Al's 5:1:1 mix when growing veggies in areas w/ alkaline water
I've read so many threads about Al's 5:1:1 mix that my head is starting to spin. Can somebody tell me if this sounds right for growing veggies (peppers, eggplant, cukes, zucchini, etc)? I get the pine bark fines, perlite, and peat and will mix those in the appropriate ratios, so here are my questions:
1. The water in my area is very alkaline, so I'm wondering if I should use gypsum instead of lime? I know that I would need to also add epsom salts to this.
2. If I go this route, how much gypsum and how much epsom salts to each 5 gallon bucket?
3. After mixing the soil, I only need to weakly fertilize with the Dynamix Foilage Pro (3-1-2) on a weekly schedule?
4. Pine bark fines, perlite, peat, gypsum, epsom salts, Foilage Pro. Is there anything else that I need?
Thanks so much!
