Friends need your advice! What PPM should I keep in the flowering stage in coconut coir, now my cake is getting 900 ppm but that seems like a lot to me ?because of the color of her stigmas and long development, What is the best level to stick to? I'm already confused

Hi. You can see how the plant is feeding on the PPM of the drainage solution. If you pour 900, and from the bottom came out 700, then it is possible to increase the nutrition a little. And you have to keep in mind that the PPM of mineral and organic fertilizers are different things. On purely mineral 1000 in some cases will be very much, and on organomineral or organic fertilizers 1000 PPM will be little. Your plants are looking good. Leave it as it is for now. Use a periodic cleaner to clean the roots and substrate of insoluble calcium carbonates that are blocking nutrition. And you'll need to switch to a blooming circuit very soon

The nutrients you are using will come with recommended dosages and the company that makes them/sells them will offer a feed chart which should state the EC/PPM requirements at all life stages. Just google "advanced nutrients feed chart coco". I use EC rather than PPM but my understanding is that 1 EC = 700 PPM... autos need less than photos, but my photos are currently taking about 1500 PPM in hydro and they are roughly at the same stage of (a longer) flowering period. So 900 PPM is probably about right (but I do not use AN myself, so it's best to check their recommendations).
