the big girls....Quasar, Emerald Jack, and Super Sour OG consume over 1/2 gal of water (+4tbs Big Bloom) every day.
After 48in or so, it starts to approach a gal.. My tips never burn or curl, in fact they usually point upwards at a 45degree angle. {2 or3 tsp Grow Big (veg.) or Tiger Bloom (flower) every other water} (B.Bloom is in there too)
Winter time it's a bit less, and indoors it's quite a bit less....but you're carrying a lot less foilage inside as well. Maybe it's the heat...but they droop fast if they start to dry out....I can tell by looking when I'm a couple hours late with the grub.
I love the way they perk straight up 2 minutes after the liquid and poop tea hits the roots
