And that's how you do that. lol that's 4 2gals? that's a shitload of weed for 8 gallons of ...coco? You covered how often but what are you feeding them beasts?
I run Jacks Hydro + Calicum Nitrate @ 1.0ec in veg and 1.2ec in flower. Week 5 i give them 2 doses of MKP (0-52-34). The only other thing I add is sm90 @ 4ml/gal which handles any fungus gnat issues that might arise
For the price, ya really cant beat it.....for me anyways
