Excellent description, and use of the form right up front. I appreciate that a lot, thanks.

In my opinion, you are #1 root bound, #2 using way to many ferts.

The folks at the botanical stores make money selling you those goodies and we all want the best for our little girls. BUT, it really can effect the taste of the product.

Look, I just use Cal/Mag as I RO to remove high iron. I PH adjust with baking soda. Fox Farms OF.
Veg only gets the OF and some NEEM foliar and light.
Flower gets some Molasses and Ultra snowstorm - and not a lot.

Nitrogen will make the product taste awful and you cannot cure it out. Plants should be repotted about every 3-6 weeks - depending - to fertilize and give the roots room to grow too.

Again, thanks for the great info, right up front.
