Ito flower feed sched canna?

OH -- equally important -- get 10-15% runoff... waste water, do not let it re-absorb. Toss it outside or down drain. wait for top layer to change color... it should get a little dry, but not quite like 1" deep in "soil"... allowing top layer to dry will help prevent pests and microbial growth on top. 1/4"? 1/2"? when i used coco i just waited for color to change (lighter brown). Learn weight of pot at this point as it is a better indicator to familiarize yourself with. Simple lift of pot tells you all you need to know as to when to irrigate.

coco is soilles, it should be fertilized every single irrigation. 650-750ppm ... with an autoflower 650 is probably a better starting off point. check any of my diaries for a table of nutes ppm... start off near same ballpark and you'll be fine. One caveat, i have hard water, so you may need more Ca/Mg/S than i use. N 120s ppm P 50s k 190-210 These depend on hardness of water used to mix: Ca - 100ish Mg - 85ish S - 110ish being off by a handful is inconsequential.
