Id say similiar thing to Mike, Burn and deficiency go hand in hand... The nute companies have pushed this myth on us that we gotta dump insane amounts of their "secret sauce" on these girls... Yes cannabis is a heavy feeder compared to lettuce but think about other heavy feading plants and how we fertilize them... Tomato is another hungry plant and there isn't a veggie gardener in the world that would feed their tomatos the way we feed cannabis...
Flush like mike said, but flushing in and of itself is terrible for a plant to be all over the board with nute levels... A necessary evil kind of.... But strategically slow and steady wins the race... I've gotten down to 1/4 dose of cheap ass Jacks and I've not surrendered a bit of quantity or quality. You know what I don't have anymore though? Burn and deficiencies... Even if we don't burn em, the over nuting is what causes a lot of "deficiencies" because of imbalance and lock out... And I've been there myself, I used to dump it on em and dare myself how strong I could go with nutes without burning them and I loved saving up to buy a pint of something that cost $130 cuz it had to be good at that price. Then I decided to try the ultra basic nute route and dared myself to give one round a try with as low of dose as I dared of Jacks (If you aren't familiar with it its a horticultural professional grade nute with no sizzle or naked ladies on bottle- but its complete with micronutes and such for fraction of the cost)- I've been on the low dose, no-hype nute bandwagon ever since.
Like salt in soup-easy to add more, pain in ass to get too much out. If you feed light, if your plants get hungry looking its easy to add more nutes and they will take them up great and be in great shape in no time. slow and steady, low dose, and quit buying into nute company marketing of more is better, both in concentration of the nute in water and quantity of bottles on your shelf.
I'm not a soil guy but a coco dude, so exacts I cannot give you- but the concept of: we as a whole over nute these poor plants to no end is true regardless of grow medium and in doing so we complicate ours and our plants lives...
