budswell is good but expensive. you can make your own nutrient tea out of guano, alfalfa meal, Maxicrop and molasses. The same price all together and you can get about 20X as much with great results
I use hydrozyme on my plants and they love it. Keep using it
The purple shit is just a product that gives your plant phosphorous toxicity before you harvest for purple buds
i personally wouldn't use it but i wont tell you not to.
Hope this helps
