Give her a little from the start and then increase it!

When the plant needs it. As often as it needs it.

Ohhh I wonder who is trying to sneak these past. 3 questions, all open, all waiting till they are out of site before selecting an answer. Let's see what names pop up on all 3.

Hey 👋, As mentioned below, it varies from soil to soil, so it really depends on how pre-fertilized your soil is. Each manufacturer has its own fertilization schedule, with its own quantity specifications - I would definitely stick to that, generally leaning towards 3/4 of the amounts.

all soils are different... let the soil work initially. react to symptoms as they come.. take notes as to the timing of it... form a plan for the next grow to pre-emptive cover these issues - maybe 1-2 weeks in advance start fertilizing etc... amp up according to what you learn this time. If you buy a different soil or it has issues with quality control/consistency, you'll have to go through that learning curve again, but it'll be easier. if you run across someone using that exact same soil product, they can give a better guesstimate. start slow.. amp up over time... i'd strongly suggest you let the plant show hints of symptoms before doing so if this is your first time. overfeeding is a zero benefit and leads to elevated risks. Gain familiarity before gassing it.

Depends on soil / "soil" and the specific nutrition. Coco, "Living" ... Tabs / Mineral / Bio / Liquid / Solid / Tea ...
