okay soil, what kind ya using?

good soil, doesn't need to be fed for a min, esp if fresh....
usually just need compost teas, microbes, herbal teas etc....

I have plants at 37 days in 7 gal pots haven't fed a thing except the teas...
some would argue thats feeding...
I would argue yes, its feeding the soil....
in soil, at the age they are at, I dont see the need for cal mag, or notes, unless you're using a very bland mix...
which is great too just changes the way you feed blah blah...

good soil, should have everything the plant needs in veg... with just plan water really....
the worm castings in the soil and compost should provide enough base for soil life to grow with just the right environment and water....

how pot size, soil strength, how long you veg and then flowering are all different stories

if you feed too much nute in soil, and plant takes up almost none of it, salts can build, and calcium... can cause lock out... which looks like deficiency, tricky betch
