5-11-26 that mimics Jack's
6-30-30, 5-10-40, 5-50-1.
Then there are the formulas with urea
My main question at this point is k level.
I'venever looked into Growmore but I use General Hydroponics Maxi series, dry. It's just about $4/lb from Walmart.com for both the 15-5-14 (maxigro) and 5-15-14 (maxibloom) it's got all your bases covered for micros. Free shipping!
55 gallon rez, from eBay I supplement about
- 1/4 cup Calcium Hydroxide cheap, like $1/lb and dissolves really well
- 1 cup Magensium Sulfate also cheap, like $1/lb or so
Going into week 4+ flower I supplement Monopotassium Phosphate from eBay also forget how much but also cheap.
