What are EC and PPM? How do I make sure my nutrient solution is the right strength?
EC stands for electrical conductivity and PPM stands for parts per million. And they’re both measurements to make sure your nutrient solution is at the right concentration.
(This depends on the nutrient that you’re using, but a typically comfortable range is 0.43 to 2.6 mS/cm (millisiemens per centimeter) or 220-1280 ppm.)
We suggest using an EC meter to measure your nutrient solution and sticking to the recommended nutrient rates on our products.
For seedlings — don’t exceed 300 ppm total.
For vegetative plants — 900 ppm total is your safest bet.
For plants leaving the vegetative cycle and entering flower (12/12 hr light) — it’s best not to go over 1350 ppm.
Keep in mind, these are general guidelines. Some plants might love a little ‘hotter’ solution while some might not, but at least now you know the starting sweet spots.
I have pest problems %$&*! What can I do?
Dang… sorry to hear that. It happens to the best of us.
But no matter your skill level, the answer is the same: Eradicate the bastards.
The most common indoor pests are spider mites and fungus gnats. If you aren’t able to confidently ID the bug, take a contained sample to your local grow shop or take a picture and send it us or look online.
In many cases you can use organic remedies. Depending on what you’re growing, there are different types of products out there. Do your research to be sure you’re fighting the right insect. Also, make sure an insecticide can be used on your specific plant and make sure to follow the correct harvest intervals before ingesting anything you grow.
How do I fix plant browning if I have a meter?
High performance growers might have a meter (EC or PPM or TDS) to test the runoff.
(No worries if you don’t. While these meters are great tools, you don’t need necessarily need one to grow.)
Here’s an example of how to fix plant burning if you do:
Say your leach solution registers at 200 ppm and your reservoir after leaching the first time is 600 ppm. You’d continue to leach until the reservoir runoff is less than double the starting solution or in this example 390 ppm or less.
Each time you leach try running your system for 24 hours of pH-balanced water before dumping and remixing again with fertilizer.
Once your solution is 390 ppm or less you’ve just successfully hit ‘reset’ on your plant and it’s ready to start feeding again.
How do I fix plant burning without a meter?
For plants grown in soilless mediums — leach out the excess nutrients and salts by watering with pure water (adjust pH to 6.0) until water drains out the bottom. This may need to be done a few times depending how severe the issue.
Try a 1:1 ratio for any system that drains to waste. So, with a five-gallon pot, push five gallons of pH-balanced water through the root zone to make sure excess salts are removed.
For plants is soilless systems — the principal is the same, leach the root zone by passing pure water over the roots until most excess salts have been removed. This great way to correct over fertilization, deficiencies or toxicities.
Try running your system for 24 hours of pH-balanced water before dumping and remixing again with fertilizer.
Why are the tips of my plants brown and dry?
There’s a good chance what you’re seeing is plant burning caused by an excess of fertilizer. No worries, you can stop the damage quickly by changing out your reservoir water and using a lower dosage of nutrients.
(But keep in mind that if the leaves have burned you’ll have to wait for new leaves to grow in their place. Burning is usually permanent.)
Why do some people use water filters for their systems?
Everyone’s got there own reasons but will list the most common two:
1. Hard-water — Hard water has an excess of minerals, usually calcium and magnesium, that can cause buildup and damage to hydroponic systems over time.
2. Chloride excess — Although calcium is an essential plant nutrient, it can become toxic at much lower levels than other nutrients. Some growers remove contaminates in order to have complete control over everything that touches their crops. Municipal water suppliers can analyze your water quality or you can determine whether you have hard water by testing the PPM* right out of the tap — anything above 240 ppm has high levels of calcium and iron and is considered hard.

Why is my water pump always clogging?
If your system is clogging it’s a time to clean it out.
Soak hose lines in hot water or a simple bleach solution — one tablespoon per gallon water — to remove buildup. NEVER LET BLEACH SOLUTION ENTER THE ROOT ZONE and always thoroughly clear out bleached lines before feeding. Check hoses to make sure no debris is left after washing. If your pump has a filter, remove it, rinse it, and if there’s a lot of wear and tear, replace it.
Is it okay to mix different nutrients for my plants?
Absolutely. Hydro growers often create their own unique concoctions. (But it’s always good to know the basic rules before breaking them.)
The Basic Rules:
Base nutrients – these contain everything plants need from seed/clone to harvest. It’s not a good idea to mix multiple base nutrients together in the reservoir because that can cause over-fertilization making your nutrient solution toxic to your plant.
For instance, if you’re using a two-part base nutrient like Black Magic Base Nutrients A & B and then add another base nutrient, you will alter the balanced nutrient profile that A and B are formulated to give and risk feeding your plant an unintended toxic concoction.
Supplements — Plant-enhancing micronutrients (or supplements) like Black magic Bloom Boost or Black Magic All-Purpose Supplement are compatible with Base Parts A and B. Don’t go too crazy though, sometimes less is more.
Start with the base nutrient for a few grow cycles and then try additives to enhance your plant’s flavor, aroma, size, color or bouquet.
Oh, and don’t mix fertilizers together before diluting them completely and never pour back into bottles to avoid contamination. Also, it’s always best not to mix nutrients in a reservoir where roots are growing if you don’t want to burn the roots… trust us, you don’t.
How do I take a cutting and successfully grow it?
Cuttings are a great way to start new plants (Though we’re also huge fans of growing from seed).
To get started just dip the cut end into a rooting hormone solution before planting in order to trigger roots. Then carefully plant into the soilless growing medium of your choice or into a Black Magic Seed starting plug.
