I just started using Plagron PK 13/14 and mixing with my nutes caused my nutrient solution to go cloudy af. Is this normal? I’m thinking about using it once a week as a stand alone because it just didn’t look right after mixing it.

it's probably mostly monopotassium phosphate, which is a common ingredient in all sorts of products, not just p/k "boosters." At normal-use concentrations, shouldn't cause a precipitate but the order you mix fertilizer can make a difference. Make sure all fertilizers are thoroughly mixed before you add anything with a lot of calcium. Calcium is mixed in last. silica, if used, might be best 'last' but that's only going to be a low ppm concentration by comparison. you probably dont want to just give 13/14 -- well you can, but it's not a complete diet on its own. It's assumed you already considered how much p and k you provide with normal fertilization. don't just randomly dump more of anything into the pot without knowing what you already provide. "more" is not always better.

Never mix nutrients or meant to mix together please read info below When nutrients fall out of a solution due to incorrect mixing, the process is called precipitation, and the resulting solid is a precipitate. For plants, this can lead to a condition called nutrient lockout, where the nutrients become unavailable for absorption. Precipitation Precipitation is a common chemical reaction that occurs when dissolved ions in a solution form an insoluble solid. This happens with concentrated nutrients for several reasons: Mixing concentrated parts: Many multi-part nutrient formulas must be mixed one part at a time into a large volume of water. Combining concentrated parts (like a calcium formula and a phosphate formula) directly causes them to react and form an insoluble compound, such as calcium phosphate. Incorrect order: Certain components, like calcium, can easily react with others, such as phosphates and sulfates, if not added in the correct order. pH imbalance: The solubility of many nutrient salts is highly dependent on the pH of the solution. If the pH is too high or too low, some minerals can form solids and fall out of the solution. ……

Plagron PK 13/14 is highly concentrated in phosphorus (P) and potassium (K). When mixed with calcium-rich feeds (like CalMag, certain base nutrients, or tap water with high Ca content), it can cause cloudiness or flocculation (tiny particles binding together). This means part of the nutrient mix has fallen out of solution — it’s not fully dissolved anymore. How to Fix / Prevent It 1. Mix Order Matters: Add base nutrients first (A/B or main feed). Adjust pH if needed. Add PK 13/14 last, slowly, with good stirring. Never mix PK 13/14 directly with concentrated nutrients — always dilute in water. 2. Use Clean, Warm Water (18–22 °C) to help solubility. 3. Check EC — if the mix spikes way too high, dilute it. Cloudiness can be a sign of overconcentration too. 4. Don’t Mix With Enhancers or Organic Boosters in the same jug — especially ones like enzymes, humics, or bio-based calmag, which can destabilize the solution. Using PK 13/14 Stand-Alone Yes, you can use it as a stand-alone supplement once a week during mid- to late-flower. Typical use: Add it to plain water (no other nutrients). Keep pH 5.8–6.3 (soil/coco dependent). Apply once per week or every 3rd watering. That way, you avoid interactions and get a clean phosphorus/potassium boost. Keep growing ganja farmers! And be nice, bigup 💚😊✌️

Cloudy normally means a participate has formed and reacted with something locking out he nutrients and creating undesired reactants.

From what I believe when this happens is because of high pH already in the solution.. Lower the solution to below ph6 before adding the pk and see if the problem persists.. Hope this helps.. Good luck..
