Oh we all have gotten hit by the sales pitch and the desire to grow better buds, or more of them.
We can mess up the floral stage, but the only time they should be used is during that first week of bud onset, when all is just going to start, so the plant has that extra nutrient kick to get started flowering.
Over time I have learned, or I think, the floral process is a series of stages, weeks by some, and so at each stage the nutrient diet that the plant desires changes a bit, and with hydro or coco, inert medium, one can see very nice end results, but I have learned to not add much near the end as if all grew correctly there is still a lot of stored nutrients that can be used with in the plant.
Soil is truly a different game and there is a lot to learn with it, if one is seeking to be at that level. I do not get a lot of vegy's to grow here for me, not as I would like, so I do believe I need to learn more about what shit I have, what it needs, and how best to supply that to the soil beds so that I can grow something I can eat. Get that down and you will grow great weed in the same soil, and when flower time comes around a mulching of additives may be used or needed, here a soil test should be done to see how the NPK is at that time to determine what is needed, if anything.
I think it boils down to the grow and what they are after and want, some do not care, others do care to a point, and than others care a lot about that end product they are going to smoke or use, and than we have those that go over board, to some, as they love the plant and feel they can be one with the plant ( a super good understanding of it all) is how I see it.
I do not think I answered the question,
I am good it is Shatter Day, just smoked more to make up for the difference.
