna start with bagged soil or make it from scratch.
Good bagged soil is G&B, Coast of Maine, fox farm (owned by monsanto but alright). Then you can mix with pumice, minerals, and foods
