Advanced nutrients and autopot

1.3-1.5 EC 1-1-2 ratio of npk and 421 if KCaMg will get you in a good ballpark. every fertilizer formulates concetration differently.. that is irrelevant. it matters how it is concentrated when mixed together. Regardless of brands, these molecules function the same way. pH around 6 will do you good. Any reputable soilless/hydro nute-line should be ph-balanced and buffered to avoid drift, otherwise the manufacturer is incompetent. do a weighted average of %s off label to find the ratios.. doesn't have to be exact.. not meant to be followed exactly... think my weighted average NPK is 8-9-15 for example... i use PPM so i'm not as familiar with the ratios. These ratios are definied by years of study. They are not some rambling of a home grower but from proper sample sizes and proper experiements... multiple professional Ag companies have products that follow these rtaios.. even some marijuana brand companies do too, liek athena and floraflex, but their products cost 5x more for some reason.. irrational reasons... Be religious with 10% runoff waste water. -- down drain or outside but not for use with potted plants. This avoid buildup caused by watering habits. any issues you see regarding nutes will be about dosage and never buildup. this is helpful when diagnosing issues. Once you do a little fine-tuning, you'll rarely see a symptom. i run several strains from same reservoir with zero issues and rarely see any leaf symptoms. Sometimes i have to dilute a pot or two (automated irrigation, then top off with some plain water to dilute). Those are athe plants that are a bit more sensitive to nutrient levels. Easy enough to mitigate. but they still want the same ratio of nutes because that is based on what constitutes the plant.. leaves, stems, buds are still all made in similar way, even if slightly different strain to strain.

I never tried coco, but usually the dosage given by ADN official recipe is accurate. But as @m0use would tell you, ADN tends to be a bit overpriced and have a f5g lots of cans (using the full line, preparing the sauce take time, it start to piss me off myself). Maybe try another line (you seemed interested in Plagron last month, that's not a bad choice). However, on the question of Auto pot and coco, I'm sorry I couldn't help you: I've never been tempted by growing in coco and in soil I prefer top flooding. And indoors now I prefer DWC. :3
