Daily/Weekly ppm for a plant ?

It all depends on the size of your plant, small plant's can't tolerate a lot , very big one's will eat everything you throw at them, if yo have been feeding that much all this long and it looks healthy then you are good .

it doesn't add up like that. I'm assuming this is soilless/hydro context based on how it was described. if religiously getting 10% runoff or appropriately swapping out the water often enough in a reservoir, buildup in substrate should not occur. The plant will tell you if it is too much... and it may take several weeks or even months to see a deficiency or toxicity form. The more slowly it occurs, the better the formula is or the smaller the adjustment required to fix it etc. There are too many moving factors to give a one-size-fits-all overall ppm or individual nutrient ppm breakdown. The nutrients can antagonize or stimulate other nutes -- meaning you may need more or less based on the ratios/concentration of other nutes that are dissolved. Elemental ppm is what matters. There are free apps that can calculate what this is from gauranteed analysis labels and tabulate it for you across products. Keeping track of this isn't useful until you learn what has great results in your plant - i.e. observable results. At that point you can become familiar with a safe range for each nutrient molecule that consistently resutls in fast growing and healthy plants. If a formula works for some plants and poorly for others, don't fall into the popular belief of blaming the plant for being picky. it's more about a flawed formula that only few plants can mitigate. This tidbit is from a primary source and can be verified. The trick to fertilization is not providing nutrients at the same rate they are used. Due to involvement of active transport, which relies on feedback loops to control intake of certain nutrient molecules. The key is maintaining 'enough' nutrients around the roots and in proper ratios so that each is readily available and easily taken into the plant. Turns out this is not the same as the ratios of use inside the plant. Mass flow is anything that can 'fit' in will enter the plant with water. Some molecules may be too large to traverse the membrane, but in those cases you rely on microbes and such to break it down into a plant-available molecule -- this is only relevant for some "soil" fertilizers. Active transport sends out a carrier protein that will only bond to specific types of molecules and then drag it back inside the plant -- all about concentration gradients and probability. Humans also have active transport going on in our small intestines. This is why studies show that once you provide 'enough' P/K, more doesn't do shit for yield or potency (contradicts marketing and popular beliefs) but does runoff down the drain unused because the plant relies more on active transport for these particular nutrient molecules than say N intake. Something like 60% of P/K enters via active transport. As long as it is readily available around the roots, it's enough and boosting over that never helps the plant and more likely locks out other things. What UV said about converting EC shows how useless those TDS meters are. The EC measurement itself is accurate and precise, but it does not convert to ppm very accurately. Calculating elemental ppm from gauranteed analysis labels gives a clearer picture of what you are providing to the plant. Beware of any extravegant, overly-sophisticted fertilization regiments. Add this here, or add this for 2 weeks there... this stuff is never tested.. never compared to a control group, never proven to have any real effect and certainly never had an appropriate sample size in the first place to come to any rational conclusion. Hypotheses are not all created the same. An untested hypothesis is useless conjecture. These overly-complicated methods are pure masturbation. Like mouse said, you always need to observe and adjust. Local variables will make it less likely you can use the exact same formula as someone else. Just having a slightly different ratio could cause a different 'optimal' dosing need for some other component (see/google "Mulder's Chart"). A well-balanced formula will require very small adjustments, but you may still find tox or deficiencies very slowly creeping in and that is your signal that you needed to provide a slightly different ratio leading up to that point. The rate at which a deficiency or toxicity occurs is very telling about how well you are feeding.. slower it occurs, the closer you are to providing the correct amount over time. A good formula can work well for 95-99% of plants. The belief that these plants are picky is a product of poorly balance provision of nutrients. People too often blame the plant first before their own behaviour. At that point, you can't improve anything and doomed to mediocrity. Wildly swinging nutrient content around the roots is not a positive.

WELL 5K A WEEK IS CLOSER TO 714PPM A DAY. DAT IS TO HIGH FOR WEEK 9 OF FLOWER FOR A SATIVA. THIS CAN LEAD TO NUTRIENT BURN OR TOXICITY. I SUGGEST LOWERING DOWN TO 1000-1200PPM A WEEK. DAT SHOULD DO YOU VERY VERY GOOD!

While 1 ppm in soil is generally 1 mg/kg, and in water, 1 ppm is roughly 1 mg/L, One gram in 1000 ml is 1000 ppm. Harder you push growth the more ppm you will need over the same cycle time. Ppm can be read using a tds metre. The units for TDS are usually expressed as milligrams per liter (mg/L), which is the same as parts per million (ppm). Ec can be read using a ec metre. Ec should read somewhere 0.3 -1.8 never higher than 2.0 To find out ppm in a soil, while there's not a single, universally accepted conversion factor from EC to PPM, common conversions include multiplying EC by 500 or 700 to get a PPM equivalent. To convert 1.5 EC to PPM, you can use the formula EC x 700 = PPM. So, 1.5 EC multiplied by 700 equals 1050 PPM. Alternatively, using the formula EC x 500 = PPM (500), 1.5 EC would be 750 PPM (500). Water water water till EC tells you to. Best luck budddddieeeee.
