Hey Doc,
I use the same throughout no matter what I'm using because they are not an expensive exotic hard to grow decorative plant in a hothouse, they are just a weed.....
And the nute companies are in business to make a profit. There really is no need to have 6 or 8 or 10 bottles for just a weed.... but they will tell you there is.
I can grow just as good a crop using only blue grit throughout as I can mixing 8 bottles.
The only thing I change for veg / bloom is the spectrum. And I do that when they show sex as I like to stretch under a different spectrum than most.
My current grow is a goat shit grow. They were fed goat tea at 3 days old. They will still be fed goat tea when they hit 3 weeks old, and for Stone's gear which I plan on taking long they will still be getting goat tea at 3 months old.
Only the strength and volume will vary.
Now, tell that feed schedule to someone at a nute company and then sit back and listen to how the N P K is all wrong and how there will be this deficiency and that excess and these problems.... but you know what, I would bet none of them could even keep a seedling alive in it and yet I already know what to expect for my end harvest.
As
@The Elvis said.... reading plants is the key.
Once you master that you can use or do pretty much anything you want to do with these weeds.
Some can do it that way.... some see the need for 10 different bottles.... neither way is right, and neither way is wrong.... Do whatever works for you.
Peace
Hash
