Hoestly mate you don't need to over think this stuff. Just quarter to half strength the nutes. Feed as often as you can be bothered. As long as it going in at that range and the right ph the rest will just fall inline.
I know there's a thirst for knowledge and it's hard to just trust someone (especially a random like me that you don't really know) that it will work but honestly man that's all there is to coco.
Just keep feeding the stuff with weak nutes and they go like the clappers.
You don't need to worry about the pther intricacies cos they won't pop up.
Other than N tox or PK burn which are too strong nutes, pretty much everything else that goes wrong in coco is usually a side effect of not feeding often enough.
I've got all the stuff there to just turn my coco plants into a Wilma type system so I won't have to deal with any of it ever again.
Just fill a 20L tub with quarter strength nutes. Stick an £8 pump on a light timer to go on for 15 minutes 4 times a day. Done. 2 plants will sit in 3gal fabric pots on the lid of the tub with holes cut in it so the run off drops back into the tub.
I'll empty the tub once a week and top it up if it gets low.
Once the bottoms go yellow I'll go from quarter up to half strength and that's all the thought process I'll ever have to put into it. The nutes will be running through it too often to be effected much so I'll get a week easy before it starts going out of range.
Once they're big enough to start really drinking it I'll have to top it up every couple days but I won't need to change anything. Just more volume nothing else. It will balance itself out.
Just can't find my little plastic adapters to make a feeding ring. I know there here though so just have to wait till I find them.
Measuring the run off is handy for when things are going wrong as it can narrow things down and help with diagnosis but if nothing's going wrong you can just ignore it.
We explain things in a fair bit of detail when we can so it can make things sound overly important. It often is fairly essential that you understand these things but that doesn't mean your plants are gonna die if you go a bit off track.
Things don't have to be perfect the full grow. Especially in veg. You got all the time you want to get the hang of this mate. While they're in veg you can fix anything that goes wrong and just veg them longer if it's needed. By the time you go into bloom you'll understand everything you need to.
Just chill out and let them do their thing mate
