where are you growing? english isn't your first language is it? very nice grow thread, i will be keeping an eye on it all season hopefully! have you tested your ph? it's very easy, take a small scoop of dirt and mix with water, then dip a litimus paper(ph tester for fish tanks, very cheep) in the water and bam, i dunno you may not need it but i would keep an eye on it if i were you. plants are looking great bud, keep up the good work!
