So the concept in your mind over feeding and not letting anything run off, isn’t off. Many do this and fail.
Yes nutes stack over time, it’s whybwe have figured out over time, that 1: never follow the full strength on mfg, half strength, see what your plants do, every grow is different and there isn’t a “dialed in” true method. One has to figure this out. . True plants should uptake what you feed, but many factors prohibit this. Plant life stage, media, environment, lighting etc. it’s why go half and then as you learn what and how the reactions are you can “dial that in”.
2: feed , water, water, water, water, water, feed. That’s the tried and true method 1x feed for every 5 watering and or like I said, “once dialed in” you will know what works( for you).
3: flushing. There is controversy here but point to note, if you mess up, it’s works. But isn’t a cure all. In soil the build up is extremely hard to remove without some sort of amendment and or partial repot.
4: ph , though not a killer but very important nevertheless that every grower , Check the ph, AFTER the nutrient is mixed and before added, adjust the ph before you feed. Same for the watering cycle, though most tap water would work, provided the media has adequate amendments that will counter the additional load of higher ph water.
Lessons learned , tldr. Version
Learn your nutrient, the guy behind the counter isn’t your best solution, they sell products.
Use half to start, up as u learn
Feed vs water, 1-5ratio is the safest
Get run off every time, vacuum that up, and or Re-use , some soak it up and toss or re-water with it
Check ph, before feeding/ watering
Check runoff pH , and this tell you what your soil conditions are. Typically, 30 mins after first initial run of, do a second one and check that.
Amendments in soil are key to a good success, but all plans get shot to shit, so fear not! Lol lol. Live and learn bro.
Plant is nute burned and stressed.
Yank her, loosen soil. Get good nuetral soil. . If u are using nutrient, why get a soil that is so heavily amended? Salt farmers don’t need super soil, and super soil doesn’t need salt nutrient, just some light amendments as needed based on plant cycle and how she looks:
Hope this helps. I grow 50k in a commercial environment in soil and we do everything in super soil but are or have Trasitioned to
promix and yes it’s very “hot”. We don’t feed till The 4th week of veg. And we flush every time.
