I do have a question... How long did that take you? I have just started my 1st hydro setup and am also using the Lucas Formula. Im just curious to see how long that took to get that big. Im having yellowing on the tips of my leaves and am still trying to figure things out. any input?
well, I think I am going on about my fifth week from seed. I started to have yellow tips but they went away when I moved from the 5/10 to the 8/16. I guess I was under feeding them a bit. Are you still on the 5/10 mix? Also what is your PH sitting at?
