The stems on my plants (12/12/CFL's @ 9 weeks total) are streaked with a purple-ish color. Sort of green/purple/green/purple...Is it a prob or ? The stalks are like fire hydrants. Very strong for their height. Using Shultz's Bloom Plus in the water. Does the streaking indicate strain or sex? Gotta know soon. Pplease? Sid, Ray, anyone?
as long as your not overdoing the fert it is most likely the strain....mine is like that at the moment, i can post you a pic if you'd like....same strain but only one has it!...weird eh?......Peace out....Sid
