Autoflower nutrients

Once or twice a week. if it need more watering between then just water. This chart is a good reference point for auto feeding. They do not like strong feeds. https://www.autoflower.net/forums/threads/med-man-method-feeding-chart-ppm-ec.47856/ Best Of Luck!

With her being in wk 5. PPM should be between 7-900 at that stage when goes into heavier flowering they love extra cal mag. And around wk 7-8 I pushed my soil PPM to 1400 and no issues, cause I kept giving water inbetween even skip a feed or 2 if you aren't seeing any signs of deficiencies, soil is great for holding nutes, it's why there must be water feeds to break down what's remaining, and that alone after wks of feeding a nute build up your plant will live off water happily for a few feeds. Best of luck

Well for soil. It's 2ml of each nute per week in soil. You can either do this by putting 2ml/l. But starting off you'll find it hard for your plants to take that much water. Mix the grow+micro+cal mag together. Make up a l bottle 1ml of each, use 2ml of micro. Then increase by 1/3 after 2 weeks 1.5ml/l then into flowering 4wk switch to bloom+micro and you can increasw cal mag and micro by 3ml if mixing altogether. Then with that 1l give 200-300ml wait a day or 2 then 100-200ml water repeat nutes then water. Do not flush your soil. Giving waters in between will get rid of most salts and avoid nute lockout. You'll find it hard trying to fit in 1ml/l or 2ml/l of 3 nutes in 1 wk if giving them sep wit water in between, that part do not skip. Best of luck happy growing.
